Hold-Up Time and Inrush Current
For what it's worth, we were unable to get usable readings from Antec's power supply during our Inrush Current test.
and i was making popcorn.
Pleasant read, though, I like PSU reviews.
Edit: Yup, that's the correct testing equipment/procedure!
Why is the 80 plus spec officially test by having more load on the 3.3v and 5v rails?
Clearly loading the 12v rail would give us a better overall image
Never mind I see the ripple data buried in the individual tests. It would have been better in the summary side-by-side tests.
