Spec me a PSU please

Hello,

Currently building a new system over the next couple of months.

Found out I won an Asus RTX 3080 ROG Strix OC yesterday, so my current PSU I was planning on re-using isn't up to the task, so I'll order that now, then I have it already when the 3080 comes. Will need one with 3 8-pin connectors.

Specs wise it'll likely be an B550/X570 with whatever 5000 series CPU is comparable to a 3900X, with a 360mm AIO, with at least 9 120mm fans, possibly 12 all together.

Don't really have a budget, would prefer to keep it below £200 though.

Cheers.

Total: £123.65 (includes shipping: £8.70)

Thanks, Corsair was one of the brands I was leaning towards, whats the difference between this and the i and x models they do as well? Other than the price obviously.

The rmx uses better quality capacitors and fan

RMx is what @mickyflinn said
HX is further up the 80+ efficiency chain
i on the end of any model is the Corsair digital link models that allow you control & monitor that PSU.

I wouldn't bother going any higher than RMx TBH. 80+ gold is more than enough efficiency for most users unless you run your rig 24/7 at full load. Corsair digital link is just something else to hog system resources or to go wrong.

Thanks for the help everyone, just need to wait for stock to appear now, seems to be no PSU's pretty much anywhere.

Stump up the extra and buy this.

12 year warranty as well.

Bit of a bargain.

Cheers, I did go with this one in the end. Was another one of the brands I was looking at. Just installed it this afternoon, ready for when the 3080 turns up.

Just had the RMx 850w delivered today. A bit overkill for my upcoming Zen3 build as it's either being paired with a 3070 or possibly an RDNA2 card (if they show up with a particularly price/performance offer) but was only a few pounds more than the 750 so might run in silent mode.
