Socket LGA 2011-v3 ATX board for Intel Core i7

The MSI X99A SLI PLUS uses the Intel X99 chipset and fits CPUs with LGA 2011-v3 packaging. Four-channel DDR4 support scales to 128GB across a wide OC range from 2133 to 3333 MHz. Four PCIe 3.0 x16 slots plus two PCIe 2.0 x1 slots give room for multi-GPU or add-in cards. Ten SATA III ports, one SATA Express and one M.2 interface cover storage. Realtek ALC892 delivers 7.1 channel audio with S/PDIF. Intel I218 provides gigabit LAN. Six USB 3.0 and six USB 2.0 ports handle peripherals.

Check CPU PCIe lanes and cooler clearance

This board is limited to CPUs that support 40 PCIe lanes for full 3-way x16/x16/x8 operation; lesser lane counts change slot wiring to x16/x8 or x8/x8/x8. Verify your processor matches the LGA 2011-v3 socket and lane requirement before ordering. Ensure the chassis fits ATX dimensions and that the CPU cooler clears the socket keep-out zone. Confirm the power supply carries the necessary EPS connectors for the X99 platform. Match DDR4 modules to the qualified speed list for stability.

ATX layout with reinforced slots and rear I/O

The ATX form factor uses standard mounting holes for typical chassis. Steel-armoured PCIe x16 slots resist sag from heavy graphics cards. Rear I/O panel integrates two USB 3.0, two USB 2.0, LAN, audio jacks and S/PDIF. Four internal USB 3.0 and four USB 2.0 headers support front-panel ports. One M.2 and one SATA Express connector sit alongside ten angled SATA III ports for tidy cable routing. Package supplies the board, CMOS battery, one SATA cable and the chassis I/O back panel.

Questions about this item

What comes in the box and which essential parts must be sourced separately?

The package includes the motherboard, a CMOS battery, one SATA cable and the rear I/O shield. You must buy a compatible LGA 2011-v3 processor, DDR4 memory modules, storage drives, a power supply and a chassis.

Which memory speeds and capacities does this board support for a high-capacity build?

It supports quad-channel DDR4 at 2133 MHz natively and up to 3333 MHz when overclocked, with a maximum of 128 GB across four slots.

What does the four-slot PCIe 3.0 x16 layout mean for a three-way graphics setup?

With a 40-lane CPU the board can run three cards at x16/x16/x8; with a 28-lane CPU the split becomes x8/x8/x8.
