IDE1
IDE Connector
This mainboard is equipped with 2 IDE connectors
to support up to 4 ATA-100/133 IDE drives.
It supports PIO and DMA mode operations for
maximum data transfer rate of 133MB/sec per channel.
When using two IDE drives on the same
connector, one must be set to Master mode and
the other to Slave mode. Refer to your disk
drive user's manual for details.
PW1: 24-pin ATX Power Connector
PW12: 4-pin ATX12V Power Connector
The mainboard is equipped with a standard 24-pin
ATX main power connector and a 4-pin +12V
power connector for connecting an ATX12V
power supply. The plugs of the power cables are
designed to fit in only one orientation. Insert the
plugs into the connectors until they fit in place.
Caution:
The PW1 and PW12 Power Connector must be used simultaneously.
The board requires a minimum of 400 Watt power
supply to operate. Your system configuration (amount
of memory, add-in cards, peripherals, etc.) may exceed
this minimum power requirement. To ensure adequate
power, for SLi mode use a 550 Watt or greater power
supply.
