I have a workstation that's becoming a little long in the tooth, as it were. It's a rock solid system, but about a year ago it had a faulty power supply that I replaced. During the past 11 or so months, it's run just fine, but recently it again had a "hiccup" where it just died (no panic) and then rebooted. I suspect the power supply again, but I just don't know.
(Unfortunately the power supplies are not cheap for this server.)
It got me to thinking: Is there a way to test power supply input and output to find out if and when a power supply fails or is failing?
It seems as though there should be a way to measure both of these in/out lines (realizing that DC out on the inside is a little more involved) to monitor such issues…
