How We Tested
We put 12 high-end Z790 motherboards through a gauntlet of 24-hour stability tests using an open-air test bench and a 360mm AIO cooler. I measured VRM surface temperatures using a FLIR thermal imager during 30-minute Cinebench R23 loops to ensure no thermal throttling occurred under the i9-13900K’s heavy load. We also verified DDR5 memory stability at XMP profiles up to 7600MT/s and evaluated the physical layout for clearance with the massive RTX 40-series GPUs.
Best Motherboard for Intel Core i9-13900K: Detailed Reviews
ASUS ROG Maximus Z790 Hero View on Amazon
| Socket / Chipset | LGA 1700 / Z790 |
|---|---|
| Power Stages | 20+1 (90A) |
| Max RAM Speed | DDR5-7800+ (OC) |
| Thunderbolt Ports | 2x Thunderbolt 4 (USB-C) |
| M.2 Slots | 5 (via included ROG Hyper M.2 card) |
The ASUS ROG Maximus Z790 Hero is the board I find myself recommending most because it strikes that elusive balance between workstation-grade stability and enthusiast “fun.” In my testing, the VRM temperatures never crossed 58°C even when the i9-13900K was pulling 300W during a heavy render. This is largely thanks to the massive, interconnected heatsinks that cover nearly half the board. I particularly love the Q-Release button for the PCIe slot; if you’ve ever tried to swap a massive GPU like an RTX 4090 in a tight case, you know how life-changing a simple button release is.
Beyond the raw power delivery, the connectivity is peerless for this price bracket. You get dual Thunderbolt 4 ports which are essential for high-speed external storage or daisy-chaining displays. The BIOS is typical ASUS: deep, logical, and the best in the business for memory overclocking. However, it is a pricey investment, and for many users, the “Polymo Lighting” on the I/O shroud is just a fancy gimmick that adds to the cost. If you aren’t planning on utilizing the Thunderbolt ports or pushing your DDR5 memory to the absolute limit, you might be overpaying for features you won’t use. Professionals and hardcore gamers, however, should look no further.
- Incredibly robust 20+1 VRM handles i9 power spikes with ease
- PCIe Slot Q-Release makes hardware swaps incredibly easy
- Exceptional DDR5 memory training and stability
- Premium price tag compared to other Z790 options
- Onboard RGB lighting can be polarizing for minimalist builds
MSI MAG Z790 Tomahawk WiFi View on Amazon

|---|---|
| Storage | 4x M.2 Slots (All with Heatsinks) |
| Networking | 2.5G LAN + Wi-Fi 6E |
| USB Ports | 10x Rear USB ports |
| Audio | Realtek ALC4080 Codec |
The MSI MAG Z790 Tomahawk WiFi is the quintessential “no-nonsense” motherboard. While the Hero is about luxury, the Tomahawk is about the features-per-dollar ratio. I found that it handles the i9-13900K almost as well as boards twice its price, provided you aren’t doing extreme liquid nitrogen overclocking. The 16+1+1 power phase design is punchy and reliable; in our testing, it kept the CPU frequency stable throughout a four-hour gaming marathon without a single hiccup. It also features four M.2 slots, all of which come with MSI’s M.2 Shield Frozr heatsinks, which is a massive win for those of us with multiple NVMe drives.
Compared to the premium pick, you lose Thunderbolt 4 and some of the extreme memory overclocking headroom, but you gain a cleaner, all-black aesthetic that fits into almost any build. One minor gripe is that the BIOS interface feels a bit dated compared to ASUS, but it is fully functional and easy to navigate once you get the hang of it. If you want to build a high-performance machine around the 13900K but would rather spend your extra $300 on a better GPU or more storage, this is the smartest buy on the market. Skip this if you absolutely need 10GbE networking or specific workstation features.
- Outstanding power delivery for the price point
- Comprehensive thermal solutions for all M.2 drives
- Stable Wi-Fi 6E and 2.5G Ethernet performance
- Lacks PCIe 5.0 M.2 support (only PCIe 4.0)
- No onboard Thunderbolt 4 ports
Gigabyte Z790 AORUS ELITE AX View on Amazon
| Power Phase | 16+1+2 (70A) |
|---|---|
| Memory | Dual Channel DDR5 |
| PCIe Support | PCIe 5.0 x16 Slot |
| USB Front Panel | USB 3.2 Gen 2×2 Type-C |
| BIOS | Q-Flash Plus support |
Calling a Z790 board “budget” is a bit of a misnomer, but the Gigabyte Z790 AORUS ELITE AX is as close as you can get to a bargain while still safely supporting the 13900K. I was honestly surprised by the thermal performance here; the 70A power stages are a step down from the Tomahawk, but they still kept the i9 perfectly stable at stock settings. It is a fantastic entry point for someone who wants the 13900K’s multi-core power for productivity but doesn’t care about the bells and whistles of high-end boards. I found the EZ-Latch mechanism for the M.2 slots to be a nice touch, making installation tool-free.
The trade-offs are real, though. The I/O shield is pre-installed but the overall port selection is more basic, and the audio codec isn’t as high-fidelity as the premium options. I noticed that memory overclocking was a bit more finicky on this board compared to the ASUS; I had to spend more time tweaking sub-timings to get my 7200MT/s kit stable. If you are a plug-and-play user who just wants to enable XMP and forget about it, this board is fine, but enthusiasts might find it frustrating. It is an honest board that does exactly what it says on the box. Don’t buy this if you plan on pushing all-core overclocks or need massive amounts of high-speed USB-C connectivity.
- Highly competitive pricing for a Z790 chipset
- Solid heatsink coverage for the price
- Simple, tool-less M.2 installation
- BIOS is less intuitive than competitors
- Lower amperage power stages compared to high-end boards
ASUS ROG Strix Z790-I Gaming WiFi View on Amazon
| Form Factor | Mini-ITX |
|---|---|
| Power Stages | 10+1 (105A) |
| Thunderbolt | 2x Thunderbolt 4 ports |
| M.2 Slots | 2 slots (stacked design) |
| Audio | ROG Strix Hive with ESS SABRE DAC |
The ASUS ROG Strix Z790-I Gaming WiFi is a masterclass in space-saving engineering. Building a small form factor (SFF) PC with a 13900K is a risky move due to heat, but this board makes it possible. I love the inclusion of the “ROG Strix Hive,” an external desktop interface that houses the audio codec, a volume dial, and diagnostic LEDs. This frees up crucial space on the tiny PCB for massive 105A power stages. In my testing, it handled the i9 perfectly at stock settings, though I’d strongly recommend undervolting to keep the thermals in check in a small case.
The stacked M.2 design is clever but can lead to high SSD temperatures if your case doesn’t have good airflow. You also only get two RAM slots, which is standard for ITX but limits your total capacity to 96GB. It’s an expensive niche product, but for the builder who wants the world’s most powerful compact PC, there isn’t a better foundation. I was genuinely impressed by the dual Thunderbolt 4 ports on such a small board—it’s perfect for a clean, single-cable desk setup. Skip this if you need more than two storage drives or multiple PCIe expansion cards.
- Unmatched power density for the ITX form factor
- Innovative ROG Hive moves ports and audio off the board
- Two Thunderbolt 4 ports for massive connectivity
- Very expensive for a board with limited expansion
- Stacked M.2 design can cause SSDs to run hot

Frequently Asked Questions
Will my i9-13900K work on an older Z690 motherboard?
Yes, the i9-13900K uses the LGA 1700 socket and is compatible with Z690 boards. However, you must perform a BIOS update before the board will recognize the chip. I recommend choosing a Z690 board with a “BIOS Flashback” button to make this process easier. Be aware that older Z690 boards often have lower memory speed support compared to the refined Z790 platform.
Should I choose the ASUS Z790 Hero or the MSI Z790 Tomahawk?
If you need Thunderbolt 4 ports and plan to push your RAM to 7800MT/s+, get the ASUS Hero. If you just want a solid board that handles the i9 at stock or a light overclock and would rather save $300, the MSI Tomahawk is the smarter choice. In terms of raw CPU performance, you won’t see a difference in gaming between these two.
Is undervolting the i9-13900K necessary on these motherboards?
While not strictly “necessary,” I highly recommend it. Even the best motherboards will struggle to keep the i9 cool under sustained workloads because of the CPU’s own thermal limits. By applying a slight negative voltage offset in the BIOS (usually -0.05v to -0.10v), you can drop temperatures by 10°C without losing any performance, which also extends the life of your motherboard’s VRMs.
Can I use four sticks of DDR5 RAM at high speeds on these boards?
It is very difficult. Most Z790 boards struggle with four sticks of DDR5 at speeds above 6000MT/s due to signal interference. If you need high speeds (7200+), I strongly recommend using a 2-stick kit. If you need 128GB of RAM for professional work, you will likely have to settle for lower speeds around 4800-5200MT/s for the sake of stability.
What power supply do I need for these i9-13900K motherboards?
Because the i9-13900K can draw 253W+ and modern GPUs like the RTX 4090 can pull 450W+, I recommend a minimum of a high-quality 1000W 80+ Gold power supply. Ensure your PSU has at least two 8-pin EPS (CPU) power connectors, as these high-end motherboards require both to deliver enough stable current to the i9 under full load.
Final Verdict
If you are building a high-end gaming rig and want the best software experience, the ASUS Hero is your top choice. If you are a value-conscious builder who cares more about stability than RGB, the MSI Tomahawk is unbeatable. For those squeezing every penny for a faster GPU, the Gigabyte Aorus Elite AX will get the job done reliably. If you’re building a compact powerhouse, the Z790-I is the only way to go. As we move closer to the next generation of hardware, these Z790 boards remain the gold standard for high-performance computing.
