Hello guys. I'm trying to debug this external drive PSU. It's a Mapower PD-80 and just outputs the standard 12V/5V over a couple of Molex connectors.

However, this particular unit is putting out 9V instead of 12V. Is this a capacitor problem?

(The gunk on the capacitors is not electrolyte but glue from a couple of labels that I pulled off. The capacitors have not burst.)

"This all reminds me when i took the windows vista sticker thingy off my old laptop, and on my washing machine as a joke. A few days later said washing machine stopped working. I still think this cannot be a coincidence."

Secondary capacitors appear to be Fuhjyyu "brand", which is one of the worst. Responsible, among others, for the deaths of countless Antec PSU's in the mid-00s. Replace them, and also check the fat one although it looks to be made by Hitachi so it should be still good.
