How we scored them
The Office Score weighs performance (computer count, data speed, video resolution and power delivery), build, value, safety and warranty. For a KVM switch, safety means stated specifications like FCC or CE and the materials of the housing. Only the DXchip states a warranty term, with 1 year. How we pick explains the weights.

How to choose the best kvm switch with usb c
How many computers will you switch?
Three of the five handle 2 computers: the DXchip, the Cable Matters 201352 and the Alxum. The Cable Matters 201343 handles 3 computers, the most here. The BENFEI also handles 2 computers but only for USB devices, with no video. Count your machines before choosing, because a 2-port switch cannot grow to a third computer later. See best kvm switch for 2 computers for more two-machine options.
20Gbps or 10Gbps data speed
The Alxum and both Cable Matters switches list 20Gbps, which suits large file transfers and high-resolution video. The DXchip lists 10Gbps on its 4 USB 3.1 Gen2 ports, which is fine for keyboards, mice, printers and everyday drives. The BENFEI lists 5Gbps on USB 3.0. Faster is not always necessary; match the speed to what you actually move across the switch.
| Switch | Speed | Computers |
|---|---|---|
| Cable Matters 201343 | 20Gbps | 3 |
| Alxum | 20Gbps | 2 |
| DXchip | 10Gbps | 2 |
| BENFEI | 5Gbps | 2 |
Video resolution and the macOS limit
The 20Gbps switches list 8K at 30Hz or 4K at 144Hz on Windows. On macOS, the Cable Matters switches list 4K at 60Hz, and the Alxum notes that macOS supports one 4K at 60Hz monitor. The DXchip lists dual 4K at 60Hz plus 1080P at 60Hz but notes that extended mode is not supported on Mac OS. If you use a Mac, confirm the monitor count the listing promises for macOS specifically.
Power delivery to the laptop
The Alxum and both Cable Matters switches list 140W Power Delivery pass-through to the active computer. The DXchip lists 100W Power Delivery, though the listing notes actual charging is 73 to 80W. The BENFEI has no power delivery; it is a USB data switch. Note that only the selected computer receives charging, not all connected machines at once.
Cables and dock compatibility
Several listings warn about cables. The Cable Matters switches require the included USB4 20Gbps cables and warn against Thunderbolt 3/4/5 cables or docks with built-in host cables. The Alxum notes that dock pigtails over 50CM may limit performance and does not support Dell docking stations. The DXchip asks for USB-C 3.1 Gen 2 cables within 1M. Use the cables the listing includes. See best usb hub with hdmi if you need a hub rather than a switch.
Setup Notes
- Check that each laptop USB-C port supports DisplayPort Alt Mode, as the listings require for video.
- Measure cable runs: the DXchip wants USB-C cables within 1M and HDMI/DP within 1.5M.
- For high-power devices, connect the extra power the BENFEI listing describes.
- Place the 5.91 by 3.94 by 1.97 inch DXchip where its vents have airflow.
- Keep the remote where you can reach it; the Alxum and Cable Matters 201343 include one.
