Hello everyone!

My computer today has started shutting off (not restarting) after playing games for 5-15 minutes. I have no idea what could be causing this. Nothing has changed since yesterday and it was working fine yesterday. My rig is

AMD FX 8350
Nvidia GTX 660
G-Skill 8 GB RAM
Corsair 120 SSD
Samsung EVO ssd
Coolermaster PSU

Is my power supply dying? (it's about 3 years old). My temps have been slightly high but not within the dangerous range I don't think (CPU: 51C and GPU: 66C). What could be the problem?

Thanks for your help!

That Cooler Master eXtreme Power RP-550-PCAR W/O PFC is made by Seventeam.

If you look at the past history of Cooler Master PSUs that have Seventeam as the OEM you will see that they are essentially garbage. They usually can't deliver the power specified on their label or they burn out when attempting to do so.

I would say that you're running at pretty close to or have exceeded the maximum limit of that PSU's maximum combined +12V rail capacity.

If it's suddenly shutting off without warning it could be temp related, check your BIOS to see if there's a temperature shutdown option.

You could try forcing this outside of a game so you can see temps live, try running Furmark on your GPU to see if that causes errors and to check live temps, you can also test your CPU with something like OCCT or Prime95, and use Cortemp to watch temps climb.

Also, check the System event log to see if there are any events logged prior to shutdown that may indicate an error.

51C for CPU and 66C for GPU is damn good temps for under load. I don't think its a temp related issue.
Check if one of the GPU's external power connector is coming lose otherwise it does seems like a psu issue to me.

don't really have a particular budget range or preferred vendors. I was wondering what sorts of options I have. I want a good quality PSU that will last a good amount of time and still provide enough power for upgrades in the future.

Thanks!

Any plans for SLI or CrossFire graphics cards in the future? If yes, which graphics card model(s)?
