Loki,
I'm no specialist in electrics, but IIRC you must look for the _combined Power_
ratings and the ampere per power rail (3.3, 5, 12 Volt).
You can appr. calculate your needs here:

http://www.journeysystems.com/?power_supply_calculator

It's a bit outdated, but they're in the process of updating the calc. for more
modern components. But it still works. And if your bits 'n pieces are not included,
you can replace your current hardware pieces with others in the list , equalling
appr.
your power useage to calculate what you need.

Other than this, I don't really know how to test if a PSU is faulty i.e.
I'm no electrician/electronician.

Raphael ;)
