Bought from auction with the assumption it worked. However it did not power on, I have opened up the Xbox and determined: PSU is working fine (voltmeter test) and so is the southbridge, therefore there must be a short on the APU board. However this is past my skill level and I am therefore selling as spares and repairs. No returns, sold as seen and the tests above are no guarantee. All serial numbers have been noted to prevent any fraud. Other than not powering on, it seems to be in good condition. All ports seem good condition. Everything is included that you would find in a normal Xbox series X. Please note that some screws are missing. Any questions, please ask.
