7. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V) These connectors are for an ATX power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. • Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will not boot up. • Use a PSU with a minimum power rating of 300 W on this motherboard. Use of a PSU with a higher power output is recommended when configuring a system with more power‑consuming devices. The system may become unstable or may not boot up if the power is inadequate.

Chassis intrusion connector (4-1 pin CHASSIS) This connector is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event. By default, the pins labeled "Chassis Signal" and "Ground" are shorted with a jumper cap. Remove the jumper caps only when you intend to use the chassis intrusion detection feature. +5VSB_MB Chassis Signal GND ® P5VD2-VM SE CHASSIS (Default) P5VD2-VM SE Chassis intrusion connector 1-32 Chapter 1: Product introduction
