2.Keyboard/mouse power and USB device wake-up (3-pin PS2_USBPW1-4)

This jumper allows you to enable or disable the keyboard/mouse and USB port 1-4 wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the computer by pressing a key on the keyboard, clicking the mouse or using a USB device. This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. The USBPW1-4 jumper is for the rear USB ports.
