Known issues:

• Proprietary power supply connector

Some or all versions of this motherboard use a non-standard power supply connector, limiting compatibility with power supplies. It is highly advised to NOT apply power to the board prior to checking the connector pinouts and ensuring they are compatible. Failure to do so can permanently damage both the motherboard and the power supply.

We invite you to join our Discord community for assistance in repairing the damage or locating a compatible power supply.

Notes:

OEM only model. Standard AD1819A, optional YMF724 onboard audio, mainly used in the Dell Dimension XPS T series. The power connector on the Dell variant is DIFFERENT from standard. Apparently if you move it to the other position it will be standard ATX. Please check and verify existing documentation on how to do so.
