Asus P4B533-V manual USB device wake-up 3-pin USBPWR12, USBPWR34, USBPWR56

7.USB device wake-up (3-pin USBPWR_12, USBPWR_34, USBPWR_56)

Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V) by default because not all computers have the appropriate power supply to support this feature.

The USBPWR_12 and USBPWR_34 jumpers are for the rear USB ports. The USBPWR_56 jumper is for the internal USB header that you can connect to the front USB ports.

1. This feature requires a power supply that can provide at least 1A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up.

2.The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
