We have an extended and aggressively designed shroud covering the VRM and Rear IO ports. The heavy aluminum shroud on this motherboard features a black and gray color contrast with prominent MSI branding on the IO Panel and “MAG” on the top heatsink. Notably, these are not separate shrouds but a single piece of aluminum heatsink serving both as a shroud and for heat exchange.

The motherboard features massive, single-piece aluminum heatsinks with a cutout design and gray thermal pads rated at 7W/mK. Unlike the GIGABYTE Z490 AORUS PRO AX, there’s no heat pipe, but the finned design is notable. While understandable for the MAG series, adding a single 6mm or 8mm heat pipe could have been beneficial, especially considering the price range.

The MSI MAG Z490 Tomahawk motherboard employs 12 + 1 +1 DUET RAIL POWER SYSTEM. Don’t get confused with the wording here as we actually have 6+1 power phases with two power stages combined in a single power phase. We have 14 chokes with 12 capacitors. 6 phases are going to the CPU socket. 1 phase (the rightmost on the top) is going to the GT whereas 1 phase (lowermost on the side) is going to the SA (System Agent).

MSI is using the ON NCP81229 PWM controller. The NCP81229 is a dual rail, six + one phase buck solution. The multi−phase rail control system is based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing. The controller ensures swift response to dynamic loads, cost reduction, and aligns with Intel’s IMVP8 Specifications. It supports adjustable switching frequency, digitally stabilized frequency, ultrasonic operation, and features a PSYS input monitor (SVID address 0D).

The MSI MAG Z490 Tomahawk is using NCP302155 power stages. Two of these stages are combined in a single power phase. The phases are rated for 55A each. The motherboard has over-voltage protection to safeguard from short-circuit damage to the components on the motherboard. MSI has placed a thermal sensor on the VRM allowing the temperature readout in the hardware monitor.

The MSI MAG Z490 Tomahawk is using UNIKc P06P03A for a single-phase PWM with the driver. For that, we have MOSFET configuration in the solution of 2 On Semiconductor NTMFS4C029N in a two-low one-high (NTMFS4C024N). The NTMFS4C029N is rated for 30V at 46A whereas the NTMFS4C024N has a rating of 30V, 78A.

Power Connectors (Image By Tech4Gamers)

The MSI MAG Z490 Tomahawk has 8+4 CPU power connectors positioned on the top left for added power during overclocking, particularly beneficial for Intel Core i9 10900 and 10850 variants. These connectors can handle a maximum power draw of 540W (45A). The Core Boost technology ensures fast and precise current delivery to the CPU, enhancing stability during heavy transient loads and overclocking.

DIMM slots (Image By Tech4Gamers)

The MSI MAG Z490 Tomahawk motherboard features 4 non-steel-reinforced DIMM slots in a dual-channel configuration. Both ends of the slots open for RAM installation/removal. The maximum capacity is 128GB (32GB per DIMM slot), supporting a maximum frequency of 5000 MT/s (OC). The motherboard is compatible with non-ECC Unbuffered DIMM memory modules. Let’s take a look at the top side’s connectivity provisions.

The MSI MAG Z490 Tomahawk has a single 4-pin PWM fan header above the CPU socket. On the top right, it features two RGB headers: JRGB2 (12V, max 3A) for up to 3 meters of 5050 RGB LED strips and JRAINBOW2 (5V, max 3A) for WS2812B Addressable RGB LED strips with 75 LEDs. The motherboard itself boasts 29 LEDs under the chipset cover, supporting MSI Mystic Light for customizable lighting modes with 16.8M colors.

The fan headers on the MSI MAG Z490 Tomahawk are driven by the nuvoTon 3961S controller. I was not able to find any credible data spec sheet on these controllers for more details. We have two 4-pin PWM fan headers here on the right side. One is dedicated to the pump of the liquid cooling solution rated for 2A, whereas the other is labeled Sys_FAN6, implying its use for the fan control.

The user can connect the fan to the pump header as well. Next, we have EZ Debug LEDs and a 24-pin ATX connector for the motherboard power. Next, we have a USB Type-C front panel port labeled as JUSB4.

The MSI MAG Z490 Tomahawk lacks a traditional Debug LED with error codes, instead opting for a budget-oriented troubleshooting system with four white LEDs labeled BOOT, VGA, DRAM, and CPU. The right-angled USB 3.0 front panel connector and 4x SATA 6.0 ports are followed by two 4-pin PWM fan headers at the bottom. The motherboard supports RAID 0, RAID 1, RAID 5, and RAID 10. Mounting holes feature double ESD protection for enhanced grounding. A DIP switch near SYS_FAN4 allows users to toggle LED lighting on and off.

SATA 6.0 ports
Lower side (Image By Tech4Gamers)

It is time to take a look at the connectivity options on the lower side of the motherboard. Starting from the right there is a front panel connector labeled as JFP1. We have 3-pin and 5-pin Thunderbolt Add-In headers. The Thunderbolt Add-In card is not included and needs to be purchased separately if needed.

Next, we have two more SATA 6.0 ports followed by a TPM header. Then we have two USB 2.0 9-pin headers. The MSI MAG Z490 Tomahawk motherboard utilizes a nuvoTon NUC126NE4AE controller and GL850G hub for USB connectivity. The NUC126NE4AE operates at up to 72 MHz and features a crystal-less USB 2.0 FS interface. The GL850G hub complies with USB 2.0 specifications.

The motherboard includes well-implemented headers for RGB lighting, with two each for 3-pin and 4-pin types, along with two 4-pin PWM fan headers. It also features a front-panel audio header and a full-length chipset cover with elegant stenciling in black and gray. is printed on the cover. It was a bit surprising to see the push pin style being used to connect the cover to the PCB.

There is another 4-pin PWM fan header located below the IO shroud.

PCIe Hardware

The MSI MAG Z490 Tomahawk comes with 4 PCIe slots. The top slot is steel reinforced and is electrically connected to the CPU socket and taking 16 lanes from the CPU. Here is the configuration information of these slots:

  • 1x PCIe 3.0 x16 slot (from CPU)
  • 1x PCIe 3.0 x16 slot (from PCH, supports x4 mode)
  • 2x PCIe x1 slots (from PCH)

The MSI MAG Z490 Tomahawk supports 2-Way AMD CrossFire™ technology. It features an enlarged PCI-e clip for easier device swapping, and the PCI Express Steel Armor slot, secured with extra solder points, ensures the stability and safety of heavy graphics cards while shielding against electromagnetic interference. PCIe 4.0 readiness is facilitated by the IDT6V4 1801BN clock generator, strengthening signal strength and optimizing PCB layout for higher bandwidth and transfer speeds, although PCIe 4.0 is not supported on Comet Lake CPUs.

M.2 Port

The MSI MAG Z490 Tomahawk Gaming motherboard has two M.2 ports using PCIe Gen 3 interface.

The MSI MAG Z490 Tomahawk features M.2 SHIELD FROZR thermal protection for both M.2 ports, ensuring optimal SSD performance. The top M.2 port supports PCIe 3.0 x4 and SATA 6Gb/s, accommodating 2242/2260/2280/22110 storage devices. The second M.2 port supports PCIe 3.0 x4 and SATA 6Gb/s, handling 2242/2260/2280 storage devices. Note that installing an M.2 SATA SSD in the M2_1 slot renders SATA port 2 unavailable, and using M.2 SATA/PCIe SSD in the M2_2 slot makes SATA ports 5 and 6 unavailable.

For the purpose of to-the-point testing, we disabled the MSI Core enhancement to stay with the Intel defaults. On stock, all the settings were left at Auto except the DRAM voltage and timings. We have used Blender Benchmark on stock and overclocked settings for the thermals and stability. CORSAIR Link software was used to take a reading of the power consumption.

The average temperature was 58.75°C with an ambient of 15.9°C as compared to 65.75°C with an ambient of 19.5°C on GIGABYTE Z490 AORUS PRO AX. The maximum power package was 130.937 as compared to the package power of 134.475W on the GIGABYTE board. The MSI board is not aggressively pouring in more voltage than needed, unlike the GIGABYTE motherboard.

I was able to overclock the chip with all cores on 5.1GHz using 1.379V on the GIGABYTE motherboard. Surprisingly, the MSI MAG Z490 TOMAHAWK has achieved the same voltage across all cores on Auto settings which is quite impressive. The result was the same as the manual voltage. I did not tweak the Load Line Calibration.

WARNING: Be wary of potential VRM thermal issues under heavy overclocking on the MSI MAG Z490 Tomahawk.

Under Blender Benchmark the average temperature was 78.87°C at an ambient of 15.1°C. The maximum power on the package was 187.478W. GIGABYTE motherboard does well under the overclocking scenario in terms of the thermals.

Thermal Imaging

We have used the Hti HT18 Thermal camera to record the thermals of the VRM area of the motherboard under load using blender benchmark on the stock and with an overclock scenario.

The maximum temperature on the MOSFETs was 51.9°C with an ambient of 15.9°C. With 5.1GHz all core under Blender Benchmark testing, the maximum temperature on the MOSFETs was 64°C with an ambient of 15.1°C. The MOSFET thermals are a bit higher than what we saw on the GIGABYTE Z490 AORUS PRO AX but not high to caution the users as they are still a solid mark.

Should You Buy It?

After hours of testing, I was able to evaluate who the MSI MAG Z490 Tomahawk is designed for.

Buy It If:

 ✅You are looking for a reasonably priced Z490 motherboard: The MSI MAG Z490 Tomahawk brings the features of the Z490 chipset at a comparatively lower price tag.

✅You want USB 3.2 Gen 2×2 connectivity: Unlike other motherboards in this price bracket, the MSI MAG Z490 Tomahawk comes with a USB 3.2 Gen 2×2 port for 20Gbps connectivity. 

Don’t Buy It If:

You want WiFi Connectivity: The MSI MAG Z490 Tomahawk does not come with WiFi connectivity.


This is the second motherboard in the Z490 chipset which have reviewed as we took a look at the GIGABYTE Z490 AORUS PRO AX earlier. The MSI MAG Z490 Tomahawk motherboard, part of the MGA series, strikes a balance between affordability and features. Positioned in the entry to the mid-range segment, it’s a durable and feature-rich option without the frills. While not enthusiast-grade, it offers value for its price, making it a purposeful choice for users seeking a reliable gaming motherboard.

So, what the numbers are saying about the actual performance of the motherboard? The motherboard is eating anything I throw at it and it is crunching those numbers for sure. I was blown away by the stock results as on many occasions the results were better than the other motherboard we have tested.

The VRMs will handle the load easily and the thermals are fine as well. For Core i9 CPUs, I should be on the lookout when overclocking to ensure that thermals remain within the optimal range. MSI has done a good job with their UEFI/BIOS programming as this motherboard is not pumping unnecessary voltage on Auto settings on stock and even on overclocking scenarios. All-in-all, this motherboard has performed remarkably well all around.
