You can purchase a power supply tester, they are not that expensive. Here is a link for some and if you want you can shop around. Make sure to get a 20/24 pin tester.

Also if you do have a bad power supply here is a replacement.

Take the power supply to a retailer or computer shop in your local area to be tested. Pretty standard from what I have found out.

The power supply is very inexpensive and can most likely be bought from any of your computer retailers, Amazon - Just make sure to confirm the right model type of power supply. BEST to have it tested before replacing it. To make sure that is the issue..

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

Go to this link. Click HERE. Unplug from the motherboard FIRST. (all other leads too) You can test by using a paper clip to short pin 14 (green) to 13,15,16, or 17. This will power on a working power supply.

I think my power supply is dead. Computer unresponsive, no cooling fan, etc. Is there a way to test the output with a voltmeter? Thank you.


You can use a paper clip and jump the connection from the green wire to a black wire next to it, this will force the power supply to turn on. If the PSU turns on, the means your issue probably lies elsewhere in the system, like a bad power switch or connection.

No pwr supply light on Pavillion desktop pc


Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic
