Now, we come to the load testing. Because this is a smaller unit, I’ll be testing as a single 12V unit. I can go dual or quad, but because the FastAuto load tester can handle so much power it won’t heat the hot box up enough later.

Otherwise, the rest of the usual test gear will be in use again.

First, the standby load tests. Efficiency is all over the map, here, though always above what I consider average for the standby section of these things.

Voltage regulation is an excellent 1% on the nose. I hope this is a trend that continues.

Fortunately, there’s a trend that has not continued from the MaxBron unit. That one had all kinds of incidental issues normally not seen during load testing, like power good running out of spec. No such issues were found this time. This unit just ran like it was supposed to until I shut it down myself.

Voltage regulation on this unit comes in at 1.3% for the 3.3V rail, 0.8% on the 5V rail, and 1.83% on the 12V rail. This makes for an excellent 1.31% average, which is itself an improvement on old Max though not much of one. But that’s ok, we don’t need mythic level regulation at this price point, nor should we expect it. These numbers already represent what used to be state of the art not so long ago.

Efficiency, for a Bronze unit, was astounding at low loads. This thing tickled 80 Plus Gold for quite a while before dropping off to finally end up at Bronze by full power. I like units like this, because you know they’re not bought primarily for gaming at full power all the time. Usually, they’re found in rigs where the owners can’t afford that second video card yet but would like headroom in case they go ahead with it someday. This unit, with a single decent midrange video card, will hum along at 88% efficiency until Bob in Dallas can finally afford that second card. By that time, he will have likely gotten his money’s worth out of this thing.

Is the fan loud? Is the fan quiet? I keep telling y’all I have no idea… the load tester fans are too loud. Five screaming 120mm 120VAC fans all in one box? Yeah, I’m lucky if I can turn the office TV up loud enough to hear it over those little monsters.
