Product introduction

1.1
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.
1.2
Motherboard overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits.
Unplug the power cord before installing or removing the motherboard. Failure to do so can
cause you physical injury and damage to motherboard components.
1.2.1
Placement direction
When installing the motherboard, 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.
1.2.2
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.

ASUS B85-PLUS
Unplug all power cables before installing the CPU.
•
•
Ensure that you install the correct CPU designed for the LGA1150 socket only. DO
NOT install a CPU designed for LGA1155 and LGA1156 sockets on the LGA1150
socket.
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
LGA1150 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.
