HX650W testing question


Recommended Posts

Hello, I am using a Coomax PSU tester on a brand-new (warranty replacement) HX650W power supply, and the voltages are as following:


+5V = 4.9

+12V1 = 12.0

+3.3V = 3.3

+12V = 12.1

+12V2 = LL (no voltage detected, or below minimum)

5VSB = 4.9


Am I misreading or misunderstanding something, or is my just opened warranty replacement PSU having a problem on its 12v rail? It is replacing a defective PSU, so I hope lightning didn't strike twice - perhaps the HX650W PSU doesn't have a +12V2 voltage, normally?


Thanks for any help you can provide!
