"-5.0v Exceeds These Limits"

Obviously the software is reading the 3.3 volt circuit instead of the -5 volt. False alarm.

The only proper way to test the voltages is to use a digital multitester.

Link to PSU specs if that helps http://www.maxpoint.com/products/pow_supp/...fma/details.htm

I don&#39;t think that you even need to test with a multimeter. The software you are using is at fault. Ignore the alarm or even uninstall it and try another program. Or try checking the settings in that software to see if it can be reconfigured.

Thee voltage things don&#39;t make sense to me...

+12 11.97
-12V -12.19

shouldn&#39;t the -12 just be -11.97?

Nope.

They are different circuits with different sources.

If you tried to use the same source then the ground for -12v would be the same as the +12v line, and the ground for +12v would be the same as the -12v line. So the difference between -12v and +12v would still only be 12v, which doesn&#39;t work, it has to be 24v.

Same with +5v and -5v.

Right, lynx. The power suppies use what is called center tapped transformer design.

The Dual Complementary Rectifier Circuit is a combination of two FWCT circuits. This type of rectifier circuit is very commonly used in dual output power supplies, where two outputs are of reversed polarity with a cornmon ground. It is also caued a "center tapped bridge rectifier."
