Intel Desktop Board D845GEBV2/D845GERG2 Technical Product Specification

80

NOTE

IBM PS/2 Port Specification (Sept 1991) states:
275 mA for keyboard
70 mA for the mouse (nonwake-enable 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

NOTE

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.
