    Hi all, I was wondering if you could just sanity check my PSU selection for the following configuration. I have a BeQuiet 1000W PSU Dark Power 12, the PC build is for a watercooled system, not yet built:

    CPU: Intel 11900K OCed at 5.1/5.2ghz
    GPU: NVidia 3080 EVGA XC3 ultra, mild OC
    Drives: 3 x m.2, 4 x ssd
    2 x D5 pumps
    14-16 120mm fans

    Depending on which online configurator I use, I get a range of recommendations from 750-1200W. I was wondering if there are any views here on this? I had understood 750 would be recommended, so went 1000w for some leeway.

    Much appreciated :)

    1000w seems a sensible choice allowing for power spikes, anything less i wouldnt feel comfortable.

    Thanks @mickyflinn . Same question for same spec, but with a 3080ti instead. Looks like power consumption for 3080ti is 350W, compared to 320W for the 3080. So it's +30W with the 3080ti

    Better to have too much than just enough, you never know what the next few gens of GPU`s power draw will be.
