Atx Power Connector - AOpen AK33 Easy Installation Manual

JP12 Enable/Disable Onboard Audio
This motherboard has AC97 sound onboard. JP12 is used to enable or disable
onboard AD1885 CODEC chip. If you don't want to enable the Onboard Audio, you
should set this jumper to 2-3, and disable the "Onchip Sound" from BIOS setting >
Advanced Chipset Features, before you install your preferred PCI Sound Card.

ATX Power Connector

The ATX power supply uses 20-pin connector shown below. Make sure you plug in the
right direction.
Warning: For ATX system, there is always a standby current on the
motherboard. Please make sure that you have unplugged the ATX power
cable from the connector before you insert or pull out any CPU, DIMM,
PCI and AGP cards. Otherwise, a serious component damage may occur.

of CPU orientation. Plug in the fan cable to the 3-pin
CPUFAN or FAN connector.
Full-range Auto-Detect CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be
automatically detected and the range is from 1.1V to 1.85V.
Supported CPU Frequency
Core Frequency = CPU Bus Clock * CPU Ratio
EV6 Bus Speed = CPU Bus Clock x 2
PCI Clock = CPU Bus Clock / Clock Ratio
AGP Clock = PCI Clock x 2
