LGA 1150 micro-ATX board for 4th-gen Intel CPUs

This MSI B85M-P33 V3 motherboard fits LGA 1150 processors from the 4th generation Intel Core i7, i5, i3, Pentium and Celeron families. The Intel B85 chipset provides a compact micro-ATX layout suited to office or home builds that do not need overclocking features. It delivers the essential connectivity for a straightforward desktop system.

16 GB DDR3 dual-channel capacity

Two memory slots support dual-channel DDR3 at 1600, 1333 and 1066 MHz up to a maximum of 16 GB. That headroom covers typical multitasking and mainstream applications, while the slot count limits future expansion beyond the 16 GB ceiling. Four SATA III and two SATA II ports give six drive connections for mixed SSD and hard-drive arrays.

PCIe 3.0 x16 and legacy PCIe 2.0 x1 slots

A single PCIe 3.0 x16 slot handles one graphics card or high-bandwidth add-in card at full 3.0 speed. Two PCIe 2.0 x1 slots remain for secondary controllers such as sound cards or extra USB adapters. Onboard I/O includes four USB 3.0 ports, six USB 2.0 ports, Realtek 8111G gigabit LAN and Realtek ALC887 8-channel audio compliant with Azalia 1.0.

Questions about this item

Will my existing DDR3 1600 MHz modules work with the B85M-P33 V3?

Yes, the board supports dual-channel DDR3 at 1600, 1333 and 1066 MHz up to 16 GB total.

How can I verify the Realtek 8111G LAN is running at 1000 Mbps after installation?

Check the network adapter status in Windows or the BIOS hardware monitor; it should show a 1 Gbps link speed when connected to a gigabit switch.

Does the box include a Wi-Fi antenna or extra SATA cables?

The package contains the motherboard, a CMOS battery, one SATA cable and the rear I/O shield; no Wi-Fi antenna or additional cables are supplied.
