Matt3232 Posted January 25, 2009 Share Posted January 25, 2009 Hello, I ran into a problem this week where my computer would shut down without warning. On a hunch I jumpered the 24 pin connector of my power supply and measured the voltages using a multimeter. The 12v and 5v rails were ok, but the 3.3v line only measured as 2.74v:confused:. This value drops to about 2.69v when the computer is on. Is this normal or is my power suppy faulty? Thanks, Matt Link to comment Share on other sites More sharing options...
FEAR6655 Posted January 25, 2009 Share Posted January 25, 2009 That is too low for the 3.3v. What does the BIOS say the voltage reading is? If that says the same then the power supply is probably faulty. Link to comment Share on other sites More sharing options...
Matt3232 Posted January 25, 2009 Author Share Posted January 25, 2009 Here's a picture of HWMonitor(It reads the same as my BIOS, I checked.) http://img150.imageshack.us/img150/532/capturejy0.png Ignore the fact that the 12v and 5v voltages are reading really high, I have confirmed otherwise with my multimeter. I also found a few other threads on here describing the same problem of shutdowns, especially during gaming which is when I have the problem too. There's also a thread about a problem where the computer will not boot properly after a shutdown if you don't wait 20 seconds or so before powering it on; I also have this problem so I'm pretty sure the PSU is defective.

FEAR6655 Posted January 26, 2009 Share Posted January 26, 2009 I would say the same. Link to comment Share on other sites More sharing options...
Matt3232 Posted January 26, 2009 Author Share Posted January 26, 2009 I think the motherboard might be tripping the overvoltage protection on the PSU because of those high voltage readings, causing the shutdowns. Regardless, something's wrong with that 3.3v rail so I'll see if I can get the PSU replaced first. Link to comment Share on other sites More sharing options...

And I'd take your voltmeter readings as gospel well before I'd believe the BIOS readings. Link to comment Share on other sites More sharing options...
