Socket LGA 1150 ATX board

This MSI motherboard uses the Intel B85 chipset and fits LGA 1150 processors from the fourth Core generation. The ATX layout provides four DDR3 memory slots, a full-length PCI Express 3.0 x16 slot, a second x16 slot running at x4, two PCI Express x1 slots and two legacy PCI slots. Rear I/O includes HDMI, two PS/2 ports, two USB 3.0 ports and four USB 2.0 ports.

DDR3 1600 four-slot limit

Memory runs at 1066, 1333 or 1600 across four 240-pin slots in dual-channel mode, capping total capacity at 32 GB. Only DDR3 modules are supported; other memory types will not fit or function. Choose matched kits for best stability at the highest rated speed.

Standard ATX install, legacy quirks

Mounting follows normal ATX screw positions and the 24-pin plus 8-pin power connectors sit in usual locations. The two PCI slots sit below the graphics cards, so long coolers can block them. Front-panel USB 3.0 headers are absent, so case front USB 3.0 ports will not work unless the case provides a rear-pass-through cable.

Questions about this item

How does the 32 GB DDR3 limit affect a build using all four 240-pin slots?

Each slot accepts up to 8 GB DDR3 modules running at 1066, 1333 or 1600 MT/s, so populating all four reaches the 32 GB ceiling in dual-channel mode.

What does the single PCI Express 3.0 x16 slot mean for graphics-card bandwidth?

The primary slot delivers full PCI Express 3.0 x16 bandwidth to the GPU, while the second x16-size slot is wired for x4 and the two x1 slots share PCI Express 2.0 lanes.

Will this ATX board fit a standard chassis and what power connectors are required?

The board follows ATX dimensions with a 24-pin main power connector and a 4-pin CPU power header; it mounts on standard ATX standoffs and uses the regular I/O shield cut-out.
