Moving on, a peek at the power on spike tests before we get to the good stuff. These scope shots are as close to perfection as you can get in this game. No out of control spikes to be seen, perfect rise time figures… you just can’t ask for any better.

Now… the hot tests. As this unit is rated to forty, I’ll turn on all the hot box fans and crack the window a little bit. I don’t think the box will stop at forty, so I hope the unit is able to deal with that.

And… it was. We got all the way to forty-six without any shutdowns or any indications of issues. Nice!

Efficiency wise, the unit was down a bit from the cold tests. Even so, tests one, two, and five still meet Titanium. That’s just… I don’t have a word, so I’ll borrow one… shpadoinkle!

Over on the voltage readings, there’s been some change but not much. The 3.3V rail is unchanged at 0.6%, the 5V rail is now even more stable at 0%, and the 12V has slipped to 0.4%. That gives us an amazing average of just 0.33%. Yes, I’m sure I’d still see a deflection on the 5V rail if the meter had the resolution to show it, but my bank account never has the cheddar for more expensive test gear so this will have to do.

I wonder if the scope shots can make us any more impressed than we already are.

And the answer to that question is abso-friggin-lutely, they can. The 12V rail? We’ve got about 17-18mV there. That’s all. The other two rails are so well suppressed I can’t really tell how low they are with my current scope settings. They’re certainly no higher than 8mV.

Is it legal to marry more than one power supply in Saskatchewan?
