Now… you might be wondering how I intend to load test this unit. OCK on or OCK off. Or Doc Ock ocking the OCK. Well, I’ll tell you. I’m not using this in single 12V mode at all. I do have the ability to load test this unit as a quad 12V model using both load testers, so I will do so. Helping out will be the rest of the usual gang of test gear.

|Test #||+5VSB||DC Watts/
We’ll start off with the standby tests. We see average or above average results on all three of these tests, but nothing really groundbreaking.
Even so, regulation is a respectable 1.8%… I’ll happily take that number all day long from a standby rail, yes I will.

Looking at the main load tests at room temperature, one thing stands out… this unit struggles just a bit with Platinum efficiency in tests two and three. It’s a good thing I allow that 1% of leeway for equipment accuracy, otherwise this unit wouldn’t get the pass. But it does get the pass, so we’ll move on.
Noise? Couldn’t hear any. Can’t measure it. The load testers are too loud to see how BeQuiet this unit really is, and there’s no way that’s going to change anytime soon, if ever. There’s just no way to do it easily using SunMoon load testing equipment, and at any rate, I’ve been doing this reviewing stuff since 2007 and am now getting comfortably into my forties… I’m thinking I’m much closer to the end of the ball game than the beginning by now.
Let’s computerate the load regulation now and see how stable the unit is. Going from left to right above, I see 3.3%, 1.8%, 0.9%, 0.7%, 0.8%, and 0.8%. That’s an average of 1.38%, or on the low side of excellent. I think if the minor rails were improved just a smidge, this unit would track a little better with the best on the market, but as is this is by no means a bad result. As I said, it’s still my definition of excellent. Just barely.
