[QUOTE="Crazy_Eddy, post: 21729, member: 167"] Hmm.. I'm not too sure. One thing I do know is, if your board does not use the additional 4-pin +12v connector from your PSU, then it means your CPU is being powered off the 5v rail. In fact, since your 12v shows a higher voltage, it all the more confirms that your 12v line isnt the one being loaded. A quick run of any tool like Prime95 etc will maximise power draw, and your 5v line voltage will drop on an AthlonXP system, while the 12v line will rise. Reason being any line thats loaded shows a voltage drop when massive power is drawn. The feedback circuitry in your PSU steps up the voltage output, so that the loaded 5v line doesnt dip too low and this results in your other unloaded line (your 12v line in this case) showing a voltage increase. I myself have an AthlonXP system and can confirm this :) [/QUOTE]
