ATX 3.0 PSU for 4090 and future cpus

Soulja · 29 Nov 2023 at 20:03

Hi all,

I'll be building a new PC next year, and I'll be wanting to pair my 4090 with one of the next gen cpus that will release next year. Do you guys think a 1000w will be enough or should I go for something with a bit more power?

If you're buying a CPU with the equivalent power draw of a 14900K (or plan to overclock one), then yeah, 1200 isn't a bad idea for the headroom. It is less important if you're only gaming.

The X3D CPUs have very modest power usage, but how the next gen will be, I have no idea.

Soulja · 29 Nov 2023 at 22:03

Yep, it will be for gaming only. I'll keep an eye out and see if any good 1200w PSUs pop up in the sales. Thank you!

Which 1200W PSU would people recommend? I'm looking to spend around £250.

hwbusters have a review of the Vertex GX and PF3, but it appears the Vertex is quieter and it now has a longer warranty, since Seasonic extended it to 12.

Their review of the new RMx 1200 (Shift) also looked decent, but side mounted cables can be a compatibility issue.

I have the Vertex GX 1200W, runs my 13900k and RTX 4090 with no problems. Very quiet during load.

I have a Vertex GX 1200 as well, it’s very good. Also has a 12 year warranty. The only annoying thing is that there has subsequently been an updated to the 12 pin cable but I don’t think any manufacturer has got round to implementing it yet (I might be wrong).

I think that's part of the ATX 3.1 spec, according to this article....

ATX v3.1 & PCIe CEM 5.1 are official! - Hardware Busters

IIRC there is an MSI (?) one that offers a new plug for the 12 pin cable. Not that it is 3.1 compliant

Oh for gods sake haha. Honestly this is the most ridiculous situation I’ve ever seen with power supply specifications EVER in the history of PC’s.

Oops, obviously I mean 3.1 spec........................but who knows

Yup, if you read that article it gives an impression that 3.1 seems a little at odds with the 3.0 spec, in terms of transient spikes.
Kinda glad that I do not need a PSU as yet.

Could be worse, Intel might try and push the BTX std again, lol.

My seasonic vertex 1200w gold died and tripped all the sockets in my house last week, getting it replaced with the platinum model and hoping it's more stable.

Your PC not plugged into a surge protection block then?

No, don't stops sockets going out, just flicked a switch and they all came back on.

Ah do they not? Got both my rigs on their own SP blocks, didn't know it wouldn't stop that happening. Is it just purely to stop too much going through the block/back into the device plugged in then?

There's a few PSUs that are shipping with them without it being specified.

Of course, it’s already a mess why would they want to clarify anything for the consumer…!

I'm looking for a new atx 3.0 psu. The new MSI look nice

MrMacca · 1 Jan 2024 at 19:15

I'm currently in a similar situation after having the same superflower psu for what feels like 10 years and thinking it's about time I upgrade.

It is a good Power Supply, a long Warranty, Jap. capacitors, great voltage regulation
