How importent are PSU ATX versions?

[Shou Miko]

Lately after my recent hardware change to AMD's Zen5 I been wondering of it's also time to upgrade my current PSU which is ATX 2.x something to the newest ATX 3.0 even I don't use the 12VHPWR plug and not planning to go Nvidia.

Current my system is listed so not gonna put it in, this here is just me thinking because I don't think AMD will go with the 12VHPWR for their 7000 series gpus.

Don't worry about it, you are fine without HPWR connector for quite some time, and you still can buy 8-pin to HPWR adapter if needed.

I seen the adapters and the reviews and Nvidia almost calling customers stupid when they have issues with them, I feel the connector is a laughing stock.

I was also thinking about the ATX standard since I see more and more people with Gigabyte motherboards having issues and myself with my Z590 Vision G as the only motherboard which up right turned off on my 1.2KW psu.

The only sensible reason for making this change would be accomplishing something impossible on ATX 2.x. Which I have severe doubts about given the plummeting base components quality of electronics in the aftermath of pandemic.

I'd wait until they offer something you actually need for a price you need it at.

ATX 3.0 PSUs can handle a 100% (of the 12V capacity) Transient Spike. and depending on what kind of crazy GPUs we get in the future, it is well worth investing in one if you plan to buy high end hardware.
i have a RM1000X (2021 Edition) and can trip OCP with a 6950XT tweaked with MPT. a 750W ATX 3.0 PSU wouldn't have any issue with that.

Use a quality unit with the proper connections you need. If you don't need a 12VHPWR, you are fine.

Interresting, I haven't had a GPU tripping OCP.

I use SeaSonic. I got their Prime 1.2KW for my main PSU now and I have a SeaSonic Focus PX-750 as a backup from last year if needed. (It was cheap so I brought it).

No, you just need to buy GPUs that don't suffer from massive spiking, such as Ada or RDNA3.

Ampere and RDNA2 are a change from the norm, and not something likely to be repeated. They both suffer from glorious inefficiency and/or poor node.
Whereas you can run a 318W 7900XT on a 650W PSU.

In general though of course, high end components do want quality PSUs, but shooting for 1KW simply isn't likely to be necessary for a single board/GPU gaming rig, unless you're going to be looking at north of 400W TDP GPUs. And that's pretty extreme territory, also in cooling (case).

the 6800XT is really on the edge with a 750W PSU. both of my 6900XTs could trip my 850W NZXT C850 (which can run my 4090 in Furmark at 500W with no issues!)
and once you overclock, hitting high frequencies at high power with MPT (380W instead of the stock 284W) even a single rail 1200W PSU gives up sometimes.

Der8auer trippe his AX1600i Titanium with a 7900XTX pulling 580W.

For anything above entry level it's worth getting an ATX 3.0 PSU.

From your system specs:

Seasonic Prime 1200 watt 80Plus Platinum
(Backup Seasonic Focus PX 750W Platinum) | 65W

Not sure what that "| 65W" is - it would appear to be a laptop supply. So assuming you are using one of those Seasonics, and assuming your computer is running fine now, there is no reason to buy a new PSU.

So to answer your question of "How important...?", it is only important if your hardware requires it. And your current hardware does not.

"IF" I was in the market for a new supply today, I would look to get the latest version for future proofing. But I will not, and do not recommend buying a new supply just because a current supply is not the latest ATX standard.

Yes the 65W is my Lenowo USB-C charger.

The Seasonic Prime 1200W is in my main rig and the 750W is backup because it was cheap.

750W is backup because it was cheap.

Cheap as in you got it for a good price. But not cheap in quality as that is a quality PSU too.

So I say, relax. You have a very nice system, as is. Enjoy it.
