Knowing how many USB ports your motherboard supports is key for connecting peripherals like:

Why does USB port count matter?

  • Keyboards, mice
  • External drives
  • Webcams, microphones
  • Game controllers

Too few ports may require USB hubs or upgrades.

Types of USB ports on a motherboard

External (rear I/O panel)

  • USB 2.0, 3.0, 3.1 Gen1/Gen2, USB-C
  • Usually 4 to 8 ports, depending on model

Internal headers (for front panel ports)

  • USB 2.0 header: supports 2 ports
  • USB 3.x header: supports 1 or 2 ports
  • USB-C internal header (on newer boards)

How to check how many USB ports you have

1. Check your motherboard model

  • Look on the board itself (printed model)
  • Or use software like CPU-Z or Speccy

2. Visit the official specs page

Search your model online and check the manufacturer’s specs sheet. Look under “rear I/O ports” and “internal connectors.”

3. Use Device Manager (Windows)

  • Open Device Manager
  • Go to “Universal Serial Bus controllers”
  • This shows USB controllers, but not always number of ports

Example

MSI B550 Tomahawk:

  • Rear: 6 USB ports (2x 2.0, 2x 3.2 Gen1, 2x 3.2 Gen2)
  • Internal headers: 2 USB 2.0 (for 4 ports), 1 USB 3.2 Gen1 (for 2 ports)
  • Total possible: 12 USB ports

FAQs

Can I add more USB ports?
Yes. Use a PCIe USB expansion card or a powered USB hub.

Is USB 3.2 faster than 2.0?
Yes. USB 3.2 Gen2 can reach up to 10 Gbps vs. 480 Mbps for USB 2.0.

Are front panel USBs part of the motherboard?
They’re connected via internal headers but not pre-installed.

Conclusion

Your motherboard can support many USB ports via rear and internal headers. Checking your model’s specs is the best way to know how many are usable for your needs.
