Hey all,
 
I have been playing a while with my new rig and had to do a prebuilt PC because there has been no way to get parts nowadays. I have had the PC for about a month gaming and mining while at work. Anyways, while gaming I noticed that I had some artifacts and then my PC just shut off. I am no longer able to game but I am still able to mine (don't kill me) with my gpu when I'm not gaming. Is the 850w psu that came with the prebuilt really causing the issue? Trying to trouble shoot. I can load games and run around for about 30 seconds and then my computer just bricks and restarts. I do have a corsair 1000psu in my other PC downstairs that I do not use. Would this solve the issue? Here is the part list.

• CPU: Intel Core i9 10850K 4.5 GHz
• GPU: EVGA GeForce RTX 3090 FTW3
• Motherboard: ASUS ROG STRIX Z590 E
• RAM: G.Skill TridentZ RGB 32GB DDR4 3200MHz (2x16GB)
• SSD: 1TB Intel 660P M.2 NVMe SSD CPU
• Cooler: EVGA CLC 240mm RGB AIO
• PSU: EVGA 850W 80 Plus Gold PSU

Please no hate.

I've been running the EVGA FTW3 RTX 3090 (w/hybrid kit installed) on a 850W PSU since I got the card in March. No issues. Card even OCs pretty well with that setup.

I'm just wondering if my PSU has seen better days and hit it's limit

I know it’s an 850 EVGA. I have to open the case back up and see. Was reading some of the supernovas we’re having problems. I have a 1000 hx Corsair platinum in another rig. What was weird is that it was performing fine for a few months and I have just now started having issues. Have people been reporting that?

Seasonic 1300w Prime Gold, actually in stock at $250. 
 
EDIT: I've owned this PSU since last year and it could not handle a 3080 Ti FTW3, psu went into protect mode.  It was fine on a 3080 FTW3 XOC.  Sajin has the Plat version and it's fine on a Kingpin. Ymmv.

Seems unlikely it's the PSU, but could be.  Might watch the voltages while it's running something like Kombustor or Furmark.  Just makes it easier to watch GPUZ on the desktop.   I would run DDU and re-install drivers first though.  Then try swapping parts (PSU/GPU) between the other machine you mentioned, if possible.  
 
You haven't changed anything else?  I've seen more than once where someone had tweaked their mobo settings, etc... and actually had an unstable cpu or main mem, but were blaming the GPU since it crashed in a game.

I did change the ram setting to XMP earlier this month. But didn’t have issues until today. Maybe should switch it back and see if that helps too. Will do ddu as well. I underclocked the card to 60% and was able to play flight sim and rdr2 with no issues.

Are you running stock clocks on the card? You said you game and mine. When I mine i drop my core 200 crank my memory 1400 and drop power to 69 (giggity) that gets me 122mh/s on air at 92c. But I load in a different clock for gaming.

Yes I have a stock gaming setting with just 90% fans and then I have a mining setting in afterburner. Last night I did some testing and was able to game a 70% underclock on power.

Before I sold my RTX 3090 I was using an 850 watt Corsair PSU. I upgraded to a 1000 watt PSU so I would have plenty of overhead

I have been reading some articles that the EVGA 850 G+ doesn't deal with changes in watts very well. Maybe the constant change could be causing it some issues

I really don't understand the people who buy PSUs that are marginally enough or with small leeway. Every year of use your PSU will lose a percentage of its effectiveness. Ideally get a big and bad PSU and be happy. It will most likely have platinum efficiency better capacitors, choice between single and multi rail, better fan (usually hydraulic bearing) better build quality and protections.
 
Invest in your PSU and it will be a satisfying experience down the line.

Again it was a prebuilt because it is impossible to get parts these days. The company probably got what they thought was "good enough". I have a corsair hx1000i in my other rig. Thinking about swapping them. Probably would provide a quick idea if it's PSU related.

UPDATE: 
 
Did a memtest86 and found that one of my RAM is faulty. Going to swap out the faulty RAM with some good RAM that I know is working in my other rig. Would explain the artifacts that I was having during games and lock ups randomly. Hopefully this fixes the issues I was having. Would PSU corrupt RAM quickly. Find it hard to believe that my ram would have issues right after purchasing a product but I have been wrong before. 

I helped my BIL upgrade his rig last year- one of the 2 sticks of RAM were bad out of the box. failure in electronics is a thing. unfortunately its more common on prebuilt cause they essentially stock it with parts from the lowers bidder. My other BIL wanted a 3070 or better. he couldn't score so I told him go prebuilt. I didn't recognize over half the component manufacture names. I told him as time goes on to just plan to replace the high risk items if he can get a good deal. 
 
As long as your CPU,PSU and RAM are known name- you should be fine with your set up. 850 is enough for a 3090. unless its from wish.c0n or aliexpress overnight special....

850w psu should be enough, but I mean, if you can afford a 3090, I'd go with a 1000w to have some left over.

it would be sufficient but u might wanna go 1000w (u already spent a lot)

I would get nothing less than 1000w with a Platinum or Titanium rating period. I had a 1000w Gold and it wasn't cutting it with overclocking my 3090 FTW3 Ultra as would restart randomly so I got a 1300w Platinum psu instead.
