Asus P5GZ-MX - Manual (Page 37)

ASUS P5GZ-MX 1-25
• The USB device wake-up feature requires a power supply that can
provide 500 mA on the +5VSB lead for each USB port; otherwise,
the system would not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
3. USB device wake-up (3-pin USBPW1-4, USBPW5-8)
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 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).
The USBPW1-4 jumper is for the rear USB ports (USB port 1-4). The
USBPW5-8 jumper is for the internal USB connectors (USB port 5-8)
that you can connect to additional USB ports.
