Question Possibly Broken PSU

[rkegan]

Hey everyone,

First post here I'm just trying to figure out what is wrong with my PC. Whenever I hit my GPU with a load, my computer shuts off and I don't know if this is a PSU or GPU issue. I have tested my CPU (R2600X @ 4.25GHz 1.45V) with Prime95 and it pulls about 150W with no issue, but when I run FurMark or run a heavier game, I shut down. Any ideas on what could be wrong before I go down the rabbit hole of RMA-ing both? I have an RTX 3060ti (ran at both stock 200W and an undervolted 160W) and the system is fully hand-built. I was doing stuff yesterday just fine but today it shuts down. I have been running my PC like this for over a year with no stability issues, any help is very much appreciated!

The PSU is an EVGA SuperNova 650 G3 that I have had since Jan 2019.

Thanks
R

Generally, there are three issues with sudden shutdowns.

60% - Heat " CPU, GPU, RAM, m.2, VRMs"
38% - Driver/ Firmware issues that control and monitor heat/voltages
2% - Hardware fault

What are your temps under load? Have you had any recent driver/Firmware updates recently?

If it totally shuts off then possibly PSU issue.
