Powering Up A Standalone PSU Guide
Digg! Reddit!Add to Reddit | Bookmark this article:


There may be times when you might want to power up a power supply unit (PSU) without attaching it to any computer case. Perhaps you want to use it to test fans, cold cathode tubes or other modding stuff, without connecting it to a chassis.

Now, you might think it's easy - just plug in the PSU's power cable into the nearest power outlet and start the light show, right? Not quite. Let show you how.

First, look for your ATX PSU's 20-pin motherboard connector.

For the next step , you will need a paper clip or a short length of wire. A wire would be a better option, of course!

But first, please make sure your PSU is NOT plugged in for this mod! You WILL get a shock if you attempt the next few steps with the PSU plugged into a power outlet!

Just follow the green wire and insert one end of the paper clip or wire into its connector. Then look for one of the black (ground) wires. Insert the other end of the paper clip or wire into its connector.

Here's a picture from the front. Preferably, you should connect the green wire to the closest black wire.

After doing this, cover the 20-pin power connector with some tape. You should do this even if you are using a wire. This reduces the risk of anyone getting electrocuted by the mod! It also prevents the paper clip or wire from dropping out.

That's it! Just plug the power cable into a power outlet and turn it on. The PSU will immediately power up. From now on, you can turn the PSU on and off just by using the power outlet's switch.

As you can see, this is a very easy mod. It also works for a 24-pin connector. Just connect the green wire to any black (ground) wire.
