Hey folks! I need some advice on troubleshooting a computer power supply. I've read through the previous posts on Computer power supplies. Here is what I have so far:
400Watt ATX type PS. Model LPK2-30 (Datasheet available???)
1. The PS has been used on a continuous basis. (the PS and computer remained on for long periods of time (weeks at a time.).
2. When the power switch is pushed, the computer begins to boot, then suddenly turns off. This leads me to believe that the connection between pins 14 & 15 (PS On, and GND respectively)is possibly being opened, causign the PS to shut off?
3. Planning to short pins 14 & 15, and add a load to the supply (possibly fans or high wattage resistors) in order to measure the supply voltages.
4. Inspected the internal PCB for evidence of overheating / shorting. No signs are evident.
5. Inspected internal fuse, Good to go.
Does anyone have any other ideas for troubleshooting this issue?
