• “Xbox One power supply” can mean three different PSUs, depending on the console variant:
– Original Xbox One (2013): large external “power-brick” (203 – 220 W).
– Xbox One S (2016): internal, ~120 W, universal mains.
– Xbox One X (2017): internal, ~245 W, universal mains.
• The bricks/boards are not interchangeable; always match the PSU to the exact model.
• All units accept 100-240 V ac / 50-60 Hz and supply regulated 12 V dc (plus 5 V sb for standby).
Architecture and electrical specifications
a. Original Xbox One (model 1540) – external PSU
• Input: 100-240 V ac, 2.1–2.5 A, 50/60 Hz (auto-range)
• Output rails:
– 12 V dc @ 16.5-17.9 A (main)
– 5 V sb @ 1 A (stand-by)
• Typical continuous power: 200 W (earliest lots 220 W, later 203 W)
• Active cooling fan, PFC, proprietary 2-pin DC plug.
• LED status on brick: white = on, orange = stand-by, off/blinking = fault.
b. Xbox One S (model 1681) – internal PSU
• Input: 100-240 V ac, 1.8 A, 50/60 Hz (auto-range)
• Multiple DC rails generated on-board (12 V, 5 V, 3.3 V, 1.8 V etc.)
• Rated ≈ 120 W (peak 135 W). Passive convection plus system blower.
• Standard IEC C7 “figure-8” cable. No external LED diagnostics.
c. Xbox One X (model 1787) – internal PSU
• Input: 100-240 V ac, 3.2 A, 50/60 Hz (auto-range)
• Output: up to 245 W to motherboard; highly efficient LLC resonant topology.
• Uses the same C7 mains cord as One S but higher output capability.
Common failure modes
• Original brick: fan seizure → thermal shutdown; primary MOSFET/rectifier failures after surges; bulged electrolytics.
• Internal PSUs (S/X): over-temperature from dust, mains surge damage to PFC or APFC controller, worn-out primary caps.
• Symptoms: no LED / no boot, momentary power-up then off, audible chirp (crowbar or OVP action).
Functional diagnostics
• Hard-reset (brick): disconnect AC & console for ≥ 10 s, reconnect.
• Measure outputs: expect 5 V sb present whenever AC is applied; 12 V only when console requests PWR_ON.
• For S/X, plug removal and 10-15 s front-button press discharges internal PSU; if still dead, in-console PSU likely faulty.
Electrical theory highlights
• 5 V sb is produced by a tiny fly-back converter that runs continuously; main 12 V is enabled by PSU-ON from the APU southbridge.
• External brick uses active PFC + resonant half-bridge; internal boards add synchronous rectification for higher efficiency (~92 %).
• Microsoft’s newer Xbox Series S/X continue the “internal, universal” PSU approach.
• After-market GaN-based replacement bricks (smaller, cooler) started appearing in 2023, but long-term reliability data are still sparse.
• Surge-protected smart outlets with energy monitoring are becoming a popular preventative measure.
Example: Checking an original brick with a multimeter
Analogy: Think of the 5 V sb rail as the “heart-beat” keeping the console’s brain dreaming; the 12 V rail is the “muscle” only flexed when you wake it.
• Safety: Opening any PSU exposes > 325 V dc on the primary bulk capacitor; only qualified personnel should attempt repairs.
• Compliance: Use UL/CE/FCC-listed replacements; cheap unlisted bricks can violate EMC limits and pose fire hazards.
• Warranty: opening S/X consoles voids remaining Microsoft warranty; EU regions still grant two-year consumer rights by law.
• Always verify wall power first; many “dead” units are tripped GFCI or faulty strips.
• Provide airflow: keep bricks off carpet; leave ≥ 5 cm clearance on all console vents.
• Preferred replacement order: 1) Genuine Microsoft, 2) well-reviewed UL-listed third-party (e.g., Ponkor, Sumlink), 3) DIY repair (experts only).
• If transporting a console internationally, only the mains cord plug needs adapting – the PSU is already universal.
• Internal PSUs for One S and One X are mechanically different; installing the wrong board may physically fit but will not align with standoffs or thermals.
• Reported coil-whine on some third-party bricks is nuisance, not hazardous.
• GaN replacements lack extensive field data; treat MTBF claims cautiously.
• Investigate GaN FET adoption in high-density console PSUs.
• Study long-term electrolytic capacitor aging in always-on 5 V sb converters.
• Explore firmware-based power telemetry on Xbox to predict PSU health.
The original Xbox One uses an external 200 W brick delivering 12 V @ ~17 A and 5 V sb @ 1 A, while the later Xbox One S (~120 W) and Xbox One X (~245 W) integrate universal-input PSUs inside the chassis. LEDs on the brick (white/orange) aid diagnostics; S/X rely on full console power cycling. Always match the PSU to the model, use certified replacements, ensure ventilation, and reset/test before replacing.
