Are you SURE its not overheating?

"Like 50C" is not very accurate.

Check your even log after your PC shut down. You are looking for a red alert icon.

Where to find :

Control panel > Administrative tools > Event viewer > Windows Log Tab > System Tab.

Also if you have an extra power supply. Swap out yours, usually this sort of issue is either cause by overheating or a faulty PSU.
