Replace your original power supply with a standard ATX Computer power supply of your choice. Now you can have an inexpensive replacement, or, opt for more power, less noise, or both! The PSU Energyzer requires no assembly or wiring – just plug it in, turn on your PC power supply, and turn on your Xbox 360.

The PSU Energyzer is a special cable with an OEM Xbox 360 power plug on one end, and a 20 pin ATX connector on the other.
Please note that the original Xbox 360 Power Supply provides 203 watts, and 12v DC current at 16.5 amps, and 5v DC at 1 Amp. For the PSU energyzer to work, your PC power supply must provide this much SUSTAINED power at a minimum. Many PC power supplies are rated for PEAK power instead of sustained power, so you must check the label of your power supply to see if it provides enough sustained power.
