SuperNOVA 1050 GS – Overshoot Transient Tests
VSB On VSB to 100%, 12V Off to 100%, 12V
O-Scope Shot O-Scope Shot O-Scope Shot

Our power on transient shots for today look much like the ones we saw in the 850 GS review. Not the best ever in the history of our sport, but more than good enough to get the pass. No issues at all.

Hot box time! It’s a bit warm in the lab today because I still have two cryptocurrency mining machines running in here, so I’ll turn on the one exhaust fan and see if we get to fifty degrees. I’m not worried about this unit… if it gets too hot, it has overtemp protection.

* Fanless operation.

Ah yes, an easy pass for Gold again at up to forty-five degrees. It drew even further away from Platinum than it did cold, but that’s to be expected. The hot box often does that to units. Again, because I could see the fan this time, asterisks tell you where the unit ran without active cooling.

But those voltage readings… great chocolate covered pretzels! This time, we have 0.3% on the 3.3V rail, the 5V rail didn’t move at all at 0%, and even the 12V rail couldn’t be bothered to do worse than a shockingly good 0.1%. The average number for the scoring page is just 0.13%. It’s darn near perfect. My memory tells me that’s the best number I’ve ever gotten as far as stability goes. Heck, the 5V rail didn’t even move in the crossload tests, a feat rarely accomplished at this site.

Let’s see if the ripple suppression is anywhere near as good as these numbers are.

Well… no, not quite. Oh, we have excellent results here, make no mistake about that. The 12V rail is at about 25mV, and the minor rails are under 15mV, but I have seen the competition in Antec’s high-end Delta builds do better than this. Super Flower’s also been going for the throat here, too.

But I’m not complaining. Excellent is excellent. Let’s take some stuff apart now.
