Make sure you get the PS-224 and not the PS-124. The PS-124 only has LED's that tell you a line is live.
This gizmo activates the PSU and gives you voltages. It even gives you the voltage and delay of the power good signal.
Not even a computer shop in Phoenix is going to tell you more because they'll probably just use the same kind of device and charge you labor. The next best thing is a load tester, but usually mom and pop computer shops don't have load testers (99.999% of the time). So unless you've got a buddy that works at BFG, PC Power or Corsair or something that can put your PSU's on a load tester as a favor... get the Coolmax tester.
