2.3 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Quad /Core™2 Extreme / Core™2 Duo / Pentium® Extreme / Pentium® D / Pentium® 4 Processors 2- • Make sure that all power cables are unplugged before installing the CPU. • If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability. • Due to the chipset limitation, we recommend you use FSB 800MHz CPU or above.
2.3.1 Installing the CPU To install a CPU: Locate the CPU socket on the motherboard. P5K/EPU 1. ® P5K/EPU CPU Socket 775 Before installing the CPU, make sure that the cam box is facing towards you and the load lever is on your left. 2. Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab. Retention tab Load lever A PnP cap B This side of the socket box should face you.
4. Lift the load plate with your thumb and forefinger to a 100º angle (A), then push the PnP cap from the load plate window to remove (B). B A Load plate Alignment key 5. Position the CPU over the socket, making sure that the gold triangle is on the bottom‑left corner of the socket then fit the socket alignment key into the CPU notch. CPU notch Gold triangle mark The CPU fits in only one correct orientation.
2.3.2 Installing the CPU heatsink and fan ® The Intel LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel®‑certified multi‑directional heatsink and fan. • Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
2. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place.

Never connect a USB cable to the IEEE 1394a connector. Doing so will damage the motherboard! You can attach a FireWire/1394 cable to this connector if your chassis suppots the front panel IEEE1394 port. Connect the 1394 cable to ASUS Q-Connector (1394, red) first, and then install the Q-Connector (1394) to the 1394 connector onboard. The IEEE 1394a module cable is purchased separately. 6.
7. 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.
• • • • • • 9. For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum power of 400 W. Do not forget to connect the 4-pin ATX12V power plug; otherwise, the system will not boot.
