Finishing Up

Now we need to connect the power switch to the receptacle, it should be just restoring the red wire between the two. Next, solder the power cable we mad to the receptacle. Take note which wires you had substituted. I used green to green, blue to blue and white to brown. After you finish soldering tape everything up nice and clean.

LAST STEP,. we hope ;-) Now after you get your machine all put back together you can test it. I plugged 1 cdrom into the new psu, just for testing. Plug the molex connector into your primary psu. Power up. VOIS LA! Hopefully after doing this your cdrom light comes on. Now power down, does the secondary psu power down also? If so congratulations. You have just successfully installed a second power supply in a mid or mini atx case. If the power supply stays on then you need to go back and look at the connections to the relay, something is probably crossed. If the relay is fine but you have no power, make sure your power switch you just installed is turned on. And last but not least, if sparks shoot out, catches your dog on fire who then runs  into the curtains which promptly burst into flames and burns down your house, please re-read the disclaimer provided above. ;-)

Every thing is working fine. All my cd roms and the lighter run on the secondary power supply. My mother board and my hard drives run on my primary, sweet.

 Now, what are we gonna use all this power for? hmm,..... ;-)
