Before we move on to the hot box, let’s look for power on spikes in the 5VSB and 12V outputs when we ask for full power all at once. And… there’s one, right there. And another one. And another one.

All three of these shots show power on spikes above mean value, but the good news is the 12V side of things is not out of spec. The spike hits 12.5V there, which is well within the 10% limit imposed by the ATX spec. However, the same cannot be said for the 5VSB rail, which hit 5.6V. That’s not as bad as we saw last time with the Xigmatek, and I don’t believe this is dangerous to hardware, but even so… I saw it, so I have to score it.

Hot box time! Since this unit is only rated to forty degrees, I’ll turn on all the hot box fans and we’ll see where we end up. The box claims overtemp protection, so if it gets too hot it should shut down. And if it does that before forty, we get to knock off a bunch of scoring points!

And there we go – forty-two degrees with no shutdowns. Nice.

Also nice was the fact that the unit still did Bronze efficiency in the hot box. With the voltage regulation we had during the cold test, I wasn’t sure it would. That said, with the regulation issues being caused by connector and wiring issues it’s not really something we can blame the electronics for.

Speaking of which, once again we see by the voltage readings that the connector issue has reared its ugly head. The 3.3V rail is now less stable than before, sliding to a mediocre 4.6%. We now get 2.8% for the 5V rail, which is decidedly average. And on the 12V rail, we see 1.8%. Well… at least the 12V rail improved. Meantime, the average stability number for scoring on later is now 3.1%. Still very much average in the grand scheme of things.

Let’s get this page done with… time to look at ripple suppression.

That’s a bit surprising, honestly. I see under 25mV for the two minor rails on all tests. Nice!

However, the 12V has some things going on we need to talk about. In test five, the 12V rail was actually good enough to call excellent. I saw 30mV there. However, that rail wasn’t nearly as well controlled in test CL1 or the low load test, where it produced these oddball ripple spikes that reach to 40mV. Because of those, I’m going to have to call this unit very good on the 12V rail, and not excellent.

The unit’s still pretty good here, though. Certainly better than I was expecting based on the voltage readings.

Let’s take it apart now.
