XBOX One S Power Supply Replacement


XBOX One S Power Supply Troubleshooting

Difficulty Level - Medium

If your XBOX One S switches off after a few seconds, or doesn't power up at all (no signs of life), then you probably have a faulty Power Supply Unit. It will involve you buying a new PSU and getting inside the machine to fit it.

The Original XBOX One console had a big fat external brick powering the thing.

They changed a lot of features with the XBOX One S, including putting the Power Supply Unit inside the console instead.

For those who had an original XBOX One, if the console packed up, it was relatively easy to test the power supply, albeit by having to get a friends power brick to test it on. Then you'd have to go to Ebay and buy a second hand one.

Now they've moved the Power Supply Unit (PSU) inside the console, we haven't got the luxury of testing with an external brick.

We've gotta get inside the damn thing to troubleshoot the problem, which is a pain in the backside.

But fear not, it isn't that difficult to get at the PSU, but you will need a replacement PSU to be able to test the console.

So, if your XBOX One S is completely dead, or just switches itself straight off within a second or 2, it's a good bet that your power supply unit is faulty. (You can see a picture of an XBOX One S PSU above in the "Tools Needed" section)

The only way to troubleshoot this issue for an amateur, is to get hold of a replacement PSU. 

Then you have to swap it out and test it. See the video below for comprehensive instructions on how to do this.

You will need a Security Torx T8, T10, and a flat head screwdriver to get the console open. A Complete Console Repair Screwdriver kit can be bought above, from Amazon.

1. Take a large flat head screwdriver, and locate the black bottom shell cover. You need to go around the edge of the console with the driver, putting the driver in between the white shell and the black cover, and robustly wedge between the two, until it unclips. It takes quite a bit of force to do this.

2. You will need to remove the Microsoft seal on the back edge, which will void your warranty with Microsoft. Once the seal has been removed, pay particular attention to removing the black cover here - you may need a small flat head screwdriver to wedge it off - TAKE CARE here.

3. Put the black cover aside.

4. Remove all 6 of the green screws, using a security Torx T10 screwdriver.

5. At the back edge of the console, pull the chassis out from the shell, by pulling the edges of the top shell away from the chassis. This will free up the chassis, and it will easily come away from the shell. Discard the white shell.

6. Keep the silver fan cover on (for a moment while you remove the screws from the back)

7. Turn the console over, and remove the small torx T10 screws around the PSU and Hard Drive (see video)

8. Now remove the silver fan cover.

9. Pull out the hard drive. It will still be attached to the motherboard by 2 cables.

10. Locate the 2 cables, and pull them out of the motherboard.

11. Put the hard drive aside for now.

12. You are now ready to pull the PSU out. Pull the PSU up from its seating, and fold it out, so that it sits outside your console, but is still attached by the cable.

13. Get a large flat head screwdriver, and locate the plug on the motherboard. You will see a little clip at the side of the connector.

14. Take the flat driver, and push in the little clip, to release the cable from its plug. You need to be pretty firm with it.

15. Pull the PSU out, and swap it for your new XBOX One S PSU unit.

Now you have replaced your PSU unit, you can put the console back together again.

It may be worth leaving the shell off the chassis for now, while you go and test the power supply.

To test, simply go and plug it in and see if it boots up. You will need to locate the on / off button mounted on the RF circuit board, if you test without the white shell on. Otherwise, put your console back together carefully, as shown here.

RF Board 

If your console still doesn't work after a replacement PSU, and the console is completely dead, there is a possibility that the RF Board is faulty.

XBOX One S RF Board

The RF board carries the on / off switch on it. If this switch isn't working, or if the board is faulty, the console will not switch on.

Unfortunately, again, the only way to troubleshoot this is to replace the RF Board. It's easy to replace, once you have your console stripped down as stated above, the RF board has 3 screws on it. Once unscrewed, you can pull the RF Board off, taking care with the connector.
