Quick Answer: Does the Tomahawk B450 Have Wifi?
No, the standard MSI MPG B450 Tomahawk does not have built-in WiFi. It relies on a wired Gigabit Ethernet port for networking. The same is generally true for the B450 Tomahawk MAX, which also ships without integrated wireless on most variants. If you need wireless connectivity, you will need to add a PCIe WiFi adapter, a USB WiFi dongle, or use an external bridge. Some regional or special editions may include WiFi, so always check the exact model name and the box label before buying.
What Is the MSI MPG B450 Tomahawk?
The MSI MPG B450 Tomahawk is a mid-range ATX motherboard built on the AMD B450 chipset. It was designed for Ryzen processors and became one of the most popular boards in its price bracket because of its solid VRM cooling, generous feature set, and attractive price-to-performance ratio. It supports Ryzen 1000 through 5000 series CPUs (with appropriate BIOS updates), DDR4 memory, PCIe 3.0 graphics, and multiple storage options.
Key features include:
- AMD B450 chipset with AM4 socket
- Support for high-speed DDR4 memory
- Multiple PCIe slots for GPUs and expansion cards
- Gigabit LAN powered by a Realtek controller
- M.2 slots for fast NVMe storage

Because it targets budget-conscious builders, MSI chose to prioritize core performance features over built-in wireless. That decision keeps the cost down but leaves WiFi as an add-on for users who need it.
Does the Tomahawk B450 Have Wifi? (Detailed Answer)
To be precise, the standard MSI MPG B450 Tomahawk and the MSI MPG B450 Tomahawk MAX do not include an integrated WiFi module or Bluetooth in their base configurations. The rear I/O panel includes a Gigabit Ethernet port, USB ports, audio jacks, and display outputs (depending on CPU), but no WiFi antenna connectors.
That said, MSI has released various regional bundles and special editions over the years. Some retailers may stock a “WiFi” variant or include a bundled PCIe adapter in the box. The only way to be certain is to read the exact product name and the specification sheet. If the name does not explicitly say “WiFi,” assume it does not have wireless.
B450 Tomahawk MAX and WiFi
The MAX version improves BIOS flash capability and memory compatibility, but it still does not add built-in WiFi in most cases. It is a better choice for Ryzen 3000 and 5000 CPUs out of the box, yet wireless remains an aftermarket addition.
How to Identify a WiFi Edition
Look for keywords like “WiFi,” “AC,” or “AX” in the product title. Also check the rear I/O for two small gold antenna connectors. If those connectors are absent, the board has no integrated wireless.

As you can see, the standard Tomahawk B450 is a wired-only board. If wireless is a must-have, you either need a different model or an add-on adapter.
How to Check If Your Motherboard Has WiFi
Before buying adapters, confirm whether your current board already supports wireless. Here is a simple checklist:
- Read the exact model name printed on the board and the box.
- Inspect the rear I/O panel for two small gold antenna ports.
- Open Device Manager in Windows and look under “Network adapters” for a WiFi device.
- Check the BIOS for any wireless or Bluetooth settings.
- Search the model number plus “specs” on the manufacturer’s website.
If none of these reveal a wireless module, your board does not have WiFi. This is the most common situation with the Tomahawk B450.
Step-by-Step: Adding WiFi with a PCIe Adapter
A PCIe WiFi adapter is the most reliable way to add wireless to the B450 Tomahawk. It installs into a spare PCIe slot and often includes external antennas for better signal.
What You Need
- PCIe x1 or x16 WiFi adapter (WiFi 5 or WiFi 6 recommended)
- Screwdriver
- Antenna base and antennas (usually included)
- Latest driver from the adapter manufacturer
Installation Steps
- Power off the PC and unplug it from the wall.
- Open the side panel of your case.
- Locate an available PCIe slot (x1 is fine for most adapters).
- Remove the corresponding slot cover on the case.
- Insert the WiFi adapter firmly into the slot until it clicks.
- Screw the adapter bracket to the case.
- Attach the antennas to the rear connectors.
- Close the case and reconnect power.
- Boot into Windows and install the driver.
- Connect to your wireless network.
After installation, you should see the new adapter in Device Manager and in your network settings. A PCIe card generally delivers better performance and stability than a USB dongle, especially for gaming.
Step-by-Step: Using a USB WiFi Dongle
If you do not want to open your case or you lack a spare PCIe slot, a USB WiFi dongle is the simplest solution. Modern dongles are small, affordable, and support WiFi 5 or WiFi 6.
Installation Steps
- Plug the USB dongle into an available USB port (preferably USB 3.0).
- Wait for Windows to detect the device.
- Install the driver if Windows does not do it automatically.
- Open network settings and connect to your WiFi network.
- Position the dongle for best signal; use a USB extension cable if needed.
USB dongles are convenient but can be more susceptible to interference and usually offer lower peak speeds and weaker antennas than PCIe cards. For a desktop gaming rig, a PCIe adapter is generally the better long-term choice.
Ethernet vs WiFi on the B450 Tomahawk
Since the Tomahawk B450 includes Gigabit Ethernet, you should consider whether you even need WiFi. For many users, a wired connection is superior.
- Latency: Ethernet offers lower and more consistent ping, which matters for competitive gaming.
- Speed: Gigabit Ethernet can sustain higher real-world throughput than many WiFi setups.
- Stability: Wired connections are not affected by walls, interference, or distance.
- Convenience: WiFi wins when the router is far away or when you cannot run a cable.
If your router is in the same room or you can route a cable, Ethernet is the best option on this board. If not, add a quality wireless adapter.
