Good stuff, those Ultra power supply testers.
I've got this one....... http://www.performance-pcs.com/catal...oducts_id=2237
Never do a build without using it. Might get the newer one too.
For those of you that are new to building your own systems.
This is a very good thing to have and use, even if it's a new power supply! Test it.
I've had 2 power supplys that were bad and caused untold damage after shorting out.
