Christ, I wouldn't want any 3080 in my PC if that's how they spike in power.

I'm definetly going to undervolt as well. Been doing it with all the cards I've had over the past few years and have always been pleased with the results.
Interesting thanks...My system is 100% stable the last few days, I'll probably try undervolting to keep power consumption and temps down. I'm definitely not risking the OC bios on my 3080 which pushes the power consumption up by another 50-60W.ive tried two 3090's on my seasonic titanium 750w, i had power issues with both of them, had to give up and stick with a 3080 which has been fine so far, they are so marginal for these new cards though.

That's interesting...cue credits...A troll video from just about the most respected name in the SFF community? There's only one troll here.

I've a similar rig to yours OP (8600k @ 4.8Ghz, 3080 ftw ultra) and I'm running a Seasonic Titanium PX 750W. You have me a little worried now with those figures. Are you running three separate cables from your PSU to your GPU? I'm not, but I don't think it makes a difference as my PSU is single rail.
Can't run three separate cables. Didn't realise the X4 PCI-E connector figure provided by Asus is just two pigtail connectors. Anyway that's how they've designed the PSU.
I wanted to buy 850/860W again, but there were just massive shortages. I was literally losing sleeping thinking my 3080 FTW3 was fragged and got the system going again as fast as possible.
Good PSUs from articles i've read over the years can provide continous power, not just transient above their rating. Obviously this shouldn't be relied on though.
It's kind of too late now.
I think i'll be ok, If I see 800W at the wall as a peak I need to worry... haha
Edit I think I've just pinned down the new noise in my system to the PSU fan bearing. It's not coil whine from the GPU and it's not the fans in the GPU.
It happens when I stress the system for a bit, just as you'd expect a PSU fan to then come on. It's a tally really audible even with headphones on and annoying as rest of system is quiet.
So it may be going back, at least my GPU survived
I was told it wasn’t wise to run a 3080/90 with 1 pigtailed pcie cable and you should always run 2
MY AX860 previously blew, I think it's about 8-9 years old. Roughly equates to 20-25W lost per year owned, at which point my 860 became more like a 650W PSU very roughly.
Im really not sure thats how it works. Especially not to anything like that degree. Your PSU probably had a fault.
A few review sites have re-tested old PSU's and the voltage control etc is sometimes out of spec and some of the readings get a bit sloppy, but they can still chuck out most of the juice.
I think its plausible that the reliable output could have dropped to 800W after 8 or 9 years without a design flaw or unusual failure, 750W seems unlikely, 650W absolutely not.

Do you have a source on these calculations?
