dmnt Posted September 22, 2007 Share Posted September 22, 2007 I installed my HX520W and was immediately alerted of an issue in the hardware monitor in the BIOS. The hardware monitor was displaying this: VCORE Voltage 1.72V +3.3V Voltage 3.48V +5V Voltage 4.94V +12V Voltage 12.16V -12V Voltage -11.88V -5V Voltage [color="Red"]-6.14V[/color] I disconnected all devices other than the motherboard to confirm that it wasn't an issue with one of my peripherals. The hardware monitor was displaying the same readings. This had never happened with my old PSU. I'm concerned that -6.14V may damage my machine. Is this normal? Is it safe to operate at that voltage, or is there something wrong with my PSU? TIA Link to comment Share on other sites More sharing options...
EliteKiller Posted September 22, 2007 Share Posted September 22, 2007 Your 3.3V is also out of spec, however you should use a digital multi-meter to measure the voltages. You can pick up a nice one from Sears or Radio Shack for under $30. Link to comment Share on other sites More sharing options...

dmnt Posted September 22, 2007 Author Share Posted September 22, 2007 http://forums.extremeoverclocking.com/showthread.php?t=137886 I just measured the 12 and 5 volt rails. I get 12.04 and 5.01 respectively, which is good. I don't have an aux cable. How do I measure 3.3? EDIT: Nevermind, I used the ATX connector. Its fluctuating between 3.40 and 3.41. Everything is cool. It was the BIOS that was wrong. Thanks for your help! Link to comment Share on other sites More sharing options...
EliteKiller Posted September 23, 2007 Share Posted September 23, 2007 You're most welcome. It's a shame that your bios voltage readings are so far off. Regardless, I'm glad that you had a DMM and could verify the voltages the proper way. At least when someone else down the road has a similar issue you can point them to this thread. :headbang: Link to comment Share on other sites More sharing options...
