INTEGRATOR'S NOTES
•
Use only ATX12V- or SFX12V-compliant power supplies with the Desktop Board
D845GRG. ATX12V and SFX12V 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 and SFX12V 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 ATX power supply.
