Since someone requested the guide on how to power a 360 with a PC PSU, here it is.

Things you need:

Xbox 360
PC power supply
wires
dead 360 power brick(optional)
soldering gun(optional)

WARNING: I am not responsible for the damage caused due to the attempt to do this mod. DO NOT ATTEMPT IF YOU DON'T EVEN KNOW HOW BASIC ELECTRICITY WORKS.


First, the 360 power brick outputs 203w, 175w for the Foxconn Elite models. It does 16.5A on the 12v rail, aka 198w, 5w for 5v. The PSU I used is 144W on 12v, it works, I played Halo 3 on it for 4 hours without a problem, but I would still recommend a PSU that does more than 16.5A on 12v rail.

To start off, there's two way to accomplish this mod. One require 360, PSU, and wires only, the other one requires all the stuff listed above. The one that requires less materials is easier obviously, the other one is more difficult(soldering involved).

1. Get 360, PSU, wires, I got these from a dead PSU, 3 yellow(12v), 3 black(ground), 1 red(5v)


Standard ATX PSU


Xbox 360, and there's Pepsi's 360(duct tape one)




2. Here is the outline of the 360's power socket, 1-3 is ground(black), 4-6 is 12v(yellow), 7 is reference(not required), 8 is 5v(red)


Optional:Here is the backside of the 360 mobo's power socket, the numbers are the same. If you like soldering, or want it to be permanent, safer, some crap, you can do it this way.




3. Plug the wires into the 4-pin molex connectors of a PSU, match the colors so it would be easier to identify. Any connector on the PSU is fine.



Also, to make the PSU to be on standby, you need to get another wire/paper clip to make pin 14(green) and any one of the ground pin on the 20pin connector contact. i.e.




4. Get all the wires and make them flat with a clamp, wrench, etc. and fold the wiring back, example in picture. Make sure the the plastic part is flat so it can fit in the 360 power socket




5. Stick the wires inside the 360 power socket, 12v on middle row, ground at bottom, 5v on top left corner.

That's how it look like after sticking the wire in the socket.


Remember, the 5v is on the top corner, pay close attention the the picture below. As you can see, there's a tiny rectangular hole at the 5v area, #8, stick the red wire inside the rectangle.


Here's how it looks when it's done.


Optional: If you don't want to stick a wire inside the socket, you can get a dead 360 power brick's power connector, cut it away from the power brick, match the colors inside the connector, it's same color, yellow for 12v, black for ground, etc. Then twist the wires together and it should work the same.


6. Here it is when it's done.

Video if it in action


Reason why I didn't insulate the wire is because mine is not gonna be a permanent PSU for it since I still use the PSU for my other rig.

1st...why is that 360 covered in duck tape, 2nd. why would someone want to do this in the first place???

1st...because I like duct tape, 2nd. why wouldn't someone want to do this???

whats the point? you now have a big psu and wires hanging out the back of a 360...looks ghetto...and theres no point to it. the psu for 360 is perfectly fine.

We are modders, it could become pro looking...

Also those power bricks are one of the biggest downfalls in microsoft history.

Which is better? Spending $40+ on a 360 power brick if your old one is broken or do a mod with a $10 generic PSU?

If your power brick breaks or something, they're like 50 bucks!

And it could break again. (the $50 brick i mean)
I printed this out.

CSU_ComputerMajor

50 brand new yea...but it should have a warranty on it and you can find one used alot cheaper than 50...and no matter what you do to the psu it will still look like crap...IMHO....

Some people might do this mod for temporary. For example if your power brick broke, this mod can make your 360 work and when you buy a power brick, switch around.
