Hi,
After some research and deliberation, I recently bought a RTX 4080 to replace my 2060.
I also need to upgrade my PSU and I'd like to go minimum of 850W or future-proof to 1000W.
I was advised that I also require gen 5.0 PCIE. I've googled this but am a bit lost in the results. If anyone can help then I'd appreciate it.

ATX 3.0 Power Supplies at Overclockers UK

Upgrade to incredible performance with an ATX 3.0 PSU, designed to offer the power delivery and reliability modern PC gaming hardware requires.

you want a atx3.0 psu...designed for the new gpu and can handle the power spikes the new more powerful gpu's can create. they'l either come with the 12 pin connection in the psu or like the corsair shift, come with a cable that converts into the 12 pin which you plug into the gpu..
i'd go gold, and look at the warranty also.. good one will come with a 10yrs warranty...then it'd down to price

below is on offer..the msi has a native 12 pin connection, the corsair comes with a cable(connections slightly different to standard anyway as slightly smaller)..i have the rm1000x shift, but the msi is a decent psu also..cheaper, so i'd prob plumb for that at mo if buying ocuk and wanting 1000w



my basket at ocuk:

Total: £143.99 (includes delivery: £3.99)​

PCIE5 refers to the 12 pin (12+4, 4 sense pins) connector that is present on all nvidia cards from the 4070 Ti and up.

PSUs either have a native connector that is a 12 pin from the PSU-end to the card-end, or they use an adapter.

Most (probably all, idk) 4070 Ti, 4080 and 4090 AIB cards include an adapter where you connect 2, 3 or 4 PCIE 8-pins and get a 12+4. In some cases, this is the only PSU config that the AIB will cover under warranty, i.e. the use of native or custom cables are not covered.
 
Thanks for all the help. I’ve just finished swapping out all the cables from the PSU. Just one thing that I’m not 100% on. I have a supply labelled 12VHPWR on the PSU but it has a different number of ports than the 12VHPWR cable I bought. My previous GPU plugged in to the PCIE ports. Is this ok to do the same?
This is the cable I bought:

That cable is pointless as your psu nativly supports 12v HP and that is a pcie 8 pin*2 to 12v HP adapter.

Just send it back and use the native one in the psu box.

The cable I got with the 4080 was a
3 x 4 pin in to a 8 pin
The one I bought was a 2 x 4 pin in to a 8 pin
The PSU cable is 1 x 8 in to 1 x 8

you don't *need * pcie 5.0 it would just be *preferred*, 4.0 has less max bandwith than pcie 5.0, it means the gpu wiill run ever so slightly slower than if you had a pcie5.0 slot in the best circumstance(ie gpu running at a high percentile)
but don't worry about it until you next upgrade your motherboard

it'll be fine
