3. USB device wake-up (3-pin USBPWR12, USBPWR34, USBPWR56,
USBPWR78)
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). All jumpers are set to pins 1-2 (+5V) by default because not all computers have the
appropriate power supply to support this feature.
The USBPWR12 and USBPWR34 jumpers are for the rear USB ports. The USBPWR56 and
USBPWR78 jumpers are for the internal USB header that you can connect to the front USB ports.
K8V-MX USB Device Wake Up
● The USB device wake-up feature requires a power supply that can provide 500mA
i
on the +5VSB lead for each USB port; otherwise, the system will not power up.
● The total current consumed must NOT exceed the power supply capability (+5VSB)
whether under normal condition or in sleep mode.
4. Force BIOS recovery (3-pin BIOS_R)
This jumper allows you to force recover the BIOS settings when the BIOS gets corrupted or
destroyed.
