Verdict

The MSI X299 Tomahawk AC is an ATX motherboard built on the Intel X299 chipset and LGA 2066 socket, supporting Intel Core X-series processors with 8 DIMM slots for up to 128GB of quad-channel DDR4 memory at speeds exceeding 4133MHz (OC). Key specifications include four PCIe 3.0 x16 slots supporting 3-way SLI/CrossFire, dual Turbo M.2 slots with M.2 Shield FROZR, a dedicated U.2 port, and eight SATA 6Gb/s ports for extensive storage configurations. Its primary advantages are its robust 'Steel Armor' design, integrated Intel Wireless-AC 8265 with Bluetooth 4.2, and premium Audio Boost 4 technology; however, its overclocking potential is somewhat limited by a single 8-pin power connector and a less sophisticated VRM compared to higher-end X299 models.
