2.11.2 Add-in Board Considerations
The Desktop Board D875PBZ is designed to provide 2 A (average) of +5 V current for each add-in
board. The total +5 V current draw for add-in boards for a fully loaded Desktop Board D875PBZ
(all five expansion slots and the AGP slot filled) must not exceed 12 A.

2.11.3 Fan Connector Current Capability
CAUTION
The processor fan must be connected to the processor fan connector, not to a chassis fan
connector. Connecting the processor fan to a chassis fan connector may result in onboard
component damage that will halt fan operation.
