Before we do the actual hot tests, three words about the above screenshots: nice, weird, weird. And now I know we're dealing with Channel Well as the OEM, because we saw the same squiggly line thing with the big Thermaltakes. They are all built on the same CWT platform.
No worries though, everything is in spec here.
Time to do some shaking and some baking. I'll be doing the shaking, because I've had a little too much caffeine, and the hot box will be doing the baking. I'll keep all the auxiliary fans off, because only the top SM-268 heats the hot box.

And there you have it. Fifty degrees, no problemo. The unit does get a mite hotter at the exhaust than I would like to see, but all the voltages look healthy and the efficiency is still a clean pass for Platinum so I won't worry about it.
Speaking of the voltages, let's run the numbers one more time. Now, I see 1.5% for the 3.3V rail... that's a pretty good improvement. The 5V rail is doing the same as it did cold, at 1.2%, but the 12V rail has also decided on an improvement at 1.1%. That gives us an average of 1.3%. The Deepcool unit did it, folks... we are now into the excellent regulation scoring area. Sweet!
Now... the line cord. At full growl, I measured 12.03 amperes of current at the wall with 116.5V input. 18 gauge is not enough at full power. 16 gauge is enough, barely, however this does not account for any brownouts at which time the 16 gauge becomes pushed a bit too far. To be safe, I strongly suggest that Deepcool package these with 14 gauge line cords.
Let's see what the scope shots tell us.

Well, they don't tell us this power supply is as amazing as that Antec I just reviewed, but they do say that this is a respectable unit indeed. The 3.3V rail is at 40mV... that's outside my requirements for no scoring deduction there. The 5V rail is another story, at an excellent 25mV. Meantime, the important 12V combined rails are sitting right around 50mV. Not an excellent result there, but certainly very good.
So, there will be scoring deductions on page six, but we'll get to that later. For now, we're taking this unit apart.
