Hey matt!
This is a general question...maybe a good subject for a guide or something?
I've always been interested to know a little more about system voltages...things like how to test and compare CPU's and the equipment needed to do this...i.e. make sure that components are getting the power they need etc. Also how to test mobo components and the voltages they receive. All that kind of stuff. If you can provide a guide that i can understand then anyone can!
Its pretty hard to test true CPU voltages using electronics, you basically got to trust the MoBo for stuff like that BUT its possible to build yourself a PSU tester that would get its input from an ATX connector and give you lots of benchmarkable info about the PSU. I'll work on some schematics
