End of last year i have smoked a new ultra prima titanium 1000w in 3 weeks. Benching a single newly bought 2080ti for fun. Same issue.
I got my money back and was only able to find the new TX series in stock to buy as a replacement.
So far so good.

I really don't think it's his power supply specifically. I have a seasonic 750w which is a quality brand but it's also shutting down. It's evident that a 750w PSU isn't enough for both the 9900k and 3080.

Certain PSU models can't handle the transient power spikes of the 3080's and 3090's.
 
Even some 850W units are shutting down....
 
We know the EVGA GA and some Seasonic Primes and Focus also shut down.
 
The ones we know work are, so far:
 
EVGA G2, P2, T2;
 
Corsair RMX, RMI, HX, and HXI.
 
 

I have an evga 750gq but i dont have my xc3 ultra yet. Are there any problems with that model?

 
I saw one 850W GQ that was working so far so you might be OK.

I'm having an issue with a 3090 FE and an EVGA GA 850W PSU. Start trying to play a game and hear a click and the PC turns off with only the RAM illuminated with rgb still. The computer doesn't turn on again until I toggle the switch on the PSU.

Do I need a new PSU?

Funny, I actually ended up purchasing The 1000w g3 cause I figured better to be higher on the W lol

They say you want to run the PSU at 50% for optimal performance.  400W for a GPU (3080 FTW3 Ultra current max) and 120W for a 9700/10700k and you're there.  Who knows where you'll be in 3 years, maybe with a i9 or a #090 Ti.  Ideally my PSU / case will live through a hardware refresh or two.

Yup! I’m running a i7-10700k right now but using my ancient 1050ti. Can’t wait to get this 3080.

I have that same psu. And from what I have read and researched it won’t work. I just ordered a new one to be safe

Read through all of these, throwing in my $.02 since most said RM850x should be good to go. Not the case if refurb'd, I think.
 
Got my 3080 FTW3 Ultra AND a refurb'd RM850x on the same day. Installed, everything ran fine for 6-7 hours. Next day, random PC shutdowns and PSU trips (have to flip the switch off and on to reboot). I'm pretty sure it's the PSU since it's refurb'd, but not 100% sure until I replace it and run it. CPU and GPU temps run 60's when playing COD.
 
DDU'd the drivers, reseated the GPU as well as the 4 sticks of 8gb ram (1 first, then the other 3 after reinstall drivers and reboot)
 
Specs:
MSI MAG x570 Tomahawk
Ryzen 7 3700X
3080 FTW3 Ultra
Crucial Ballistix 32gb 4x8 PC3600
Corsair RM850x (refurb'd)
 
No OC'ing (first PC built since '05), not even playing any games and it will shut down.
 
If not the PSU, what else could it be?

Well I hope its just because its a refurb because I have that exact PSU.  I just bought it like 2 months ago.  Mine is brand new though not a refurb.  I will be so pissed if it doesn't work when I eventually get my 3080.
 
What do you plan on replacing it with?
 
Well good luck hope you get it figured out.

Just thought to replace my white modcables with the stock cables, could be those too but we'll see. I'm not sure what I'm going to go with, I'll see what they have in the store tomorrow. I know they have some RM850's (non x) so I might grab that if they don't have a 1000 watt.

Everyone I asked said the stock cables just provide better ripple protection because of the built in Caps.  They also said it wouldn't be a big enough difference to worry about but who knows with the 3080s.  These cards are starting to look pretty picky about their PSUs.
 
 

Just wanted to add my input because I just installed a 3080 FTW3 Ultra last night and everything worked out of the box. DDU'd everything first since I was coming from a 5700XT. Downloaded latest drivers straight from Nvidia. Downloaded PX1 and everything works so far. I haven't been able to check the OSD since it does say only for certain games. No overclock or undervolting yet. Just straight out of the box, installed, then played for an hour and a half of Warzone and Black Ops, everything ultra/high and enabled at 2k, min / max FPS between 130s to 170s. Sorry, not really concrete numbers, I was too excited to start gaming with it.
I received one crash error, but I was playing Black Ops Beta when it happened, so I'm not sure. But it only closed the game, no shut down or black screen. No power issues otherwise with a two year old Seasonic Prime PSU.
 
 
Specs: (everything bought at the beginning of this year if that matters)
Asus Prime X570 Pro
AMD Ryzen 7 3700X (No OC)
G.Skill Trident Z 32gb (2x16) 3600
2x Corsair MP600 1tb NVME SSDs
Seasonic Prime 1300W Gold (bought in 2018)
 
 
P.S. I don't believe that certain brands of PSU can handle these cards any better than a competitor. You-get-what-you-pay-for, sure, but so far all the issues seem to come from those with a little bit of headroom power-wise from the recommendation of Nvidia (750W). So certain brands might be able to regulate better than others given the low headroom. I do believe that a large overhead is needed for these cards. That's just my personal opinion. I emailed Seasonic about the issues I've seen on these forums and they assured me that my PSU can handle the power spikes of these new 3000 series cards. They didn't say what the floor output should be though, so I took that with some grain of salt. I'm also using generic braided cables from Asiahorse, connecting three completely separate power cables from the PSU to the GPU for the three power connectors. Everything worked fine last night. Time will tell if everything continues to work smoothly (fingers crossed). Going to put a little core and mem boost tonight and adjust the voltage curve, we'll see what happens.
