Summary: I saw the good reviews for this unit as well as the bad reviews regarding noise/the high pitched coil whine, and figured any issues this PSU may have had would be fixed by now. I was wrong. Got everything plugged in and turned on, and holy crap it's a sharp noise. I mean maybe if it was in a cabinet hidden away 20ft it would be okay, but as it is the machine is sitting 10ft away on the ground next to my desk and it's annoying as @$#%!
Summary: Really disappointed with both this and the EA-430D that I tried. Both emitted a high pitch whine that I found intolerable. Returned both and got a Seasonic S12, which does not emit a high pitch whine, but is louder overall. Other Antec power supplies I've had in the past have been rock solid and very quiet. Antec probably figured they could save some money and found a cheaper supplier, or lowered their spec.
