The NZXT HALE82 N 650w, the unholy mother of minor rail ripple under warm temperatures.

Look at that.

The NZXT HALE82 N 650 W provided ripple and noise levels outside the specifications, which can cause problems on your computer. See the results in the table below. We marked in red the values that were outside the allowed range. Investigating this problem further, we discovered that when the power supply was “cold,” values were inside the proper range. But as the power supply heated up, noise and ripple levels started increasing very fast. This problem started occurring when the ambient temperature surpassed 35° C. Since we test power supplies between 45° C and 50° C, we have to consider this unit as having failed our tests. We requested a second sample from NZXT, and the results were absolutely the same, meaning that this problem is definitely a design flaw. NZXT told us that they only guarantee the correct functioning of this power supply up to 35° C, which matches our findings.

The ripple on the 3.3v rail hit over four times the limit on just the third test. The 3.3v ripple went TEN TIMES OUT OF SPEC UNDER FULL LOAD. So this thing really can't handle heat. The 5v rail's ripple also went out of spec by the fourth test.

So yeah, this is the unholy mother of minor rail ripple.

You see, NZXT actually had a little bit of money put into these things. That elementary schooler's weekend science project has no effort or money put into it, save for a dollar.
