How to Choose the Right Power Supply Brick for Your Xbox One?

Only the original Xbox One uses an external power brick — the Xbox One S and Xbox One X have internal power supplies, so the right brick is one made specifically for the original model.

A replacement brick looks like a simple black box, but plug in the wrong one and you can damage the console. Microsoft sells no licensed aftermarket brick, which means every unit on the shelf is a judgment call. The one thing that settles it: confirm which Xbox One you own before you spend a dollar.

Which Xbox One Models Actually Need An External Brick?

Only the launch model — the original Xbox One — takes a separate power supply unit. The Xbox One S and the Xbox One X both run on internal supplies and have no brick to replace or buy.

Check the back of the console. If a thick cable runs from the console to a large external box, you have the original Xbox One. If the power cord plugs straight into the console, you have an S or an X, and an original-model brick will not help you.

Do not substitute a power component from an Xbox 360 or an Xbox Series X|S either. Microsoft’s Xbox One documentation does not list any of those as compatible with the original brick, and the connectors differ.

What Should You Match Before Buying A Replacement?

Match the brick’s electrical input and output markings to the original unit and to the console. A visually similar box is not proof of electrical compatibility, and Microsoft warns that non-Microsoft accessories plugged into the Xbox One power socket can damage the console and void its warranty.

Before you pay, verify all of these on the listing or the label itself:

• Model and connector — the listing must name the original Xbox One, not “Xbox compatible.”
• Voltage and current — the output figures should match what the original brick states.
• Certification markings — a legitimate unit carries recognized safety certification.
• Region — US buyers need a unit built for US voltage with the correct US mains cable.

A plug adapter does not convert voltage, so an imported brick can be unsuitable for a US outlet even if it physically fits. Microsoft states that the Xbox One S and Xbox One X internal supplies work in all regions worldwide; that guarantee does not extend to the original external brick.

Where To Find A Reliable Original Xbox One Brick

Genuine Microsoft units are the safest choice, but both the console and its power supply are discontinued and out of warranty, so Microsoft no longer sells or services them. Replacements now come from remaining inventory and third-party resale.

Buy from a seller with clear electrical specifications, stated warranty terms, and a return window. If you want to compare tested options side by side, this roundup of the best Xbox One power supply bricks does the narrowing for you.

Microsoft publishes no official replacement price, no current retail SKU, and no approved third-party model list, so treat any listing’s claims with the same skepticism you’d apply to any discontinued-part purchase. Inspect the brick, cable, connector, and insulation the moment it arrives, and stop using any unit that smells hot, sparks, makes abnormal noise, overheats, or repeatedly shuts down.

Wherever the brick ends up sitting, give it ventilation. Microsoft says the original power supply should not be covered or enclosed.

How Do You Reset The Power Supply When The Console Won’t Turn On?

The 10-second reset is the correct first move when the original Xbox One gets no power at all. Microsoft’s procedure drains the supply so it can restart cleanly.

1. Unplug the cables from the console, the wall outlet, and the power supply.
2. Wait 10 seconds — the pause is required for the supply to reset.
3. Reconnect the power cable to the wall outlet and to the power supply, but leave the console unplugged.
4. Check the LED on the power supply and follow Microsoft’s LED-specific troubleshooting steps. Microsoft’s Xbox One power supply reset guide lists what each light pattern means.

If the supply’s LED behaves correctly but the console stays dark, test it with a known-good outlet and cable. Continued failure points to the brick, the console, or both needing service.
