Lizrad :
I was wondering if it was a good power supply and better than the cx750m i returned in exchamge for it.
It's not the best EVGA model. Usually look for GS or G2 rather than NEX. The link below shows a PSU Tier list from Tier 1 to Tier 5...it is suggested/recommended that you stay on the Tier 1/2 side of the list.

Not sure where you're exchanging it, but this one:

The NEX and the corsair CX are a similar level.
