|VSB On||VSB to 100%, 12V||Off to 100%, 12V|
Well, we start off looking good with the first test. However, both shots on the 12V side are definitely not what you would call smooth and continuous. That’s going to cost them a little when it comes time to score this thing.
Let’s get the second round of testing going.

Ok, we’re starting with the load regulation first. On the +3.3V rail, we end up with the same 1.0% as we had in cold testing. On the +5V rail, we have a slight increase to 1.32%. The +12V rail stays unchanged at 0.08%. Lastly, we have the +5VSB rail increasing to 2.14%.
On the efficiency side of the scale, we need to achieve 90%, 92%, and 89% at 20%, 50%, and 100% loads. At the 20% mark in Test 2, we hit 90.5%. At 50% load in Test 4, we hit 92.48%. Lastly, at 100% load in Test 8, we hit 89.94%. We have a clean pass for 80PLUS Platinum certification.
Utilizing a hot-box setup as we do, it becomes a challenge trying to heat up some of these very efficient power supplies. This unit, for example, managed to hit 22°C in/26°C ex in the cold tests and 38°C in/36°C ex here in the hot tests.
Looking at the fans RPMs, we can see the increased heat did cause the fan to spin a little more.

Looking at these rippletastic shots, there’s not really a whole lot that can be said. The +3.3V and +5V rails came in at 5 mV & 6 mV. The +12V rail came in at 22 mV, while the +5VSB shows 15 mV.
Shall we crack things open?
