Given that Intel announced the standards and I'm looking to build a new PC, I'd like to future proof it as much as possible.
Are there any PSUs compliant with the specification already? How much would buying now would hamper me from changing GPU in 3-5 years?

Thanks!

You do know that its an announcement? It'll take ages to come out and your GPU will be fine for the next 3 years.

It's not making old tech no longer functional, it's improving tech going forward.

You'd still be able to buy an ATX 2.0 GPU and PSU in 10 years time.

Fair enough, it's just that I've seen warning about it in review so I wanted to be careful...

What review? Were they saying "ooooOOhhh ATX 2.0 standard bad. 3.0 is everything"

Scare tactics?

Just enjoy your system, they aren't out to make your GPU no longer functional.

Quoting: "The PSU doesn't have a 12+4 pin PCIe connector, meaning that it isn't compatible with either the newest ATX spec (v3.0) or upcoming GPUs. It is not ideal to buy a PSU right now because we are in a transition phase from the previous ATX spec to the new one."

This is what got me worried about...

Toms is just writing that for clicks.

They don't honestly care, it's just a point to make to fill the review out.

There's also no mention of that in the Against section of the review so I wouldn't stress.

Which PSU are you looking at?

The main feature(s) in the ATX 3.0 standard are;

1. The current 'proprietary' 12pin connector for the 3xxx founders edition GPU will be added to the other PSU connectors (ATX 24pin, ATX 4+4 pin, PCI-e 6pin & 8pin, SATA & legacy connectors such as Molex & floppy disk) pretty sure the last two will be phased out as they are hardly used on PC's anymore.

2. PSU Design will be adapted/improved to cope with the insane power draw & power spikes of modern GPU's to eliminate or reduce system instability.

In short, if you don't plan on getting a high end Nvidia GPU for your new rig you'll do just fine. There'd be an outcry if current spec PSU's were withdrawn & new Spec PSU's were incompatible. Never gonna happen.

Finally, I'll wager that Seasonic will be First to market with an ATX 3.0 spec PSU.

Just lol! :)

Just because a new standard is comming, and not even available yet, every one panics and thinks they all need a new PSU? hahahah!

Your (presumably good quality) ATX 2.x PSU is not going to suddenly catch fire and burn your house down at 12.00 midnight when ATX 3 comes out. FML.

See also DDR5, even though its worse than DDR4 at the moment, and massivley more expensive.

My worry is not about now but rather in about 5-6 years, when it will be time to get a new GPU. Will I have compatibility issues by then? Will I need a new PSU?

It's more of an issue for the motherboard in my opinion, because that will be very different to what have we now, with only 12v, but there are already proof of concept adapters available for this (albeit, you'd lose the efficiency benefits at idle). GPUs should be no problem, since we already have adapters and they can make more.

As far as I know, there's no consensus that these changes are going to go ahead. Even if Intel push it with Raptor Lake, it is rumoured to only apply to the low-end.

Assuming the PSU is has enough power, then at worst you'll need an adapter cable(s).

The PSU isn't doing anything different, it's just doing it's AC/DC conversion thing like it always did.

I wouldn't worry about 5 to 6 years time. Buy whatever PSU you want now and if you happens that you do need a new PSU you will have had 5 years use out of it!
