standard parallel ATA with 133 MB/s (Ultra DMA133).
If you install Serial ATA hard disk drives, you can create a RAID 0,
RAID 1, RAID 0+1, RAID 5, and JBOD conguration through the onboard controller.

•
We recommend that you use an ATX 12 V Specication 2.0-compliant power supply
unit (PSU) with a minimum of 300 W power rating. This PSU type has 24-pin and 4-pin
power plugs.
•
If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15 A on +12 V and that the PSU has a minimum power
rating of 300 W. The system may become unstable or may not boot up if the power is
inadequate.
•
Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will not
boot up.
• We recommend that you use a PSU with higher power output when conguring a
system with more power-consuming devices. The system may become unstable or may
not boot up if the power is inadequate.
• If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
•
You must install a PSU with a higher power rating if you intend to install additional
devices.

9. CPU fan connector (4-pin CPU_FAN)
The fan connector supports cooling fans of 350 mA~2000 mA (24 W max.) or a total
of 1 A~7 A (84 W max.) at +12V. Connect the fan cable to the fan connector on the
motherboard, making sure that the black wire of each cable matches the ground pin of
the connector.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
Ensure that the audio device of Sound playback is Realtek High Denition Audio (the
name may be different based on the OS). Go to Start > Control Panel > Sounds and
Audio Devices > Sound Playback to congure the setting.
