Post by: Kiriakos GR on July 07, 2022, 09:40:55 PM
Another special moment for ITTSB Blog and readers.

SEASONIC Europe along headquarters of Sea Sonic Electronics Co., Ltd Computer Power supply ODM (Taiwan), they become sponsor of product samples for the upcoming ITTSB Blog products review and presentation.

We agreed that readers will find this content available approximately not sooner of last days of September and later.
Elevated summer time temperatures in Greece this is No1 Issue, the No2 issue this is that I need to prepare my testing lab with new test tools addition.

I did gave a promise for original and unique, high quality content production, and this is what I will do.

Nils at Seasonic EU, he did approve this new marketing project, the arrived carton box has inside much more than just samples.
We are now at frequent communication, and we even develop a personal friendship, he is also an expert warrior in life and we do have much in common.

SEASONIC delivered to me:
The well known  PRIME TX750 Titanium  SSR-750TR   ...............   (Unit Production date May 2021)
Their very fresh  PRIME TX700 Titanium Fan-less  SSR-700TL  .........   (Unit Production date March 2021)
Their also fresh G12 GC 650 Gold  A651GCAFH  (equivalent  of Seasonic industrial  series build quality ....  Unit Production date January 2021)
   
7 July this is also my name day, and coincidence or not, Seasonic incoming samples along gifts these gave me lots of positive vibes.  8)
I have outdoor 36C and 31C indoor, I can not touch this Seasonic shirt for now. 
But at September and later on, it will be usable.   ;)

What I do enjoy at Kiriakos skills as photographer, this is that he does not simply taking pictures.

He is always finding the way to demonstrate a portion of personal inspiration by the use of OLYMPUS camera lens along the gentle use of Greek humor!   8)

Congratulations mate  :)

I am not in a hurry, but is there any updates?
Any new schedule of product review release date.

Its a fact that Kiriakos did extreme amount of work so far,  and he did it alone with out external help and or financing.
He did build a triple DC load with his bare hands.
He did activate his AC power source, which delivers locked voltage output at 220V (2KVA wattage) that is an expensive and rare tool, this now assisting at power analysis evaluation.
One God knows how much unseen work did so far.   :)  (Greek saying)

All true  ;) 

Quality testing its not simple as by your self to use expensive measuring tools.
There is power efficiency formula, which I had to discover and familiarize about using it.

There is a Japanese electrical standard, this dictates of how pulsing PSU evaluation this it should be made.
I had to translate the Japanese standard in to English, and even use the help a Japanese friend an software developer.
It was Japanese text within images, that no automated translator this could help.
I had to build a special probe for my oscilloscope, this suggested due the Japanese standard. 
 
I had to prepare Excel spreadsheet, an master form so to print and write to it, entire number of required electrical measurements.
So to transfer testing data in to the new dedicated spreadsheet = per PSU model evaluation, which this will be shown at my product review article.
No to mention that I have three PSU to test.

Neither God and neither my self, I was aware of how many preparations I should perform and of how extremely time consuming they are.
Seasonic told me to not stress my self too much, marketing team its well aware of how much hard work required, if you do not own any automated testing system, for PSU evaluation.

This week I will collect all required electrical measurements.
Then I will need two more weeks for webdesign.
As an athlete would say:  I am very close to the finish line, but not there yet.  ;D

I could not imagine that PSU testing this requiring such a huge amount of testing tools.
And so much time for personal preparation, handbooks reading, special tools making.
A pile of electrical measurements and also confirmation.
I would never do such a job free of charge.   :) 

Kiriakos selected the long hard way, not like most others did,  they simply install the PSU in their computer and run few games and benchmarks for testing so to make a review.

“Power supplies based on ATX 3.0 and ATX12VO 2.0 will ensure anyone looking to get the most stable and cost optimized performance possible with highest power efficiency out of their desktop PCs will be able to do so – both now and in the future.”

–Stephen Eastman, Intel platform power specialist
----------------------------------------------------------------------------
Beyond system performance, the ATX12VO spec is going to be integral to helping the PC industry meet multiple governmental energy regulations.
Recently announced regulations for complete systems – such as the California Energy Commission’s Tier 2 appliance efficiency requirements – make it so that OEMs and system integrators (SI) must use extreme low system idle power levels to reduce desktop idle power consumption.
The ATX12VO specification is one of Intel’s efforts to improve efficiency across OEM/SI systems and products for our industry partners.

ATX Version 3.0 Multi-Rail Power Supply Design Guide in February 2022.
This was a significant update to industry power supply specifications and led to considerable change in the IT market.
-----------------------------------------------------------------------------

Just reading a standard with 89 pages, its fun but I am limited in speed.  :)

According to latest standard, they are specific directions of how Stand-by power this it should be measured, and special mini DC load required for the 5VSB rail ( I need to make one).
The long story in short, my review and electrical measurements will be performed according to latest INTEL standard, and any one who did testing according the older standard, any comparison points these are now invalid.

I might need another one month, but my product review this will be worth reading for the years to come (2023 production).  ;)

ITTSB Blog Introduction

Expectations from modern made computer PSU as offered advantages:
Reliable power delivery
Low noise electrical DC output
Electronic protection circuits
Improved power efficiency
Long life

Non-essential parameter for evaluation this is 5VSB rail (PSU half activated), and it’s all about low and high in consumption of USB devices and specifically about mobile phone charging.

About Seasonic TX-750, the company mentions TX Series as their upper class of offered PSU.
Indeed, Seasonic this using electronic components these selected from most well-known sources.
   
Now I will start the myth busting process, one computer PSU this is two power supply units within one box.
5VSB this is an independent power supply unit, this is the only one obeying at power efficiency specifications for low-wattage and or lowest power consumption.

When a PSU this fully activates, it entire power efficiency this changes, at power-On action, powerful semiconductors these taking over, and they are now responsible for the delivery of the energy (at all rails), and these are also responsible for the total of PSU power efficiency score (Silver, Gold, Titanium).

 
Power supply manufacturing industry / semiconductors development industry
There is no power supply design possible without available electronic components to use.
It’s one product designer he has several options of semiconductors to use, low cost, high cost, fresh design, old design, and he is responsible about the selection of entire number of electronic components too.
 
Seasonic this is not any charity institution.
It’s a company which it did build it reputation by the delivery of highly reliable products when the customer (consumer or an industry) accepts to pay the relative asked cost.

PSU evaluation at ITTSB Blog, electrical test and measurement advance lab. 


I am Kiriakos Triantafillou from Greece, born at 1969, certified as industrial electrician since 7-1988.
Title of Industrial maintenance electrician this is two specialty pack in one, 60% electronics plus 40% electrical work.
Outside of factory walls I am freelancer at electronics repair and since the year 2007 I did also began getting involved with Switch mode power supply repairs.
 
At the year 2010, I did began thinking of me to become founder of electrical test and measurement equipment reviews Blog, this targeting to inform other working professionals (people with developed skills) about best choices out there of related products.

At May 2012 I did succeed to activate ITTSB Blog project, and eleven years later, history did recorded my activities and international occasional marketing level collaborations with significant names of our times, as is Agilent-Keysight, FLUKE Corporation, HIOKI  E.E  Corporation Japan, GW Instek Taiwan, BRYMEN & DER EE Taiwan, Megger UK,  Times Electronic UK, Vishay Foil resistors and of many more.

Today my plan this is of me to talk to the world about SEASONIC (Taiwan) work, solely about the TX PSU series. 
Due the fact that TX700 fanless this uses identical technology with the TX750, I did focus at testing TX750 alone, in a way that it has not been reviewed before.
 

PSU Testing methodology at 2023
I did focus at the verification of Seasonic’s latest development or claim about +/_ 0,5 % 12V Rail MTLR (DC voltage stability when input AC voltage this fluctuates), along 12V rail voltage stability with load testing.

With an AC stabilized Power source at 220V, I did testing by monitoring all three voltage rails at two conditions of loading, at 10% and 50%.
My resistive load this uses resistors as load for 3,3V and 5,0V rails, along halogen car lamps these to stress the 12V rail.
The activation of halogen car lamps, this creates over-current spikes these be enough as torture test regarding the inspection of DC voltage stability.
Detailed information’s you may find at the chart below.
 
My second test this was about the verification of +/_ 0,5 % 12V Rail MTLR (DC voltage stability when input AC voltage this fluctuates).
The guideline of how to perform this test this found in Taiwan, due a brand this manufacturing DC loads of very high power. 

The tests process this requiring a high power Variable AC power source, along of a Variable DC load.
The DUT (device under test) this should be evaluated at entire AC input range according to product electrical label.
For the Prime TX750 the test performed at voltage input range of 90V up to 240V.
TX750 this tested at 55.5% of load due the potentials of both combined DC loads that I own, electronic programmable along the resistive one.

Two interesting pack of measurements came out of that testing.
I did my first evaluation, just with 80W of test load, and then repeated the test at 477W at 230V.
The interesting factor this is PSU power consumption increase as mains input voltage this decreases below the 120V mark.
 
Below are both pack of measurements, at 80W and 477W of max load.
 


Test results Evaluation and conclusion
In the beginning of my engagement with Seasonic marketing team about this product’s review, I thought to perform anything at my powers so to deliver an extremely complete electrical product evaluation.

And so, I did even invite several well-known brands of test equipment, so them to collaborate for a common presentation and of their latest products these relative to PSU evaluation and measurements.
For unknown reasons, I did realize that they were not interested (Japan, Asia, and USA).
 
Additionally I did realize that Seasonic marketing, this is not acting that well, when test results outcome this is sugar-free.

A third realization of my, this is that Seasonic has a favorite Group of PC product testers, them not qualifying to perform any PSU evaluation, even so I did were attacked from their master brain from Cyprus (he did feel as inferior and nervous when it came the time so him to compete against a real electrical measurements expert).
 
Gentlemen I am certified professional, and any one not respecting me as such, he does not worth any of my love either.

In conclusion I do deliver the measurements as they were recorded, and anyone alone he is welcome to do the math.

236V ---- 477W    ---   80W   (PSU consumption due mains)
200V   --- 476W     --- not tested
120V   --- 486W    --- 81.0W
110V   --- 534W    --- 89.7W
100V   --- 612W    --- 103.8W
90 V   --- 745.1 W   --- 124.5W


12V Rail evaluation 90~236V   80W load
Min: 12.27694
Max: 12.27963
Average: 12.27963
Standard deviation: (SD) 370.000uV

 
12V Rail evaluation 90~236V   477W load
Min: 12.32056
Max: 12.32261
Average: 12.32157
Standard deviation: (SD) 457.424uV


Sum of tests these were performed under Greek heatwave, indoor temperature 34.2C, even so TX750 this never run warmer than 40.2C

Wow.... so the Americans at the event of Mains under 100V mark, the PSU wastes 250W on top of actual Load, even with a highest in efficiency PSU.  :(
In other words they are forced buying oversized models, just them to be at the safe side.

The regular Gaming PC at 400W max of consumption, this has nothing to be afraid when using PRIME TX750 Titanium ( SSR-750TR) in the U.S.A.
I have mention this advice countless of times at computer PC forums, you must measure upfront Gaming PC power consumption prior making a NEW choice of PSU wattage.

The rich boys, they should pay for up to 1200W of total power PSU, otherwise they will burn their electrical panel fuses.  :P

Last question for now, why the voltage measurements according to JEITA standard they appear a bit higher?

Last question for now, why the voltage measurements according to JEITA standard they appear a bit higher?   

JEITA this is Japanese standard, which I translated in English, and I even needed some help from a Japanese friend of my.
The Japanese industry agreed to make written PSU testing guidelines, so all electrician engineers to follow.
One of these tests, this is voltage measurement by excluding voltage drop caused by the cables.

I do not have control of who will read this product review, it might be youth?  It might be people with technical background but inexperienced?  And or could be engineers who have certifications along professional test equipment? 

Either way I have a message for the ambitious them thinking to act as PSU products reviewers (testers).

The planet of electrical test and measurement, that is the source of test equipment of all sorts, this is defined and knows to experts as I am, and this is a market place too.

The sector for AC power measurement and or about power analysis’s, this is the most hostile speaking of equipment retail prices.
Any brand producing such equipment, they expect professional test lab as customers and they will provide equipment along training, along annual calibration services for their equipment.
The idea is the factory and producer of such test equipment to gain a permanent customer.

Another path to follow for power analysis, this is the use of very expensive Oscilloscope and of several High-End probes for voltage and current, and due the measurement of COS F (Phase shift / difference), we are coming close to own an partially accurate test system.

Both paths at 2023 will demand a financial cost of 30.000 Euro as minimum.

In the world of Oscilloscopes, all 8 bit scopes they are not noise-free enough, for power measurements at low AC current.
Basic accuracy of Oscilloscopes and of probes, this is another challenge, if you are aiming to compete with measurements presented at 80 PLUS certificates.

The Japanese industries were forced first to manufacture such special Low-noise current clamp probes, and single probe pricing this is today at several thousands of Euros.
 
The European industries still produce the medium in performance special Low-noise current clamp probes, and the best comes at pricing point this be close to 500 EUR, special design for power analysis.
 
-----------------------------------------------

 At my attempt to use my oscilloscope as professional power analysis tool, I did discover the entire pack of challenges at current waveform review and Phase shift measurement when special AC/DC clamp probes are used.

Quality probes compatible for power analysis with BNC connector they do not grow over trees.
These are upper-class advanced engineering and when the source this is European technology, then this is even better.

I wish to thanks PICO Technology UK, for the sponsored sample of TA189 AC/DC oscilloscope current probe !!
TA189 under the hood, this is work of (UK based) subsidiary company of GM Germany (R&D and production year 2010).
In summary: TA189 this is developed due power analysis specialist.
It has also won a place at automotive diagnosis as current leakage probe due it superior noise rejection for power electronics applications.

PICO Technology UK this is 12 bit USB oscilloscopes developer.
And today I do feel extremely proud, for the privilege to be the first reviewer worldwide of this superior European probe.
I might enjoy it at full potential if its Gods will to get in my hands a true upper class of 12 bit Oscilloscope in the future.

https://www.ittsb.eu/forum/index.php?topic=1778.0


---------------------------------------------

Final thoughts, the pricing sum of SeaSonic incoming test samples = 600EUR retail, the pricing of single probe for current measurements = 500 EUR.
It is essential for us professionals, to perform investment calculations even for the thought us to purchase electrical test and measurement instruments.

My verdict, if you do not have a customer paying you for the production of electrical test reports, then you do not organize such a sophisticated test lab.
There is no medium price point so to organize a sophisticated test lab.

But for us experts of electrical measurements, we are able to come closer to measuring perfection, by combining ingenuity and expertise, along manual math calculations, but the test results has value only for us alone.
When a fully automated measuring system this comes at high price, the next path this is using a few of your own brain cells if you do have any.

Dear Kiriakos,
Only few people following you from a close range as I do, we have awareness of how many adventures you did faced alone, so far.

You did pass thru smaller amount of happy moments and a larger of disappointments, because others did not respond as you may expect.
You did use at that project, best test equipment that very few others own.
You did make, ACV source and DC loads with your bare hands.
You did make special tools, these to aid power analysis due oscilloscope, and the oscilloscope this double crossed you.
You did study piles of technical documentation, so the test patterns to be by the book.

My advice, you have prove your own high potentials all these years, now unplug the damn thing from the testing harness and plug it at your own PC.  :)
Your earned technical experiences this is your GOLD to keep.
Stop to worry of other people thoughts, we Greeks we do have a code of honor that very few foreigners can understand and or appreciates.

Thanks people !!

Well I have not say yet my last word on this topic.  :)
I am now collecting data from my PC with an old 780W PSU of 2008, so to gain proofs and to measure actual benefits of  modern PSU efficiency.

My APC SUA1000XL this includes VA power meter along data logging.
And I did collect few screenshots for future reference / comparison.

And I have also collected comparison data these taken by a low-cost  wall-plug power meter.

For today I will add screenshots from the APC software and data logger.   ;)

No1 problem detected at all PRIME ..
No chance to get a good photograph of their Chrome Labels  ;D

New PSU installation when smoothly!!
I did remove a good working PSU, and install another fresher good working PSU with a Titanium 80 Plus label.

First test was by the use of APC SUA1000 (VA) UPS.

Today that PRIME TX-750 this is plugged at my PC, I can finally compare this PSU regarding power efficiency with another two quality PSU of my glorious past.

HIPER POWER HPU-4M780-PE--  Efficiency  85.0% Max --- 80Plus Bronze --- Year 2008
CORSAIR CX-750 --------------- Efficiency  88.5% Max --- 80Plus Bronze  --- Year 2013
Seasonic Prime TX-750  ------  Efficiency  94.6% Max --- 80Plus Titanium – Year 2016

All PSU brands and their marketing people, they try to brag about power efficiency as a key selling point.
I am a consumer of PC computer hardware since 1996, along a certified electrician since 1988.

The race started when the concept of 3D Gaming PC this born at the year 2002 and later.
From the year 2002 and up to date, we measure 21 years of computer PC PSU evolution, which is a chain of constant received improvements over the basic electronic design.

First and a true benefit of a PSU with better electrical Efficiency, this is much less heat generation within the power supply.
Heat this has two paths to follow so to be shared at the environment (our room).
One portion of heat this is removed due air flow.
Another portion of due PSU caused heat, this is transferred at the metallic computer case (PC tower).
The computer case which has become a heat trap, this will lower the effectiveness of air cooling at all components.

The second benefit of better electrical Efficiency, this has to do with energy savings within a yearly period of PC computer use.
Most western families nowadays they own three computers PC per household.
So if all three computers using a better PSU, then the yearly savings at the power bill them are significant.

My own workstation this is:
INTEL i7 4770, Z87X motherboard, DDR3-2400, GTX 1660 6GB graphics card, PCI legacy add-on sound card, four HDD, one SSD along of one DVD recorder.
All components air cooled, CPU cooling with highest in performance air cooled tower, PC case a real full tower of 2003 (HEC Taiwan).

Electrical power consumption measurements were taken by the use of wall plug power meter, the usual of 12 Euro (dollars) item.
If this measure 10W and above of power, the measurement includes lesser error.
       

Bellow I will deliver data of three computer PC operational conditions.
a)   IDLE
b)   Watching  a 1080P movie
c)   Gaming  with a very demanding  3D game

HIPER   --------- CORSAIR ----- PRIME
a)   Idle
103 Watt = CORSAIR 7W less ---- 15W less …  ( 88,5 Watt  (473mA) PF 0.77)

b)   Watching  a 1080P movie
127 Watt = CORSAIR 8W less ---- PRIME 33W less … (94 Watt 0f consumption) 

c)   Gaming  with a very demanding  3D game
HIPER = 220~305 Watt variable consumption
PRIME = 220~230 Watt variable consumption (PRIME = 243W Max Peak)
PRIME = 75W less energy waste than HIPER

In conclusion any power bill benefits they are elevating according to how much power your system needs at gaming mode.
And now with this rough comparison, we can now estimate the benefits (energy savings) at a Gaming PC (internet sports configuration), at 450W of consumption the gain will be 100W less energy per hour if you were using instead an 80Plus Bronze of the year 2008.

Now consider 75W or 100W of removed energy waste due the PSU efficiency, as thermal load, this now is removed also from your PSU internal electronics.
And or imagine the impact of having an active 75~100W Incandescent bulb within your PSU, which is the equivalent of an active heater. :P

What worth to remember for future use? ;)
Best PSU efficiency score of our days = 75~100W of lesser heat generation, this aloud the manufacturing of FAN-LESS PSU these able to have equal long life cycle with the active cooled ones.
FAN-LESS PSU this is mainly a product to serve at sound recording studio.
My personal preference this is actively cooled PSU,  especially when I do own, PC case of specific design (classic small server Full tower).

All right,  let's declare it a HAPPY END   ;)

But its interesting, the APC SUA1000XL VA power meter, it cannot sense or measure power factor at all.
Plain VA meter this is good enough to determine safe load for the UPS it self, rather acting as power meter.

Who cares... life moves on,  this APC its technology of 2003, its a miracle that this is still alive.
Happy for you mate !!  8)

Comparisons and more comparisons,   :)

I wanted to find out if I can use my motherboard as bench-top DMM  :P 
Extreme resolution at 3.3V rail,  lesser at 12V and much lesser at 5V.

I did confirm the measurement and directly from the ATX 24 pin (Gigabyte GA-Z87X-UD5H).
12V & 5V Rails.

U1272A DMM = 12.210 V
GA-Z87X-UD5H = 12.168 V  = 52mV lesser than real  =  0.344573% difference 
At the 5V rails, the motherboard is 42mv lower too.
I will need to send the motherboard back for calibration.  :D

I did and another comparison, all rails output VS the older PSU.
They are very similar, but the PRIME it does boost the 12V rail.

Even so it is an very interesting comparison and or a electricians class lesson (education).
A newer PSU with 10% better efficiency, at plain VA measurement this measure only 1.9% lower than the older PSU.

HIPER ...  Game load = 34.4%
Seasonic .. Game load =  32.5%

Kiriakos, what is the average of your PC daily consumption according to low cost power meter? (KWh)

Kiriakos, what is the average of your PC daily consumption according to low cost power meter? (KWh)

On average my PC this is powered 11 Hours per day.
About 9 Hours of internet usage or editing documents, or editing photographs along email use.
Along of 2 Hours gaming .. my way out.

Within five complete days,  with the Prime TX750,  the power meter this measured 6.7 KWh.
I need approximately 1.35 ~ 1.5 KWh per day just for my computer alone.
 
I do prefer turning it off when I am not at the shop.
Suspend to Ram = Sleep mode this is now 4.2W,  with the older PSU it was at 6W.
The fresh booted workstation PC this is better working due my experience, especially when this is loading significant amount of third party software at its boot.

About a year ago, I did trash several software packages that they was acting as system monitor.
And I did focus at learning to configure HWinfo-64 so this become my tool.

At HWinfo forum,  I did find Thomas Barth (Tom) which is software developer of Generic Log Viewer that is a software which help you to analyze and review, any file recorded due HWinfo.
I did help the man with some fresh ideas, so him to improve the graphic interface,  so the measuring results to appear as more meaningful.
We worked for three months,  Generic Log Viewer this now a complete project, it include markers and other editing tools, and you can make a precise review of any recorded parameter.
Tom loved our collaboration, he is software engineer, I am expert at measurement, and his work now gained a greater value as analysis tool.

Any PSU its just a black box prior this gets paired with a motherboard.
Them the energy this start flowing at 24Pin ATX, GPU Six pin, PCI-E plug, CPU , and all over the motherboard.
As soon this happen, then we have an enormous amount of measuring points.

When any PSU this is paired with a motherboard, everything change speaking of voltage rails stability.
The better motherboard this makes the difference now.    

Gigabyte GA-Z87X-UD5H this is a Monster of quality,  at the electrical sector along features.
At gaming mode, the PSU gets stressed, but the motherboard this has also several power related subsystems which these compensate and increase overall voltage stability.
At the INTEL Z87 boards, the CPU this is mostly in control of all voltages, its acts as general manager, in control of all MOSFET array along other power components.

At gaming mode, the Seasonic TX750 along with the motherboard, it deliver rock-stable 5V and 3.3V supply,  and only the 12V rail this suffering from slight unbalance,  due the dynamic load this named as GPU (3D graphics card).

While the NVIDIA, MSI GTX 1060 6G this is a king of the past, this is not insignificant as DC power load.
NVIDIA recommends 400W or greater power supply.   

I did take several screenshot for your education.
Rails 12V 3.3v 5V
12V at PCI-E socket
12V at PCI Express 6-pin connector ( This could look as evaluation of Seasonic cables / harness)
The last one its a proof about the MOSFET over my motherboard ( year 2013) that they do deliver 95% efficiency at DC to DC conversion. 

Since the period of RTX3080 I did discover the unseen, that NVIDIA did several huge mistakes, the chip causes huge dynamic loading (current spikes),  the PCB even as huge in dimensions, its full of components which them are sum of heat sources, that the air-cooling solutions this is unable to dissipate this huge amount of  heat (energy watts).

In the past three years the rich home users, become victims of their passion.
They thought that product engineers are stupid,  and they wasted huge amount of cash, for getting magical thermal-pads along magical thermal paste.
Additionally the PSU industry it was unable to predict of how much problematic will be the RTX3080 speaking of power rail dynamic loading.
The gamer's which faced first the problem, ended buying OVERSIZED In Watts PSU, and they did waste FURTHER more cash.

THE SUM = tremendously expensive graphics card  + significantly expensive PSU + magical cooling toys
And me which I was member in several  computer relates forums, I ended as banned because I was THE NEGATIVE voice in this madness.  :P

The calendar reads 10/8/2023.
My computer system cannot stress enough the Prime TX750, highest consumption under 3D benchmark this is 266.4W
Under these tests even the Prime TX650 this it would be sufficient too.
According my statistics, NVIDIA RTX this is a huge in design failure, if you are up to get one, RTX 3060 and or a similar in performance from the RTX 4000 series, this it would be the lesser evil for you to be paired with.   :)
