INTEGRATOR’S NOTES

Use only ATX12V-, SFX12V-, or TFX12V-compliant power supplies with the Desktop Board

D865PCD. ATX12V, SFX12V, and TFX12V power supplies have an additional power lead
that provides required supplemental power for the processor. Always connect the 20-pin and
4-pin leads of ATX12V, SFX12V, and TFX12V power supplies to the corresponding connectors
on the desktop board, otherwise the board will not boot.

Do not use a standard ATX power supply. The board will not boot with a standard ATX power

supply.
