MSI unveiled the X99A-SLI motherboard. This is not to be confused with the X99A-SLI PLUS the company launched in its first wave of socket LGA2011v3 motherboards, in 2015. The new board features a few modern connectivity features, such as 32 Gb/s M.2 slots, a U.2 connector, and USB 3.1 with type-C. The board also comes with support for Core i7 "Broadwell-E" processors, out of the box. Built in the standard ATX form-factor, the board draws power from a combination of 24-pin ATX and 8-pin EPS connectors, and uses an 8-phase VRM to condition it for the CPU.

Expansion slots include three PCI-Express 3.0 x16, and two PCIe 2.0 x1. Storage connectivity includes one 32 Gb/s M.2 slot, a 32 Gb/s U.2 port, one 10 Gb/s SATA-Express connector, and a total of twelve SATA 6 Gb/s ports. Among the USB connectivity are two 10 Gb/s USB 3.1 ports, from which one is type-C, and eight other USB 3.0 ports (four on the rear panel, four by headers). 8-channel HD audio, and an Intel controller-driven gigabit Ethernet connection make for the rest of it. This could be one of MSI's more affordable socket LGA2011v3 boards.
