We come once again to the load testing stuff. As always, a FastAuto load tester will be doing the loading, with the rest of the usual test gear getting the readings.

|Test #||+5VSB||DC Watts/
First, as always, the standby tests. We have some excellent looking readings here in the voltage column, with the unit measuring at 1% load regulation on the nose.
Efficiency is much better than average in tests one and two, but still well on the right side of the average line on test three. I’m pleased with this.
Let’s see how the rest of the load testing goes. Remember, I did change the scoring slightly and we now are incorporating crossload numbers into the voltage regulation.

* Fanless operation.
First up, I have some really good news for those who like efficiency… this thing is actually 80 Plus Platinum. Test five is a big stretch, requiring all of my 1% error margin allowance to clear it, but it does get there. And it operates fanless up to test four, too, though it never turned off for the first crossload test as these units sometimes do.
Unfortunately, the unit wasn’t quite as good as the box led us to believe on regulation, at least on the 3.3V rail. That one works out to 2.70%, which is a strictly average looking number to me. However, the other two rails do make up for that with the 5V managing 1.20% and the 12V doing 0.83%. That works out to a three output average of 1.58%, which fortunately puts it on the right side of the box promises for scoring later. I wish the 3.3V output had better load regulation than it does, but this is not a deal breaker.
And no, I could not hear the fan. I have no way to measure how loud they are, so that mere observation is going to have to suffice.
