In this instructable I will show you how to turn an X-Box 360 PSU into a high ampere 12v power supply. This is simple and it only requires a few parts. In the 2nd hand store, I found and X-Box 360 PSU for $10 and I looked at the back and thought this great for a 12v Supply because it could output a lot of amps, 12.2 to be exact.

So I tracked down the wire Identification and I made one into a 12v Power supply.

P.S(U) I was using an Iphone Because my camera was dead and I'm 13 so please no bad comments!

Lets Cut the X-Box connector!

Step 1: You'll Need...

Picture of You'll Need...

You will need a few basic things for this project...
1. An X-Box 360 PSU (power brick)
2. Heatshrink
3. A small length of Red and Black with able to withstand 12 to 16 amps.
4. Two 15A alligator clamps
5. Solder

The tools you will need...
1. Soldering iron or station
2. Wire cutters
3. Wire strippers
4. Something to shrink heatshrink (My mini blowtorch)
5. Crimp tool

Step 2: First Step

Picture of First Step

Strip the main insulation taking care not to cut the cores' insulation. After that, You will come across 8 wires. 3 black, 3 yellow, a blue and a red.
Strip the red and blue wires and twist them together. After that, Solder them together. Then move on to the next step.

Step 3: Second Step...

Picture of Second Step...

Strip all the yellow wires and twist them together. Tin the conductor after that with solder.
Now take on end of the thick red bit of the cable and put some heatshrink over it
After that, solder them together like in the picture and melt the heatshrink over the newly soldered joint
Next step...

Step 4: The Highly Anticipated Third Step

Now repeat the procedure with the ground and black wire. Heatshrink it.

Step 5: Almost Done... Well Sortof

Put the big bit of heatshrink over and shrink it. Make sure the red and blue wire are in there. I used a short piece because it was the only bit I had. You're almost done.

Step 6: The Aligator Clamps

Now it's time to put on the aligator clamps. Strip the other ends of the thick wire and tin both negative and positive. Then put the clamps on making sure the clamps are the right colour for the polarity. It will save a lot of confusion

Step 7: All Done!

Picture of All Done!

All finished. Plug it in and try it out.

Now you have got your own high power 12v supply!
Have fun and enjoy!

Thanks, saved me time.

could I wire 2 of these in series?

Noaha1 (author)2016-07-16

note: if you are making a 3d printer this is much easier to understand than some other instructions online

dang.artman (author)2014-11-07

Nice tutorial. The only thing I'm going to change on mine, is to hook the red and blue wires to a button or a switch so I can turn it off and on without having to unplug it.

tvarhol (author)dang.artman2016-05-17

Is the blue wire just like the remote wire on a deck?

SimonK48 (author)2016-04-10

I have the 8 wire version, just bought it in a junk sale. Okay so I can put a switch between red and black to turn it on and off. If I want a 5v rail I tap the red wire and use the black as the ground for it?

calebpike (author)2016-02-06

Great job! Question: I tried this but after a few seconds of the red and blue being connected the light turns red :-( Any tips for solving this?

glen.raymond1 (author)2015-12-20

i have come with 11 wires XD

Nice! I made it! :)

Pioneer car stereo wired to my power supply! Awesome!

JasonW12 (author)2015-08-24

On mine the plug popped open very easily meaning no cutting the end off. This meant no need to strip the outer cable and easy access to all the wires :)

I am looking for a diagram for Xbox power supply I am looking to up the 12volt up to 13.8 Amy ideas I have 25 power supply's to modify for use with ham radio I build a load tester when you put 10 to 11 amp load on xbox ps voltage drops to 11.6 need to adjust regulator up to 13.8 thanks

Needs more Flux (author)kb5ssq2015-08-14

If you open up the case (4 screws under the pads to open the case, then 1 internal screw on a heatspreader to separate the psu from the heat spreader) there is a trimpot that is most likely a voltage adjust.

kb5ssq (author)Needs more Flux2015-08-15

thanks i bought 25 of these power supplies wanting to use them for radio and there are so many different boards every one i take apart is different than the last i have not seane a trimmer but i have not removed any heat sinks ill try that and have a look thanks

Thanks, I am building a low power HTPC/DVR and I have a spare X-Box 360 power supply sitting around. I am getting one of those 12V 160W pico ATX power supplies and am using an AM1 motherboard (VGA, DVI, and HDMI outputs) and Athlon 5150 APU (25w) with 4gb DDR3 (one module) so the power draw should not be so bad, I will recheck the power for the 1 TB drive. I will put a plate with a fan on the back where the uATX power supply currently is. I am trying to make this work with MythBuntu OS and a Silicon Dust dual network tuner. I will add a small toggle switch on the back of the case to power down the brick for those times I may need to leave the HTPC off for a period of time. Does anybody else have any recommendations or would MythBuntu be the best way to go?

One disadvantage of this power supply is that it does not switch into current mode when temporarily overdriven and short recovery requires pulling the cord. I have 203W 12V 16.5A XBOX 360 power supply and several 1.5ohm heating loops, should be able to power two loops, but only one works. When powering two, the supply LED goes red and no voltage until power supply mains cord is disconnected.

Are they in series or parallel?

jonathan.stucken (author)2014-12-10

Great instructable... thank you!

monkeyracing (author)2014-11-22

This is an awesome Instructable. I did something similar with an 18v power supply from a satellite TV receiver, but it only puts out 6.5a. I had no idea the X-Box PSU was good for 12a. I've got something new to hunt for!

ShippingGuy (author)2014-06-14

Cool, nicely done.

thekanester (author)2014-06-05

Hey, thanks for the instructable. The cruddy PSU on my Printrbot has just gone on the fritz and I had a spare one of these lying around. Took me no time at all to knock up a replacement with your guide.

lairdkelly (author)2014-05-04

Saves me from hunting down a "big iron" PSU for an old Yaesu Land Mobile transceiver - the radio even has a pair of dedicated contacts to switch the PSU on and off!

DustySeven7 (author)2013-10-13

just a idea, put a switch between the red and blue wires and you should be able to turn it off and on

dog digger (author)DustySeven72013-12-07

I actually did that in another one I modded

nobody394 (author)2013-08-29

I gotta old 175W brick and I put a switch on the red and blue wire. When its on i get 12v 14.2A and when its off the 12v lines drop to 5v at 1A, pretty cool... if you wanted both 12V and 5V at the same time, make another lead off the red wire, FYI. 5V is always on too. Thank you for the Instructable, simple, effective and puts an out of date PSU to use

invadurxzim (author)2013-05-11

ive done this with a 175w psu so far so question how reliable is this?
i would like to use this to power a car amp to a guitar 4x12 interested in doing this as i dont really need a traditional guitar amp head as i use it only to make my signal loud :) and ive toyed with using pc psu but no to good result burn out my better amp fried an ic on the bridge switch i think someone bumped it on while i had it sitting idle :( .anyways .i have had one 360 psu burn out but that was with a 360 using it

cdances (author)2013-04-24

I did this for a 203 W Xbox PSU. There were 10 wires instead of 8, and some extra insulation. However it still worked great! Thanks.

le-Sid (author)2013-04-14

Nice instructable. Actually, i've got one of these taking dust in my drawers... Now I know what to do with it :-)

dshillingford (author)2013-02-23

Thanks for this. :)

hightekrednek2396 (author)2011-04-19

What are the red and blu wires are they 5v?

The red wire is 5v and the blue is some sort of ground. It's for starting the PSU. Similar on a computer power supply

Skater_j10 (author)dog digger2011-07-23

So the blue wire is called the Power Enable line, it senses if there is voltage applied to it and turns the 12V rail on if it sees 3V inside the 360. My tests have found that you can hack the circuit be sending 1.5V to 5V to this line and it will still enable the power. That's why using the 5VSB line (called 5V voltage standby which is always on as soon as the PSU is plugged in) will work in activating (enabling) the PSU by hooking it up to the PWR Enable line.

By the way while I'm here, I was curious to where you got the inspiration for this hack?

dog digger (author)Skater_j102011-07-23

Thanks for the info!
I got the inspiration from looking at my power brick because I was bored and I found 12v at high amps in the specs. Then I looked on the internet for the plug pin out and worked it all out. I found an xbox 360 PSU for $6 and I bought it!

You give me hope that I don't need to yell, "Get of my lawn!" at every youngster. You're heading to good places!

ogeorgescu (author)2011-09-08

Great job! I'd suggest using different lengths wires for the alligator clips to reduce the chance of shorts. I'd probably go even further and perhaps use some kind of bullet connector with the female end instead of the alligator clips.

dog digger (author)ogeorgescu2011-09-10

on most of my PSU mods, I've put on insulated gator clips. Even if there is a short, there are all sorts of protection devices installed in the PSU's

xXNuggettXx (author)2011-08-03

My 360 PSU (203W) has 10 cables total. 4 Yellow, 4 Black, 1 Red, and 1 Blue. One of the Yellow and one of the Black are smaller than the others. Any ideas what the extra wires are for?

dog digger (author)xXNuggettXx2011-08-03

They are probably for a low amp output. Just don't use them.
