#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.
