Model AX900 Bluetooth 5.4

  • Faster wireless speeds with Wi-Fi 6 up to 900 Mbps
  • Reliable Bluetooth 5.4 connections for peripherals and low-energy devices
  • Dual-band 2.4 GHz and 5.8 GHz flexibility for less interference
  • Fits PCIe x1, x4, x8 or x16 slots on desktop motherboards
  • Built-in heatsink keeps performance stable during heavy use

Desktop Wi-Fi 6 upgrade

The fenvi AX900 adds Wi-Fi 6 and Bluetooth 5.4 to a desktop PC through any PCIe x1, x4, x8 or x16 slot. It delivers dual-band wireless with a combined rate of 900 Mbps, reaching 286 Mbps on 2.4 GHz and 600 Mbps on 5.8 GHz. A red heatsink helps maintain stable operation during continuous use.

Windows 10 or 11 desktops only

This adapter suits builders adding modern wireless to a Windows 10 or 11 64-bit system with a free PCIe slot. It does not suit buyers who need macOS or Linux support, nor those who require an internal M.2 or USB form factor instead of a full-size card.

Wi-Fi 6 with Bluetooth 5.4 on PCIe

The single deciding specification is the combination of Wi-Fi 6 (802.11ax) and Bluetooth 5.4 on a standard PCIe interface. If your desktop runs Windows 10 or 11 64-bit and has an open PCIe slot, this card provides both wireless standards in one package.

Questions about this item

Will the external antennas on the fenvi AX900 need periodic replacement?

The external antennas are detachable and can be swapped if damaged, but no scheduled replacement is required under normal use.

What limits sustained throughput on the AX900 during long transfers?

The PCIe 1x lane caps real-world speed below the 900 Mbps PHY rate, and the AIC8800M80 chipset manages thermal throttling via the heatsink.

How much heat and noise does the fenvi AX900 produce when running all day?

The passive heatsink keeps the AIC8800M80 chipset cool without a fan, so the card adds no audible noise and minimal heat to the case.
