Z77 Chipset LGA 1155 ATX Motherboard

The MSI Z77A-G43 is an ATX motherboard built on the Intel Z77 chipset for LGA 1155 processors. It supports Core i7, i5 and i3 CPUs with integrated graphics. Four 240-pin slots accept DDR3 memory up to 2667 MT/s when overclocked, with a maximum capacity of 32 GB in dual-channel mode.

Suits Legacy Builds and Upgrades

This board suits builders repairing or upgrading an existing LGA 1155 system who need SATA 6 Gb/s and USB 3.0 connectivity. It provides one PCI Express 3.0 x16 slot, one PCI Express 2.0 x16 slot running at x4, two PCI Express x1 slots and three legacy PCI slots. Users requiring a newer CPU socket, different memory type or M.2 storage should select a different motherboard.

LGA 1155 Socket Defines Compatibility

The LGA 1155 socket is the single specification that decides whether this is the right part. Only Intel Core i7, i5 and i3 processors designed for this socket will install and operate. Chipset features such as SATA RAID 0, 1, 5, 10, 8-channel Realtek ALC892 audio and Realtek 8111E Gigabit LAN are secondary to the socket requirement.
