The Intel Core i9-14900K is a 24-core processor with 8 Performance-cores and 16 Efficient-cores, and it reaches boost clocks of up to 6.0 GHz under Intel’s Thermal Velocity Boost. The processor operates on the LGA 1700 socket and draws up to 253 W under PL2 turbo conditions. A motherboard paired with this processor must deliver stable power beyond that figure, since sustained multi-core workloads and manual overclocking push current draw higher than the rated specification.
Motherboard selection affects three areas of an i9-14900K build: power delivery, memory bandwidth, and I/O capacity. The VRM (voltage regulator module) determines how much current the board supplies to the CPU without thermal throttling. The memory controller and DIMM layout determine achievable DDR5 speeds. The chipset and PCB design determine how many PCIe 5.0 lanes, M.2 slots, and USB ports the system can use at once. Intel Z790 is the only mainstream chipset that unlocks full overclocking support for the i9-14900K, so every board in this guide uses that chipset.
This guide reviews six Z790 motherboards for the Intel Core i9-14900K: the MSI MAG Z790 Tomahawk MAX WiFi, the ASUS ROG Maximus Z790 Dark Hero, the Gigabyte Z790 AORUS Elite X, the Gigabyte Z790 AORUS Master X, the MSI MPG Z790 Carbon WiFi II, and the ASRock Z790 Taichi Lite. Each entry covers the board’s specifications, how those specifications interact with the i9-14900K, and how the board compares with the other five options.
Each section that follows includes a full specification table alongside separate pros and cons lists, so the comparison points are visible at a glance rather than buried in prose. The final section explains how to weigh VRM quality, memory support, storage layout, and connectivity when choosing among these boards for an i9-14900K build.
Best Motherboards for Intel i9-14900K CPU
MSI MAG Z790 Tomahawk MAX WiFi
CHECK PRICE
PROS
CONS
The MSI MAG Z790 Tomahawk MAX WiFi is an ATX motherboard built on the Intel Z790 chipset for the LGA 1700 socket. MSI positions it as a mainstream gaming board rather than an extreme-overclocking flagship, and its specification sheet reflects that positioning: solid core features with fewer premium extras than the higher-tier boards in this guide.
The board uses a 16+1+1 Duet Rail power design with dual 8-pin CPU power connectors and a Mirrored Power Arrangement layout. Four DDR5 DIMM slots support up to 192 GB of memory, with overclocked speeds rated up to 7800+ MT/s. Storage includes four M.2 slots protected by M.2 Shield Frozr heatsinks and eight SATA III ports. Expansion consists of one PCIe 5.0 x16 slot, one PCIe 4.0 x16 slot, and one PCIe 3.0 x1 slot. Networking runs through 2.5 GbE LAN and a Wi-Fi 7 module with Bluetooth 5.4. The rear I/O carries a mix of USB 3.2 Gen 2×2, Gen 2, and Gen 1 ports, and audio runs through a Realtek ALC4080 codec with 7.1-channel output.
With the i9-14900K, the 16+1+1 VRM handles the processor’s stock 253 W PL2 turbo load without issue, and the dual 8-pin EPS connectors supply enough current for daily use and moderate all-core overclocking. The board is not built for extreme or sub-ambient overclocking, since its phase count and current rating trail the 20+1+2 and 24+1+2 designs found on the ASUS ROG Maximus Z790 Dark Hero, the Gigabyte Z790 AORUS Master X, and the ASRock Z790 Taichi Lite. Against the Gigabyte Z790 AORUS Elite X, the Tomahawk MAX WiFi offers a comparable feature set at a similar price point, with the Elite X holding a slight edge in rear I/O variety and PCIe UD Slot X reinforcement.

ASUS ROG Maximus Z790 Dark Hero
CHECK PRICE
PROS
CONS
The ASUS ROG Maximus Z790 Dark Hero is an ATX motherboard from the ROG Maximus flagship line, built on the Intel Z790 chipset for LGA 1700 processors. ASUS designed it as a refresh of the ROG Maximus Z790 Hero, with Wi-Fi 7 support and expanded M.2 capacity as the primary changes.
Power delivery consists of a 20+1+2 phase configuration, broken down into 20 VCore phases and 1 integrated-graphics phase managed by a Renesas RAA229131 controller, plus 2 auxiliary phases. Each VCore phase uses a 90 A Intersil ISL99390 Smart Power Stage, giving the board a combined current capacity suited to sustained high-power workloads. Dual ProCool II 8-pin EPS connectors feed the VRM. Four DDR5 DIMM slots support up to 192 GB of memory with overclocking rated to 8000 MHz. The board includes five M.2 slots, one running at PCIe 5.0 x4 and four at PCIe 4.0 x4, which removes the need for expansion cards to reach high-speed storage capacity. Connectivity includes two Thunderbolt 4 ports and a Wi-Fi 7 module with a directional Q-Antenna.
The 20+1+2 VRM gives the i9-14900K sustained current under all-core AVX workloads without phase throttling, and Tom’s Hardware confirmed the board’s 20 90A Intersil ISL99390 SPS MOSFETs support the processor without concern, with cooling limits reached before power delivery becomes a bottleneck. Compared with the MSI MAG Z790 Tomahawk MAX WiFi and Gigabyte Z790 AORUS Elite X, the Dark Hero provides a materially stronger VRM and more M.2 slots, positioning it above those two boards for overclocking headroom. Against the Gigabyte Z790 AORUS Master X and ASRock Z790 Taichi Lite, the Dark Hero’s phase count is comparable to the Master X and lower than the Taichi Lite’s 24+1+2 design, though all three sit in the same premium tier and differ mainly in networking and expansion extras rather than raw power delivery.

How to Choose a motherboard for i9 14900K
Choosing a motherboard for the i9-14900K starts with the VRM: select a board rated for at least 16 phases with power stages of 80 A or higher, since the processor’s 253 W PL2 turbo load requires sustained current beyond what lower-end boards supply. A board with a 20-phase or higher VRM, such as the ASUS ROG Maximus Z790 Dark Hero, the Gigabyte Z790 AORUS Master X, or the ASRock Z790 Taichi Lite, adds headroom for all-core overclocking and reduces VRM operating temperature under sustained load.
Memory support matters next. Every board in this guide uses four DDR5 DIMM slots and supports up to 192 GB of total memory, but overclocked speed ratings vary from roughly 7800 MT/s to 8266 MT/s depending on the board’s PCB layout and memory trace design. A higher-rated board reduces the risk of instability when running fast DDR5 kits at their rated XMP profile alongside an overclocked i9-14900K.
Storage and expansion requirements depend on the build’s intended use. A board with five M.2 slots, such as the ASUS ROG Maximus Z790 Dark Hero, the Gigabyte Z790 AORUS Master X, the MSI MPG Z790 Carbon WiFi II, or the ASRock Z790 Taichi Lite, accommodates multiple NVMe drives without relying on SATA storage. A board with a native PCIe 5.0 x4 M.2 slot supports the fastest available consumer SSDs without splitting lanes from the primary graphics card slot. Builds that prioritize SATA-based storage arrays should favor boards with higher SATA port counts, such as the ASRock Z790 Taichi Lite or MSI MAG Z790 Tomahawk MAX WiFi, both listing eight SATA III ports.
Form factor and case compatibility narrow the remaining choice. ATX boards such as the MSI MAG Z790 Tomahawk MAX WiFi, ASUS ROG Maximus Z790 Dark Hero, Gigabyte Z790 AORUS Elite X, and MSI MPG Z790 Carbon WiFi II fit standard mid-tower cases. E-ATX boards such as the Gigabyte Z790 AORUS Master X and ASRock Z790 Taichi Lite require a case with sufficient motherboard tray width and standoff support. Finally, connectivity needs, including Thunderbolt 4, Wi-Fi 7 versus Wi-Fi 6E, and LAN speed, should match the intended use case: content creators and users connecting high-bandwidth external displays or storage benefit from Thunderbolt 4 support on the Dark Hero, Master X, or Taichi Lite, while networking-focused builds gain more from the 5 GbE LAN on the MSI MPG Z790 Carbon WiFi II.
