I was replacing a 400v 120uf capacitor in a power supply (ac 120v-19v DC 4.62 amps) well I was a dumb ass and stuck in backwards somehow.
I tested the dc out end while it was still plugged in and got 0.07 volts.
As far as I can tell although being plugged in for 2 minutes (approx) it did not get boiling hot (was barely warm when I reopened it).
Upon visual inspection there does not appear to be any bulging or cracks.
I don't just want to turn it around have it explode, is there a way to check and see its still safe? Is it even likely to be? From what I've read people have mixed opinions but the general consensus is how long vs how many volts, is there a way to be certain?
Realistically I don't care if I just toss it I'm more interested in future so I can recycle parts and components safely.
