I'm trying to fix an relatively old but beautiful 2011 Aspire Z5801 All-in-one...but the power supply has crapped out. I can't for the life of me figure out an alternative psu to purchase. It came with a LiteON PS-3251-3AB. It only has a P1 10 pin and a P2 6 pin with a ground for cables. They come out of the side of it. It measures 20 cm long by 8 cm wide and 4 cm deep. I can't find anything comparable to fit inside an all-in-one. How does one go about finding an alternative or is my computer toast just because I can't find a correct power supply?
