A decent load test of a PSU requires a decent load. Contrary to what some may believe, that means you need a known load that can fully stress the PSU. Computer hardware does not cut it. Worse if the PSU fails during testing it might take out the computer hardware anyway. Commercial load testers cost a lot of money. I do not have a lot of money, so I built my own with juicy power resistors and a Toyota cylinder head. It works great.
The ATX spec says that voltage regulation must be within 5% of the rail’s official designation, regardless of load. It doesn’t actually mention that the PSU shouldn’t explode, though I expect they figured it was implied. Exploding is a failure in my book regardless.
Not bad at all! In fact quite nice, really. Just to kick things up a notch I applied some heat to the unit in the form of 40c intake air and gave it a full load as well:
The PSU did not care. 12 V regulation through all tests was 00.49%, 5 V was 00.79% and 3.3 V was 00.59%. That's right folks, all rails have better than 1% regulation cold and hot, that is fantastic!
Last for regulation testing, a shot of the PSU wired for temps awaiting the Box of Heat.
