I have a very strange problem with my desktop. It instantaneously and randomly shuts down when I am playing certain games, but nothing happens when other tasks are running--even intensive ones like Blender. Now, since the first day I built it, my CPU has always recorded extremely high temperatures. I figured that the sensors were broken, as I had carefully installed the cooler (Intel stock) and never had any problems even as the recorded temperature reached over 120 C for over a year. Yesterday, I changed the thermal compound on my heat sink and the idle temperature (which usually sat at 65 C) went down to 35 C. However, even after reapplying the thermal paste and reseating the cooler, these problems persist. Should I cut my losses and buy a new CPU? Might there be RAM corruption that certain games are sensitive to? Should I have my PSU tested?
It's probably the PSU, mine is encountering issues similar to yours.
Memory diagnostic returned no issues. Turning off speedstep and setting the system cooling to active seems to have exacerbated the problem, leading me to believe that my PSU really is failing.
What's the make and model of your PSU?

Corsair HX850. It is way above the power requirements for my computer. GTX 780, i5 4570.
Ah, a CWT made model. Honestly not too surprising if that is the culprit.
I just did a little research into that manufacturer. I guess I'll get another brand or make to replace it with. I've heard good things about Antec, Sea Sonic, and Cooler Master; not sure about Rosewill.
What do you think would be a reliable replacement? I use my PC as a render station, so I need something that will be able to run for days at a time under a heavy load.
This would do an excellent job.

Before replacing the PSU it's probably a good idea to cover all the basics first to rule them out, it'd be pointless you spending out money only to find it doesn't resolve the issue. How long have you had the system? There's a possibility the PSU itself is still under warranty. Channelwell whilst of course far from the best of the bunch is still perfectly capable of producing PSU's that do what they say on the tin, in most cases the negativity they receive is unjustified.
Have you checked in Windows Event Viewer (for example) to see if there is more information relating to the shut down? Have you verified your drivers are not corrupt by a clean reinstall? What are your GPU temps? You could also download memtest86 and plop that on to a USB and run it at next boot, to try and rule the RAM out as being a cause (although you say you did this, you didn't state what with - if it was with memtest I guess you can disregard this).

I've had the computer for between a year-and-a-half to two years. GPU temps have never gone above 60 C. I have a "supercooled" (two fans, very large copper heat sink) EVGA GTX 780. I always do a clean install or run a cleaner whenever I install new drivers.
I already checked Event Viewer, and it provided no useful information. There are no events that could have any causal links to the shutdowns.
I'm not going to jump the gun and buy a new PSU yet. I'll take my computer over to a local tech place and switch it out to see if there's any difference.
I just used the Windows memory diagnostic tool because I don't have a thumb drive or spare discs around right now.

I know that the Windows diagnostic tool isn't nearly as comprehensive as something that must be booted, but I can just switch out the RAM sticks when I go to the repair place, too.

You can test your rap without software. Just remove all sticks except one and test your system.
If it still crashes, switch it out with another stick and repeat.
