The original Xbox One takes an external power supply brick. The Xbox One S and Xbox One X use an internal power supply and need no brick.
Match the brick to the exact console generation. The original Xbox One’s power supply unit (PSU) is no longer manufactured, so the market is crowded with third-party units of varying quality.
Which Xbox One Models Need An External Power Supply?
Only the original Xbox One uses an external power brick. The S and X move the power supply inside the chassis.
- Original Xbox One — external PSU plus AC power cord.
- Xbox One S — internal power supply; no external brick.
- Xbox One X — internal power supply; no external brick.
A brick advertised for the S or X is either an internal component you should not buy loose, or it is mislabeled. Microsoft’s power supply guidance for the original Xbox One covers the external brick only.
Replacement-component guidance for Xbox Series X|S is a separate Microsoft support program and is not a way to identify an Xbox One PSU.
How Do You Verify A Replacement Brick Before Buying?
Verify the model first, the electrical specs second, and the seller’s documentation third. A unit that fits the socket but mismatches the console is the failure case Microsoft warns about.
- Read the model identification on the console and confirm it is the original Xbox One.
- Buy a PSU explicitly labeled for the original Xbox One — not an S/X internal supply, not a generic adapter.
- Check the electrical specifications, connector, AC input, and regional plug against the console and listing.
- Prefer a genuine Microsoft part, or a replacement whose compatibility is documented for that exact model.
- Reject anything advertised only as “Xbox compatible” without naming the supported console.
Never modify connectors or pair an unrelated brick with a spare cord. Microsoft states it does not license non-Microsoft accessories that plug into the Xbox One power socket, and an incompatible unit may damage the console and void its warranty. This roundup of tested Xbox One power supplies narrows the field before you commit.
| Console Model | Power Supply Type | What To Buy |
|---|---|---|
| Original Xbox One | External PSU brick | Model-specific external unit plus AC cord |
| Xbox One S | Internal | Nothing — no external brick used |
| Xbox One X | Internal | Nothing — no external brick used |
| Xbox Series X|S | Separate support program | Not an Xbox One PSU |
What Should You Check Before Assuming The Brick Is Dead?
Reset the original Xbox One PSU before buying a replacement. Microsoft’s procedure rules out the most common false alarm.
- Unplug the power cables from the console, the wall outlet, and the PSU.
- Wait 10 seconds.
- Reconnect power to the wall outlet and the PSU — leave the PSU disconnected from the console.
- Check the LED on the PSU and follow the diagnostic steps for the light state you see.
- If the console still will not power on, test it with a known-compatible PSU or arrange service where available.
Ventilation matters as much as voltage. Keep the brick in open air and never cover it or tuck it behind the console. Retire any unit with a damaged cable or connector, cracked housing, liquid exposure, or signs of overheating, odor, arcing, or noise. Unplug power before inspecting or reconnecting anything, and do not open a mains-powered PSU unless qualified — replacing it is the safer call.
Which Buying Mistakes Cost The Most?
- Buying an external brick for an Xbox One S or X, which have internal supplies.
- Buying an S/X internal supply for an original Xbox One.
- Choosing by connector fit without confirming electrical and model compatibility.
- Mixing up Xbox One parts with Xbox Series X|S components.
- Assuming a third-party listing carries Microsoft approval — it does not.
- Reusing a damaged AC cord because it still plugs in.
The original Xbox One and its PSU are no longer manufactured, and Microsoft’s support pages list no retail price, part SKU, wattage table, or availability. Any specific figure must come from the retailer listing you are buying from, checked that day.
Common Questions
Can I Use An Xbox One S Power Brick On The Original Console?
No. The S has an internal power supply, so there is no external brick to move over, and the internal component is not a substitute for the original console’s external PSU.
Does The Original Xbox One Power Supply Work In Other Countries?
The external brick ships with a regional AC cord, so you match the plug to your outlet. Microsoft notes the internal supplies in the S and X work in all regions, but that does not extend to the original console’s external unit.
How Long Should I Wait Before Testing A Replacement PSU?
Run the official reset first: unplug everything, wait 10 seconds, then reconnect power to the wall and the brick while leaving the console disconnected. Watch the PSU LED before plugging the console back in — the light state tells you whether the fault is the brick or the console.
