Alright I had 2 PC power supplies I brought to work today to see if I could fix them. One had a blown Cap which was pretty simple. Just replaced it with the same cap and it works.
But the next one has me baffled a bit. When you trip the power on it will power up for a few seconds then power down and stop. I thought it might be the two big Caps, but I replaced those and still the same problem, but then again the replacement caps are used so they may not work. But before I get new Caps does this sound like a logical solution or do you think something else maybe wrong. It powers up for maybe 2 second and then dies. With the Volt meter on it goes right up to where it should be on the 12V and 5V rail but then just dies all together after the few seconds. It is a nice power supply and hate to scrap it.
Any ideas?
