Installation Guide
Power supply
The QZ35Q ATX motherboard requires a 12V ATX power supply. Although most power supplies
generally meet the specifications required by the CPU, some are inadequate. Make sure that the power
supply you select can provide a 2-Amp current supply on a 5V standby rail.
It is strongly recommended that you use a high-quality power supply that meets 12V ATX power supply
specification 1.1 or above. It is also required that the 12V 4-pin power connection (J41) be used for
high-load configurations. In areas where power transmissions are present, you may choose to install a
line filter to shield the computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.
Connecting the power supply
1. Ensure that the AC power cord is disconnected.
2. Attach the 24-pin main power supply connector to the 24-pin ATX power connector on the
motherboard (J40).
3. Insert the 4-pin power supply into the 4-pin ATX 12V connector (J41).
4. Connect the AC power cord.
Processor support
The motherboard supports the following Intel® embedded processors.
Intel Core™ 2 Duo E6400
Intel Core 2 Duo E4300
Intel Pentium® Dual-Core E2160
Intel Celeron® 440
If a processor you are interested in is not mentioned in this list, refer to the Procelerant Endura Q35

CPU and active heatsink Installation
Refer to the installation instructions accompanying the processor, or visit the Intel web site to view the
Boxed Intel® Processors in the 775-land Package - Integration Video.
If you purchase a CPU without active heatsink, make sure that you use only an Intel-certified, multi-
directional heatsink and fan.

ARNING
Be careful not to bend the pins when installing or removing the CPU. This is a common cause of system
failure. To avoid bending the pins, handle the CPU with extreme care and insert it straight down into the
CPU socket. When removing the CPU, pull it straight up out of the socket.
