Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.
• Seek professional assistance before using an adapter or extension cord. These devices could interrupt the grounding circuit.
• Ensure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.
• If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer.

Product introduction
Motherboard overview
• Unplug the power cord from the wall socket before touching any component.
1
• 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.
• 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.
• Unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage to motherboard components.

ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
Correctly orient the ATX power supply plugs into these connectors and push down firmly until the connectors completely fit.
• 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 350 W. This PSU type has 24-pin and 8-pin power plugs.
• We recommend that you use a PSU with higher power output when configuring a system with more power-consuming devices or when you intend to install additional devices. The system may become unstable or may not boot up if the power is inadequate.
• If you are uncertain about the minimum power supply requirement for your system, refer to the Recommended Power Supply Wattage Calculator at http://support.
asus.com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
CPU, chassis, and AIO pump fan connectors (4-pin CPU_FAN, 4-pin CHA_
FAN1~2, 4-pin AIO_PUMP FAN)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! Do not place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan of maximum 1A (12 W) fan power.

• When an M.2 device in PCIe mode is installed onto M.2_1, PCIe x16_2 slot only runs at x1 mode and SATA6G_1 port is enabled.
• When an M.2 device in SATA mode is installed onto M.2_1, the M.2 device uses the SATA6G_1 bandwidth. SATA6G_1 port is disabled.
System panel connector (20-5 pin F_PANEL)
This connector supports several chassis-mounted functions.
Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data of the system setup information such as date, time, and system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the < Del> key during the boot process and enter BIOS setup to re-enter data.

Front panel audio connector (10-1 pin AAFP)
This connector is for a chassis-mounted front panel audio I/O module that supports either HD Audio or legacy AC`97 audio standard. Connect one end of the front panel audio I/O module cable to this connector.
• We recommend that you connect a high-definition front panel audio module to this connector to avail of the motherboard’s high-definition audio capability.
• If you want to connect a high-definition front panel audio module to this connector, set the Front Panel Type item in the BIOS setup to [HD Audio]. If you want to connect an AC’97 front panel audio module to this connector, set the item to
[AC97]. By default, this connector is set to [HD Audio].

ASUS PRIME B250-PRO
Central Processing Unit (CPU)
This motherboard comes with a surface mount LGA1151 socket designed for the 7th/6th Generation Intel i3, Pentium
®
and Celeron
®
processors.
® Core™ i7 / Core™ i5 / Core™
Unplug all power cables before installing the CPU.
• Ensure that you install the correct CPU designed for the LGA1151 socket only. DO
NOT install a CPU designed for LGA1150, LGA1155 and LGA1156 sockets on the
LGA1151 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.
• 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
LGA1151 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.

System memory
Overview
This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. A DDR4 module is notched differently from a DDR, DDR2, or DDR3 module.
DO NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.

Sockets

DIMM_B1 and DIMM_B2
• You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.
• According to Intel
®
CPU spec, DIMM voltage below 1.4V is recommended to protect the CPU.
• Due to Intel ® chipset limitation, DDR4 2400MHz memory frequency is only supported by 7th Generation Intel
®
processors. Higher memory modules will run at the maximum transfer rate of DDR4 2400MHz.
• Due to Intel
®
chipset limitation, DDR4 2133MHz and higher memory modules on 6th
Generation Intel ® processors will run at the maximum transfer rate of DDR4 2133MHz.
• Due to the memory address limitation on 32-bit Windows ® OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory, we recommend that you do any of the following:
- Use a maximum of 3GB system memory if you are using a 32-bit Windows ® OS.
- Install a 64-bit Windows ® motherboard.
OS if you want to install 4GB or more on the
- For more details, refer to the Microsoft
®
support site at http://support.microsoft.
com/kb/929605/en-us.
• Memory modules with memory frequency higher than 2133/2400 MHz and its corresponding timing or the loaded X.M.P. Profile is not the JEDEC memory standard.
The stability and compatibility of these memory modules depend on the CPU’s capabilities and other installed devices.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value.
• For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs).
