I better start this guide with this! This will definitely void your warranty! I take no responsibility for what you are about to do! This involves tinkering with your PSU and if you got a shock from it, it's your fault! If you hosed your hardwares, it's your fault! If you hurt someone, it's your fault! If you....damn it! You got the point! You do this at your own risk! 'Nuff blabbering, let's get to it!

   Do you have a peltier in your PC? Or do you have tons of fans (like me) running in it? Are you worried that you might tax out your PSU by having all those stuff in there? Or do you just crave for more power? Until recently, the only way to have an extra PSU in your system was to install an AT one with the switch. That extra PSU is usually used for powering up the Peltier or the tons of fans you have in the PC. Something we overclockers and case mod freaks do to get more power. But a while back, I found a link to an article on how to connect two ATX PSUs together to get more power, but I somehow lost the URL. But then Speedy3D does an article about it and after reading through it, I just had to try it for myself.

   And when someone offered to buy my modded Enlight 7237 without the PSU, I knew that I could try my hands on the mod. The guide over at Speedy3D explains very well how to go about powering that ATX PSU without connecting it to your mobo. First of all, you will need to recognise the "Power On" line from the ATX connector of the PSU. It ain't hard to do coz there's only 1 Green wire there. That's the one!

Your ATX connector

A close up...see the "green" wire?

   All you need to do to power up the PSU was to "Ground" the wire. Meaning, connecting the "Green" wire to any of the 6 "Ground" wires from the same ATX connector and the PSU would power up like it was connected to a mobo! That was easy, wasn't it? OK, so that's the end of this guide! Hahaha! Joking! But, that means the extra PSU will be at the "ON" state no matter what state your PC is at, "ON" or "OFF". How about if you want to be able to switch it off?

You could do this....

   All you need here is a SPST switch, like the one below. Connect the "Green" wire to one post, and any of the 6 "Ground" wires to the other and you'll be able to switch the PSU "On" and "Off"! Simple wasn't it? You can mount that switch anywhere in your PC, but I prefer to mount it on the faceplate.

Or use this!

And do this!

   You can also mount an LED as an indicator to tell you if the PSU is switched on or not. But you can't connect it to the switch with the wires from the PSU already there, but you can hook it up to any of the female Molex connector of the PSU itself. Coz once the PSU is switched on, power will definitely be supplied to the Molex connectors too.

   Using any of the voltages available from the Molex, 12V or 5V, you can have the LED as an indicator. Just don't forget that resistor if you're using a low voltage LED like me. My LED is a 1.5V bright blue LED, so at 12V, you will need a 750 Ohms resistor and at 5V, you'll need a 240 Ohms resistor. Here, I used the 12V line. If you have a 5V LED, then you won't need the resistor.

An LED as indicator.

Wire up the LED like this.

   Now, there's no point in me blabbering on if I don't show you if the mod works or not, so here are more pics. Here you will see my 235Watts Enlight PSU all hooked up and ready to go. At this point, the main switch connected to the PSU is already on. The 80mm Sunon fan is also hooked to the PSU.

The Senfu DIY house comes in handy here! :)

All hooked up and ready to go!

   Here you see the switch turned on and up comes the LED and woosshh goes the fan! Awesome! Now all you need to do is find a place in your PC to mount this PSU! :) Well...this little mod worked for me. Now I can do my testing on the Baybuses without opening up my HX08 anymore! For those os you wants to increase the PSU wattage, you can hook up the PSU to another PSU for more fun! I don't have an extra PSU, so I can't do it.

   Furthermore, it involves cutting up the wires and joining it to the other PSU and it's kind of permanent. This is not. You can always remove the wires and have the PSU operating as a single unit. If you still wanna do it, I suggest you check out Speedy3D's Guide about it!

Voila! It's ALIVE!

   Well, that's all folks! Thanks for reading!
