Games are turning off PC on launch

[ripper101]

Hello, I have been dealing with an issue recently on my PC where when I run intensive games my entire system just shuts off instantly and reboots. At first it was pretty inconsistent but now it's crashing right when getting in game. The worst offender is Star Citizen and I am able to play low intensive games without any issue. I can play League of Legends or Minecraft without any issues. I have most software things ruled out such as latest BOIS (even trying latest beta BIOS), drivers, and updates. It's a relatively fresh install of Windows 11 pro and I haven't installed anything new recently. I have also tried out of my 4 sticks of RAM, 2 sticks, 1 stick, and the issue still persists. I thought it was my RAM so I bought a new kit and the issue still persisted. 

 

So my next thought is the power supply but I am unsure. I have been running this setup fine for a year without any issues so I think 750w is enough. This started about a week ago and the issue is progressing. I was able to play Star Citizen for a few hours now it crashes right when It's done loading and I get in game

tbh id go with a 850W minimum with the rtx 3080. You said that the entire system shuts off with the intensive games right? well RTX 3000 is known for its 600W ALONE transient spikes of power that will trip a PSU's overcurrent protection/

Power hungry CPU+GPU and 750W PSU = This problem.

Yes but what doesn't make sense to me is I used this system without fault for a year and have made no hardware changes. Has something in the PSU degraded?

Well a PSU running at 50-70% capacity will last longer than a psu thats at 80-90% capacity....also the PSU tripping itself and shutting down, along with the gpu spikes can sevearly limit its lifespan

So just another 100w will do the trick?

I would just grab a 1000W seeing as GPUs aren't going to use less power anytime soon by the looks of things.

@GuiltySpark_ I saw you mention the powersupply I am running? Should I RMA it? 

I am also running 3 monitors and no overclocks

Maybe. 

 

One of if not the best SFX PSU's you can buy and can easily handle that setup you're running. Has for me for nearly two years w/ a 5800x/3090, both overclocked. Its a shame people just see the rated power output and immediately jump to "NOT ENOUGH" without doing any research. 

 

No product is infallible, however, and things can be faulty.

 

Power limit the card to say 80% in Afterburner and try the same games again?

well I tried the 80% limit and it turned off instantly still. Kinda don't know what to do now.
