I have an AMD dual core cpu and it had an old Dnyex DX-PS500W PSU that started to give off a burning smell before it "popped" and had a blue flash and then died. I pulled the plug on it when it popped and flashed and then removed it. Cleaned out the PC of any dust etc. (There wasn't very much as the case has 3 fans). I grabbed an older 550 Watt 12V ATX PSU from an older pc and plugged it all in and the system is up an running again. But I'd like to keep this going so I wanted to get a new replacement PSU for the dual core pc. Without breaking the bank (as this is an older system) I was looking for recommendations from the experts here for a replacement ATX 12 V PSU. I'm not sure what other details you need but I'd appreciate any recommendations. I'm trying to keep the price under $50 if I can without compromising too much in quality. Can anyone give me any advice? TIA.
