Before we do the old "heat it up and see if it croaks" bit, we'll look at the power on voltage spike tests. And marvel at their near flawlessness. There are no spikes out of spec... in fact, I'll be darned if I see any spikes at all. Rise time looks fantastic as well at less than half the spec. This platform is awesome.

But, we do still need to cook it if we can. I'm locking it into my hot box now and turning off all the extra fans... let's see what happens. I'm going to run it in fully fanned mode this time - not sure I've ever done that with this platform, as sometimes that can cause the unit to miss its 80 Plus target and I try to test them as 80 Plus would have.

EVGA's got these tests handled once again. Forty-four degrees, and it's yawning along like I'm not even trying to hurt it. Awesome.

80 Plus Gold? No problem, even with the fan always running. I never really had much doubt it would do fine, there, as the cold tests were all far enough above the mark that no little fan was going to affect them.

Over in the voltage readings, we again see excellence. We're now at 1.2% for the 3.3V rail, 0.6% for the 5V rail, and 1% on the nose for the 12V rail. That's an average of 0.9%. What more do you want in a power supply?

Oh yeah... you want one with low ripple, too. Let's see what the scope has to say about that.

Ha! Yeah, EVGA's coming out of this with another perfect performance score. You just can't hate this platform... it's amazing. Less than 15mV on all three rails.

Excuse me for a moment. I might need to print these scope shots out and frame them.
