The Xenon motherboard is the first final motherboard and is used in the Original Xbox 360 series. The motherboard has a unique board layout compared to the later boards, especially noticeable with the capacitors around the CPU heatsink, and use of the ANA chip.
Notes
- At some point in 2006, at least one of the manufacturers of the Xenon started applying glue around the CPU and GPU, likely as an attempt to reduce the failure rate
- Some consoles use small yellow 820uF capacitors, while other consoles use silver 820uF solid capacitors
- Some capacitors used for voltage regulation positioned around the CPU heatsink are defective and prone to failure (see Capacitor Plague for details)
- At some point in 2006, the extended GPU heatsink started being used instead of the low profile GPU heatsink
