wrench 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.

  • Expansion slots are on proprietary riser

The listed slots are on the riser card that came with the motherboard.
If you have this board make sure you have the riser for it.
