Chapter 2: Hardware information
Chapter 2
• For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Specication 2.0 (or later version) and provides a
minimum power of 600 W.
• Do not forget to connect the 8-pin ATX +12 V power plug; otherwise, the system will
not boot.
• Use of a PSU with a higher power output is recommended when conguring 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.
• The ATX 12 V Specication 2.0-compliant (1000W) PSU has been tested to support
the motherboard power requirements with the following conguration:
CPU: AMD Phenom 9950
Memory: 1024 MB DDR3 (x4)
Graphics card: PCI Express x16 Radeon 4870 X2 (x2)
Serial ATA device: SATA hard disk drive (x2)
Optical drive: DVD-RW (x1)
11. ATX power connectors (24-pin EATXPWR; 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are designed to t
these connectors in only one orientation. Find the proper orientation and push down rmly until the
connectors completely t.
