What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about MSI X299 Tomahawk AC

  • Excellent value for an X299 platform motherboard, often described as a 'budget' HEDT option
  • High build quality with 'built like a tank' construction and reinforced PCIe slots
  • Unique and attractive aesthetics, especially the all-white design of the Arctic variant
  • Feature-packed for the price, including M.2 Shield Frozr heatsinks and BIOS Flashback
  • User-friendly convenience features like on-board power/reset buttons and a rear CMOS reset button
  • Comprehensive storage options with support for multiple RAID configurations (RAID 0, 1, 5, 10)
  • Robust bundled software system for system tuning and 'X-Boost' performance presets

What customers don't like about MSI X299 Tomahawk AC

  • Underwhelming VRM and power delivery compared to higher-end X299 boards, featuring only a single 8-pin connector
  • Not recommended for hardcore or extreme overclocking due to power and thermal constraints
  • Lack of 'star power' or highly innovative standout features compared to competitors like ASUS ROG Strix
  • Limited rear I/O connectivity, specifically a lower number of USB ports compared to other boards in the class
  • VRM cooling can be a concern under heavy, sustained loads
  • No support for 4-way SLI configurations

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.
