4. USB Device Wake-up (3-pin USBV1, USBV2, USBV3)
Set these jumpers to +5V to wake up the computer from S1 sleep
mode using the connected USB devices. Set to +5VSB to wake up
from S3 sleep 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 USBV1 jumper is for the rear USB ports. The USBV2 and
USBV3 jumpers are for the internal USB headers.

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.
5. CPU voltage selector (3-pin VEN1)
This jumper permits an increase of CPU voltage of 0.2 volts.
It is recommended that you keep the default setting (Normal) for
system stability. Raising the CPU voltage may cause system failure.
