20 Most Recent RaidMax (KY-520ATX) 420-Watt Power Supply Questions & Answers

You can actually test the power supply before connecting it to the motherboard. Take a look at the power supply pinout by CLICKING HERE. Jump pin 14 with 13, 15, 16, or 17 to turn it on. You will have to get a manual for your motherboard to see how the front panel connector is configured with your case power switch. If you have that manual you can jump the 2 connector pins for the power switch to test the p/s from the motherboard.

Test the PSU. Unplug it from the motherboard and then with nothing connected, short the green wire to any ground (usually a black) using a paperclip and it should come on and stay on if the problem was with the motherboard/computer but if it shuts down, then you know the problem is the PSU itself.

If the PSU stays on under no load, then one possibility is you had too much connected to it and it shut down as a protective feature. The Bios would not beep if the PSU is shutting itself down. Also make sure you have the internal speaker connected. It's possible you just can't hear the beep because there is no speaker connected or it may be connected to the wrong place.

Don't throw away a defective power supply. It is worth a couple bucks as parts for an electronics enthusiast. Keep it out of the landfill.
