Introduction: Convert Xbox Power Supply to Benchtop 12v Psu
I'm working on several 12v projects and need a power supply. I had an extra computer psu, and when digging around for parts found an old Xbox unit I thought would be cool.
I decided to use an old Dewalt drill bit case as the remote housing for the switch and power connections. Since the cable carries a switch leg the box can sit on the desk and the converter on the floor, helping with table space.
I dug around in my parts bins and found a switch and two cable terminals from a car audio install. The cable terminals will make connecting devices easy as they accept straight wire or banana posts.
Step 1: Prepare the Switch Box
I cut a hole for the switch (on the wrong side), hot glued scrap plastic over the hole, then cut a hole on the other side.... derp
I notched the case to fit the Xbox cable stop, which fit perfectly into a 1/2" notch. A little hot glue to help it stay in place.
I drilled 3/8" holes for the cable terminals, hot glued in place
Step 2: Wire Up the Box
there are 8 wires in the cable, 3 yellow (positive), 3 black (negative), 1 red, 1 blue (switch)
Twist the three yellow wires together and solder a single lead wire to the group of three. This will connect to the cable terminal. Repeat for the black wires.
Put terminals on the red and blue wires, connect each to one side of a switch.
Step 3: Connect a Peripheral
I used a few leftover banana terminals from a car audio install at the cable connection. They have a screw mount which makes it easy to swap wires. The cable terminals can accept up to 4ga wire as well.
I fired up my first test victim, a 50w Bluetooth audio amplifier. It will be my garage radio audio source and I want to connect and test before I wire and mount everything. Works perfectly for what I need.
We have a be nice policy.
