Pc Shuts off randomly

[chexmixqueen]

My PC shuts off randomly like I kicked the power cord, no warning just nothing. I have ran many memtests to make sure that wasn't an issue and my RAM passed all of them. It happens during all kinds of different things but I can only replicate it consistently while rendering with Cinema4D (CPU rendering if that helps at all.) It also happens mid-boot cycle sometimes as well. I will list my specs below but I cannot find an answer for this online at all so I thought I'd try here. Thanks my friends.

 

SPEC LIST:

CPU: Ryzen 3700x cooled by an Arctic Liquid Freezer AIO

GPU: RX590 Sapphire

MOBO: Aorus PRO B550M

MEM: 16gb Corsair Vengeance 3000mhz

PSU: Fractal Design Ion+ 660p

HDD: 2tb Seagate Barracuda

SSD: Samsung 860 500gb

possibly a PSU issue?  Make sure all your cables are fully seated / secured?

Do you have another PSU you could test with?  a 500W should be fine for testing

Sadly, I don't. I should be FAR under the wattage limit but is there something else that could be going wrong with the PSU to cause this? Could I be overvolting my MOBO as well?
