ASUS P8H61-M LX2 R2.0 1-22

• 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 350 W.

•

DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will

not boot up.

• We recommend that you use a PSU with higher power output 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.

2. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)

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.

3. Serial port connector (10-1 pin COM1)

This connector is for a serial (COM) port. Connect the serial port module cable to this

connector, then install the module to a slot opening at the back of the system chassis.

The COM module is purchased separately.
