x750 making random clicking noises + Low 3.3 reading.

post #1 of 2
Thread Starter 
Well, my initial reason I looked into my psu is that it is starting to click. Not a click like a fan hitting something, more like a mechanical relay/switch engaging very quickly multiple times. It happens randomly both at idle and load, and it can happen anywhere from 1-3 times lasting a second, to 5-10 times lasting several seconds.

After looking into this a bit more I decided to check my voltages in my bios.

12v reads 12.096 which is fine, 5v reads 5.00 which is perfect, but 3.3v reads 3.056 and bounces to 3.072 and back several times every minute.

The psu is a little under a year old, I would assume the clicking/low reading on the 3.3 would be sufficient cause for concern for me to RMA right?

It sounds like there is the possibility that your psu is starting to go bad, as in hearing sounds from it while idling is not a good sign.

However, you cannot really rely on bios or software voltage reading to get accurate readings of your voltages, you really need a psu tester to do that as anything else is unreliable.

I know my psu was reading about 11v on the 12v rail with my old socket 775 mobo in the bios, but after physically testing it, it was well above 12v.

I would put in an RMA ticket and see what they say.
