When I load test, well you know I’m gonna be, I’m gonna be the man who runs a load tester for you. When I measure, well you know I’m gonna be, I’m gonna be the man to… aw, nuts to this. The Proclaimers have way more than the one good song I could be referencing right now. So while I’m worth my room on this earth, here’s the gear I’ll be using for load testing: one SM-268 load tester, one Rek RF9901 power meter, one Extech DMM, one dual probe thermometer, and the Tektronix TDS-2012B scope.
I’m on my way to test standby efficiency today. Uh-huh, uh-huh, uh-huh, uh-huh.

|Test #||+5VSB||DC Watts/
No surprises here. This unit shares the same standby circuitry as big brother, so it gets roughly the same results. Better than average for efficiency, but nothing too spectacular apart from test one pulling down that fantastic 82% number.
I get 1.4% for a load stability result, which is an excellent number to see here.
We’re off to the main tests, now.

* Fanless operation.
The 1kW unit was mind-blowing on these tests, clearing Platinum. This one… is not quite up to that challenge. But, we do get a pretty clean pass for Gold, and that’s really all we can expect. I’m happy, anyway.
Fanless mode operated up until test three, and then the fan kicked in as soon as I hit the button for test four. It’s basically the same result there we had with the 1kW.
Let’s run some numbers on the voltage readings. For stability, moving from left to right, I see 0.6%, 0.2%, and 0.9%. Sa-weet! That’s an average of only 0.57%, which is way better than excellent. Corsair, you are off to an amazing start again, here.
