View Full Version : PC power supply as 12V source?

07-23-2001, 08:58 PM
Hi there,

I am trying to use the PC power supply as a source of 12V supply, for I need its high current (about 8A). However, all the PC PSs I could come by didn't give me the 12V. The highest goes up to 11.5V which is not enough to power my stuff. I was wondering whether all PC PSs are like this (providing lower than 12V voltage) or I am just unlucky? http://www.PCGuide.com/ubb/frown.gif

Thanks a lot.

Power supply voltage range is:

Yellow +12V = +8.5V - +12.6V
Blue -12V = -8.5V - -12.6V
Red +5V = +2.4V - +5.2V
White -5V = -4.5V - -5.4V

So the voltages you saw on the power supplies you checked were within acceptible operating range, while actually lower than the 12V it's usually referred to.

YOU! Out of the gene pool!
