In order to load test this unit, I’ll use both load testers today. Because of the forty degree rating on it, there’s pretty well no way to do it with only the main load tester, as it heats up the hot box far too much at this power level. Even with both, we could see higher temps than forty. But that’s for the next page. For now, I’ll fire up the Extech DMM, Rek RF9901, Tektronix TDS-2012B, and dual probe thermometer so we can get stuff done.

Up first is the standby load test chart. Already the unit is looking to make a strong impression, with efficiency over 80% on all three tests. That’s awesome!

And the voltage regulation is equally impressive at 0.8%. Excellent! Let me bring the main power online now.

Holy smokes!!! Do you see what I see? No? Well, here’s what I see: tests one, two, and five cleared Titanium efficiency targets using my current methodology, allowing a 1% margin of error. Test three is the halfway mark, and we missed Titanium there by a mere 0.4%. Folks, this thing didn’t just clear Platinum, it pole vaulted over that target. This is now likely the most efficient 850 watter I have ever tested to date.

And how about those voltage readings – to me, it looks like Andyson is serious about taking on Seasonic and Super Flower. I see 0.6% at 3.3V, 0.4% on the 5V, and 0.3% on the 12V side of things. The average is only 0.43%, which is way better than excellent.

I really don’t have anything much more to say about this. The performance of this unit is amazing. No, I could not hear the fan. Not that it means much… the load tester fans are so loud I doubt I could hear an air raid siren in here. Well, ok, that’s exaggerating it, but my point is the load tester fans are just too loud to gain any meaningful data on power supply fans. Unless those fans can be heard overtop of the load testers’ and that doesn’t happen very often.
