as their operating system. It natively supports hard drives larger than
2.2TB in 64-bit, with full storage space utilization, helping deliver far more
exciting computing than traditional BIOS version. The exclusive EZ Mode
displays frequently-accessed setup info. while the Advanced Mode is
for experienced performance enthusiasts that demand far more intricate
system settings.
1-3Chapter 1: Product introduction
ASUS Anti-Surge Protection
This special design prevents expensive devices and the motherboard
from damage caused by power surges from switching power supply
(PSU).
ASUS EPU
ASUS EPU is a unique power saving technology that detects the current
system loadings and adjusts the power consumption in real time.
AI Suite II
With its fast user-friendly interface, ASUS AI Suite II consolidates all the
exclusive ASUS features into one simple to use software package. It
allows you to supervise overclocking, energy management, fan speed
control, and voltage and sensor readings. This all-in-one software offers
diverse and ease to use functions, with no need to switch back and forth
between different utilities.
Fanless Design: stylish heatsink solution
The stylish Heatsink features a 0-dB thermal solution that offers users a
noiseless PC environment. The beautifully curved ns not only upgrade
the visual enjoyment for motherboard users, but also effectively cools
down hot airows generated by the northbridge chipset. Combined with
usability and aesthetics, the ASUS stylish Heatsink will give users an
extremely silent and cooling experience with the elegant appearance!
ESD
Protect Your Computer with ESD Guards. Electrostatic discharge
(ESD) conditions can happen while plugging or unplugging any USB
peripherals-causing damage to the computer. ASUS ESD Guards clamp
the ESD voltage and shunt the majority of the ESD current away for a
more reliable computing environment.
Low EMI
A special low-radiation design shields you from harmful electromagnetic
exposure by eliminating 50% of radiation.
1. Radiation Deduction Design minimizes harmful electromagnetic
radiation output with exclusive circuit design to cancel electrical charge.
2. The Radiation Moat Design effectively blocks radiation to prevent
discharge spread.
Fan Xpert
ASUS Fan Xpert intelligently allows you to adjust the CPU and chassis
fan speeds according to different ambient temperatures caused by
different climate conditions in different geographic regions and your PC’s
loading. The built-in variety of useful proles offer exible controls of fan
speed to achieve a quiet and cool environment.
ASUS P8H61-M LX1-4
ASUS MyLogo2™
This feature allows you to convert your favorite photo into a 256-color
boot logo for a more colorful and vivid image on your screen.
ASUS CrashFree BIOS 3
ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to
restore a corrupted BIOS le using the bundled support DVD or USB
ash disk that contains the latest BIOS le.
ASUS EZ Flash 2
ASUS EZ Flash 2 is a utility that allows you to update the BIOS without
using an OS-based utility.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings
when the system hangs due to overclocking failure. C.P.R. eliminates the
need to open the system chassis and clear the RTC data. Simply shut
down and reboot the system, and the BIOS automatically restores the
CPU parameters to their default settings.
ErP ready
The motherboard is European Union´s Energy-related Products (ErP)
ready, and ErP requires products to meet certain energy efciency
requirements in regards to energy consumptions. This is in line with
ASUS vision of creating environment-friendly and energy-efcient
products through product design and innovation to reduce carbon
footprint of the product and thus mitigate environmental impacts.
1-5Chapter 1: Product introduction
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.
Standby Power LED
The motherboard comes with a standby power LED that lights up to indicate that the system
is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down
the system and unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard LED.

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.
Place this side towards
the rear of the chassis

ASUS P8H61-M LX1-8
1.6 Central Processing Unit (CPU)
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.
To prevent damage to the socket pins,
do not remove the PnP cap unless
you are installing a CPU.
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.

8. Insert the load lever under the retention
tab.
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.
