1.4 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due to
static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.

1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
Ensure that you unplug the power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard components.
1.5.1 Placement direction
When installing the motherboard, ensure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.5.2 Screw holes
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.

P8P67 LE
P8P67 LE CPU socket LGA1155
The motherboard comes with a surface mount LGA1155 socket designed for the Intel®
Second Generation Core™ i7 / Core™ i5 / Core™ i3 processors.
Unplug all power cables before installing the CPU.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the
socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing,
or if you see any damage to the PnP cap/socket contacts/motherboard components.
ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1155 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.
1.6.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2. Press the load lever with your thumb (A),
and then move it to the right (B) until it is

released from the retention tab.
To prevent damage to the socket pins,
do not remove the PnP cap unless
you are installing a CPU.

6. Apply some Thermal Interface Material
to the exposed area of the CPU that the
heatsink will be in contact with, ensuring
that it is spread in an even thin layer.
Some heatsinks come with preapplied thermal paste. If so, skip this
step.
The Thermal Interface Material is
toxic and inedible. DO NOT eat it. If
it gets into your eyes or touches your
skin, wash it off immediately, and seek
professional medical help.
7. Close the load plate (A), and then push
down the load lever (B), ensuring that
the front edge of the load plate slides
under the retention knob (C).
8. Insert the load lever under the retention
tab.
ASUS P8P67 LE1-12
1.6.2 Installing the CPU heatsink and fan
The Intel® LGA1155 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, ensure that you use only Intel®-certied
multi-directional heatsink and fan.
• Your Intel® LGA1155 heatsink and fan assembly comes in a push-pin design and
requires no tool to install.
• Use an LGA1155-compatible CPU heatsink and fan assembly only. The LGA1155 socket
is incompatible with the LGA775 and LGA1366 sockets in size and dimension.
If you purchased a separate CPU heatsink and fan assembly, ensure that you have
properly applied Thermal Interface Material to the CPU heatsink or CPU before you install
the heatsink and fan assembly.
Ensure that you have installed the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed
CPU, ensuring that the four fasteners match
the holes on the motherboard.
Orient the heatsink and fan assembly
such that the CPU fan cable is closest to
the CPU fan connector.
2. Push down two fasteners at a time in a
diagonal sequence to secure the heatsink
and fan assembly in place.
