kymag1c22Yes, only been using the 2 cables because this photoand because my PSU only came with 2 pcie cables so that was my only option, it's the ssr-750fx model. Either way, I will reply back once I have the 3rd cable next week. Thanks!
HammajangdFunny, I actually ended up purchasing The 1000w g3 cause I figured better to be higher on the W lol
jankersonReckoner223I 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.

ngauglerHammajangdFunny, I actually ended up purchasing The 1000w g3 cause I figured better to be higher on the W lolThey 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.
LimitinI'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?
BizmanizRead 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 TomahawkRyzen 7 3700X3080 FTW3 UltraCrucial Ballistix 32gb 4x8 PC3600Corsair 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?

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.

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.
BizmanizUpdate: replaced psu with a seasonic 850w titanium. Running a solid 2 hours now, Ran prime95 and Heaven, also played some COD. no issue so far.
arestavoA shut off/restart indicates that the power supply can't handle it, or the video card is being pushed too high (usually overclocking - I've actually had this happen on my 3090 FTW3). Test in another computer (friends/repair shop), test a different power supply. If you cannot do either, RMA the card. If the problems persist, RMA the power supply.
arkarsenal85I just bought a EVGA GA 850w PSU just over a month ago and hearing that it's having issues with a 3080 has me concerned. Like, am I screwed? I can't return it. I don't have a 3080 yet, but once I do, what am I supposed to do if I get random restarts? Just chalk it up as a loss? That seems preposterous for a product I paid over $200 CAD for and is less than 2 months old.
WraithDecayEVGA 750GA All 3 separate cables.
vexorian87WraithDecayEVGA 750GA All 3 separate cables.This might be your problem? My 3090 FTW3 Ultra is currently pulling 486w playing RDR2. I haven't measured total system draw yet but it has to be well over 800w with my 9900k and other misc devices. Your system draw might be spiking closer to that PSUs limit than it likes.
