Do I officially have a PSU problem now?

post #1 of 10
Thread Starter 
This just happened. I got home turned on my PC and it started up then shut off and restarted on its own, and then booted to windows normally. The PC did also shut off on its own last sat just sitting at idle for about an hour. I am going ot replace my PSU but I am still going back and forth as towhat to get. The Corsair HX or AX 850 or the kingswin LZG-1000.

Have you had problems with this PSU in the past?

This almost seems like normal operation. Mine has started up and then shut down right away a few times before, I believe it has something to do with power factor protection (Correct me If I'm wrong).

As far as shutting down when it was in standby, that may be a power saving feature you have enabled in windows.

Then again, if this PSU has troubled you before, it may be time for a replacement.

I checked the power saving options and it is not set to power down for sitting idle for too long. I have only had this PC for a little over 2 weeks, but everyone says my PSU is junk.

Which Coolermaster do you have? The GX750, or some other unit?

The GX750. I am going to get the HX or AX850, not sure yet. I really would like the kingwin LZG-1000 but many say no that is not good or reliable, and RMA'ing with them is horrible.

Oh right, you PMed me, derp.

Your system could run on a quality 450W, and you could run Crossfire with a quality 650W.

Good to know. I really just want to have some room for my system grow and that is the reason for wanting higher power. I will add liquid cooled gpu's and over clocking with extra hdd's

I Agree with the above statement.
And to be clear, you disabled monitor sleep mode and hard drive standby. I am almost possitive these settings come default enabled in Win 7. I have seen frequent complaints of systems not recovering properly from this.

Ya it is not set to sleep or power down. I cant really see any other settings in the power section of the control panel. Just the one to turn the screen off and put the PC into sleep mode. Nothing there about powering down after time that I can see.

Anther suggestion you might try is to turn your system on and enter BIOS and just let it sit there for an hour or 2 and see if it turns off. Or you might try loading in Safe Mode and see if it turns off.
A bad power supply is certainly possible but many things can cause this. Heat, Software Corruption,
Drivers, Virus, Other Hardware Components, etc.
