I’ve now managed to blow up two of these. Starting to see maybe why that power supply isn’t so great. First was totally my stupidity. The second was because I unplugged it and plugged it back in while it was switched on. Both times it was the -12V one. Guessing it doesn’t really like being hooked up that way.
