INTEGRATOR'S NOTES
•
Use only ATX12V-, SFX12V-, or TFX12V-compliant power supplies with this board. 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 desktop board will not boot.
•
Do not use a standard ATX power supply. The desktop board will not boot with a standard
