8. Digital audio connector (4-1 pin SPDIF_OUT)
This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port(s).
Connect the S/PDIF Out module cable to this connector, then install the module to a
slot opening at the back of the system chassis.
The S/PDIF module is purchased separately.
9. VGA Hotwire Connector
The VGA Hotwire connector allows you to precisely adjust the VGA card voltage directly
from motherboard BIOS, OC Key or TurboV EVO, reducing the risk of damaging
your VGA cards. Connect a 2-pin cable (purchased seperately) to the VGA Hotwire
Connector and weld the other end of the cable to the VGA card for voltage adjustment.
• Setting a high VGA voltage may lead to permanent damage to the VGA card.
• The motherboard does not provide a voltage increment higher than 3.3V.
