Fan Connector Current Capability - Intel D845PEBT2 Specification

✏
NOTES
•
IBM PS/2 Port Specification (Sept 1991) states:
 275 mA for keyboard
 70 mA for the mouse (nonwake-enabled device)
PCI/AGP requirements are calculated by totaling the following:
 One wake-enabled device @ 375 mA, plus
 Five nonwake-enabled devices @ 20 mA each, plus
USB requirements are calculated as:
 One wake-enabled device @ 500 mA
 USB hub @ 100 mA
 Three USB nonwake-enabled devices connected @ 2.5 mA each
•
Both USB ports are capable of providing up to 500 mA during normal G0/S0 operation. Only
one USB port will support up to 500 mA of stand-by-current (wake-enabled device) during
G1/S3 suspended operation. The other port may provide up to 7.5 mA (three nonwake-enabled
devices) during G1/S3 suspended operation.

2.11.4 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.
Table 57 lists the current capability of the fan connectors on the Desktop Board D845PEBT2.
