15) ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to an ATX power supply. The plug from the power sup-

ply 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 at least 10mA (750mA recommended) 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 750mA +5VSB.

16) System Message LED Lead (2-pin MLED)

This indicates whether a message has been received from a fax/modem. The

LED will remain lit when there is no signal and blink when there is data re-

ceived. This function requires an ACPI OS and driver support.

17) System Management Interrupt Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green”

mode, where system activity is decreased to save electricity and expand the life

of certain components when the system is not in use. This 2-pin connector con-

nects to the case-mounted suspend switch.

18) System Warning Speaker Connector (4-pin SPK)

This 4-pin connector connects to the case-mounted speaker.

19) Reset Switch Lead (2-pin RESET)

This 2-pin connector connects to the case-mounted reset switch for rebooting

your computer without having to turn off your power switch. This is a preferred

method of rebooting to prolong the life of the system’s power supply.

20) System Power LED Lead (3-pin PLED)

This 3-pin connector connects the system power LED, which lights when the

system is powered on and blinks when it is in sleep mode.
