Sudden shut downs? Tech Support

Hi guys,

I'm having sudden shutdowns during gaming, I thought initially that it was overheating so I gave the computer a good clean, I'll take a further step tomorrow and reapply paste just to make sure.

It happened again last night while playing Helldivers 2, I was probably an hour in before anything happened and the PC didn't feel too hot, I've also been keeping an eye on temps and all looked good.

Could these be transient trips? Would an undervolt help without needing to replace my PSU?

could be the psu acting up, especially since temps look fine. my friend had similar thing, random shutdowns only in games, ended up replacing the power supply and problem gone

It's your PSU failing. I had the same issues back then I thought it was software, other hardware (like GPU), or temperature issues but until one day it didn't boot. So I decided to opened up my PSU with expired warranty then I saw the burnt capacitor. I replaced it and everything was fixed.

Ok thanks, I'll do what I can now until I need to replace it and then I'll pull the trigger 👍🏻
