Asus A8V-VM SE - Manual (Page 32)

1-20 Chapter 1: Product introduction
2. USB device wake-up (3-pin PS2_USB_PWR)
Set this jumper 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 USB device wake-up feature requires a power supply that can
provide 500mA 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.
