Identifying Xbox Revision

This guide will step you through 100% identifying the Xbox revision you have.

While other guides may focus on identifying Xbox revisions by the serial number, manufacture date, DVD drive, or some other combo; these methods are not perfect.

Partial Disassembly​

iFixit has a great disassembly guide located here. It should only be necessary to follow up to around step 7.

Identifying Revision​

Following the reference image below you can quickly and easily identify your Xbox revision.

Power Connector​

  • If the power connector is a single row, like the one pictured, the system is a 1.0/1.1 revision.
  • If the power connector is a dual row then the encoder will need to be checked.

Encoder​

  • If the encoder is a Conexant or Focus then the system is a 1.2 - 1.5 revision (dual row power connector).
  • If the encoder is marked Xcalibur then the system is a 1.6 revision.
