Hey guys!

I've been having a strange problem with the z370 ITX board and my M.2 drive. Basically everything usually works fine, however I'll randomly power on the machine and immediately notice a drastically slowed down M.2 drive. This is evident both in boot times and SSD diagnostic tools. The SSD basically will run at 1/100th the speed. I can remedy this by fully powering off the machine and powering back on. 

Any idea what could be causing this? I was thinking it may be a weak PSU (450W) but I don't know if that makes much sense.

Specs below:

CPU: I5 8600k (overclocked to 4.2)
SSD: Samsung 960 EVO M.2
RAM: CORSAIR DDR4 M VENGEANCE LPX DDR4-3000
GPU: Nvidia GTX 1080
PSU: ST45SF ??G
