I expect to hit 500/450 wall/output power after overclocking the CPU.

I'm running into some money in a year or so.

Think this would run four Volta video cards in quad SLI fully water cooled and delidded 7980XE at 5+GHZ?

Likely be the very last high-end PC I'll be able to build unless I hit the lotto or something. redface.gif

im most likely running around the same build as you but with an overclock but i dont think i should be pulling 660watts at all, i only thought maybe i did because my PC just shut off but could be unstable OC or mem, never had issues with them before tho.

My point exactly. I can imagine 600 W if your EVGA has 360 W power limit versus my 300, and considering your seriously high CPU voltage. But no more than that.

Agreed, sadly anything under 1.43volts and i cant boot with 3.9ghz

Yep, you'll be perfectly fine on that thumb.gif.

Yeah that unit would handle that load. That unit is 230V only though so if you're in north America then you'll need to run a special circuit for it.

Also, 4 way SLI is a waste of money outside of a few benchmarks and specialized rendering workloads. It's not officially supported so expect it to get worse over time unless DX12 EMA gets better.

You could buy half as many GPUs and a CPU that's half as much money and most likely get the same performance, then a few years later you can buy a new machine with the money you saved. Unless you have a need for something that high end I would recommend that course of action.

i think i would rather build 2 computers for the price of 4 way SLI lol. that way i could have an AMD and an intel system biggrin.gif

I own a Strix 1080 ti and i am hitting power limit which reduces my oc clocks.
I flashed the xoc bios, but i noticed that i was hitting 1.125v without touching the voltage slider. Is this safe voltage for 24/7?, i have ordered a ek waterblock so cooling wont be an issue in few days.
If that is too high, how can i lower it to safe voltage?

See the first post in this thread to learn how to set up a custom voltage curve, with that you will have complete control over the voltages.

I own a Strix 1080 ti too and i was thinking about ordering an EK waterblock but i saw that with our card specifically the warranty is getting void if you unscrew the backplate (there is a sticker that voids warranty on top of the screw that u have to tear in order to unscrew the backplate) , is that not the case? Is it worth it? One of my friends has LCed his Aorus 1080ti and we don't have that huge of a difference in temps like 15 C or smthing like that.
