Solved PC randomly shuts down

September 27, 2017 at 16:35:15
Specs: Windows 10
This started happening all of a sudden, maybe 5 minutes after boot the PC completely shuts down without warning. I assumed this was a PSU issue but I could turn the computer on straight after. I monitored the usage in task manager and temperatures before it directly shut down again and there was no spike in any department. Specs are AMD FX8350, GTX 970, 12GB RAM, 1200W PSU

"Cheap brand PSU, only to get me through temporarily. Thought higher wattage would mean increased durability."

You thought wrong. I don't know if you're in the US but Newegg constantly has Corsair PSUs on sale. For example, here's a 550W for just $25 after promo code & rebate. It will more than handle your setup.

"Temperature stable around 65-70°C on CPU"

According to AMD, the max safe temp is 61C, so I suspect you have a problem with your CPU cooler or thermal paste application. The temp at idle should be in the 30s.

The standard stuff first: Have you cleaned the vents/fans/anything that would prevent good airflow?

You mention a 1200W PSU. Make? Model?

Yes, what make and model?
What temps are you showing? CPU, Chipset (MB), HD, GPU, etc. (Use HWMonitor to read).

You have to be a little bit crazy to keep you from going insane.

did you overclock your CPU and/or RAM?
xmp ram profile is also considered an overclock

Simple solutions are often the best

Cheap brand PSU, only to get me through temporarily. Thought higher wattage would mean increased durability. Temperature stable around 65-70°C on CPU, GPU about the same. Only seems to happen when using power-hungry applications like "The Witcher 3". Happens only whenever I've played this game.

A manufacturer could claim 1.21 jigawatts and it still wouldn't mean jack as far as reliability is concerned. As riider mentions, stick with well-known and well-reviewed equipment if you do any amount of gaming.
