Power Supervisor; Fan Header Current Capability; Add-In Board Considerations - Intel DH77DF Specification

2.5.2

Power Supervisor

This board supports a version of the Power Supervisor feature which adds protection to
the 5 VSB power rail by limiting potential electrical overstress events to a non-
destructive level.
2.5.3

Fan Header Current Capability

CAUTION
The processor fan must be connected to the processor fan header, not to a chassis fan
header. Connecting the processor fan to a chassis fan header may result in onboard
component damage that will halt fan operation.
Table 39 lists the current capability of the fan headers.

Add-in Board Considerations

The board is designed to provide 2 A (average) of current for each add-in board from
the +5 V rail. The total +5 V current draw for add-in boards for a fully loaded board
(all three expansion slots filled) must not exceed the system's power supply +5 V
maximum current or 14 A in total.
Maximum Available Current
2.0 A
1.5 A
