The hourglass of time finds us now on page four, gazing in awe and wonder at three near perfect power on spike test results. It looks like the S&C point is safe from deduction later, as this is exactly what I like to see in these tests.

All we need to do yet is run the hot tests and confirm the unit still does the performance we saw when cold.

And once again, the fan only stayed off for test one. This unit simply runs too warm to keep it off for long.

Good news from the voltage table, though... all three rails have improved their regulation from the cold tests. Now, we see 3.79%, 2.40%, and 1.50% in the above table going from left to right. That means our average has come up to 2.56%. Almost enough to move into a better scoring bracket. Almost. It's still on the wrong side of the line, though, and I still need to call it strictly average.

Let's examine the scope shots and see how ripple control turned out.

Hmm... yeah, that's about what the box led me to believe things would look like. 40mV or so for the 12V, under 25mV for the other two. I'll have to score a minor deduction against the 12V but the others are safe.

That's it for the testing. Time for my pecs and I to take this unit apart.
