3.3v rail in BIOS is RED and reads only 2.88v

post #1 of 5
Thread Starter 
im not sure what components run off the 3.3v rail but mine happens to be in red and .4v under what its suppose to be. can this cause computer to BSOD randomly? especially when over clocking? is this something to be worried about? FYI i just buildt a my computer and have a 1 month old CORSAIR TX750w power. bought it BRAND NEW. thanks so much guys!

Someone correct me, but I think only fans run on the 3.3? Several years back almost all critical components were on the 3.3 rail, but they all use the 12v now. I don't know of anything other than the fans. HDDs and DVDs have both 3.3v and 12v inputs however.

Ignore software or BIOS PSU monitoring as it is inaccurate.

If it was that low your RAM wouldn't function. Since your computer turns on, it's clear the reading is inaccurate.
