Ok so it has been a while since i posted here ( a really long while) and now i can't find anything. but here goes the question. I think my power supply is burned out but i am not sure because the LED on the mother board still lights as well as the power buttons backlight. But when you push the button nothing happens. Any ideas?
Has the power switch connector fallen off or are there any breaks in the wire? Sounds obvious, but I always overlook those things when I deal with a problem You can start an ATX PSU by shorting pin 14 (usually the green wire) on the main ATX power connector to any ground on it. This forces it to turn on and might be useful to you if you want to test it.
thanks that was my first thought and i am having trouble tracing the power switch wire because it is a dell. thanks fro the info on pin 14.
Find the power sw header on the mobo, should be on the bottom corner, opposite side to the PCI slots etc. Short the 2 pins with a screwdriver or something else metal, might be that the power swtich is dodgy. Also try as hitman suggested, but make sure you have some load on the supply, an (old) HDD or high power fan. Optical drive would work too.
