LGA 1150 ATX motherboard for 4th Gen Intel Core

The MSI B85-G43 GAMING uses the Intel B85 chipset and an LGA 1150 socket for 4th Generation Core i7, i5, i3, Pentium and Celeron processors. It supports dual-channel DDR3 at 1600, 1333 and 1066 MHz up to 32 GB. The ATX layout provides one PCIe 3.0 x16 slot, one PCIe 2.0 x16 slot at x4, two PCIe 2.0 x1 slots and three legacy PCI slots.

Gamers and builders keeping a 4th Gen platform

Suits users who already own a 4th Gen Intel CPU and need a replacement or upgrade board with gaming-focused audio and networking. The Realtek ALC1150 codec delivers 7.1-channel output and the Killer E2205 LAN controller handles wired traffic. Builders starting a new system or requiring newer CPU generations should select a different socket and chipset.

Four SATA III and two SATA II ports decide storage

The board exposes four SATA III and two SATA II connectors for hard drives and SATA SSDs. No other storage interfaces are present, so the number of drives you can attach is fixed at six SATA devices. Confirm your drive count and type match these six ports before purchase.

Questions about this item

What case form factor and CPU socket does the B85-G43 GAMING require?

The board uses the ATX form factor and an LGA 1150 socket for 4th Generation Intel Core i7, i5, i3, Pentium and Celeron processors.

Which power connectors must be attached during installation, and which one is often missed?

Connect the 24-pin ATX main power and the 8-pin CPU power near the socket; the 8-pin CPU connector is the step most builders forget.

When should the onboard CMOS battery be replaced?

Replace the included CMOS battery when the system loses date, time or BIOS settings after being powered off.
