3. HARDWARE SETUP 18) Chassis Intrusion Lead (4-1 pin CHASSIS) This lead is for a chassis designed for chassis intrusion detection. After-market toggle switches may also be installed to the chassis panel or on any removable components. Two wires should be available from the chassis to connect to this lead. When any chassis component is removed, the contact should open and the motherboard will record a chassis intrusion event. The event can then be processed by software, such as LDCM. If the chassis intrusion lead is not used, a jumper cap must be placed over the pins to prevent unnecessary power loss. 01 01 01 01 01 01 3.

The plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned. IMPORTANT: Make sure that your ATX power supply (minimum recommended wattage: 200 watts; 235W for a fully-configured system) can supply at least 20 amperes on the +5-volt lead and 10mA on the +5-volt standby lead (+5VSB). Your system may become unstable/unreliable and may experience difficulty in powering up if your power supply is inadequate. For Wake-On-LAN support, your ATX power supply must supply at least 720mA +5VSB. ® K7M-RM ATX Power Connector K7M-RM +12.0Volts +5V Standby Power Good Ground +5.0 Volts Ground +5.0 Volts Ground +3.3 Volts +3.3 Volts +5.0 Volts +5.0 Volts -5.0 Volts Ground Ground Ground Power Supply On Ground -12.0Volts +3.3Volts ATXPWR 42 ASUS K7M-RM User's Manual
