Graviton 9655 Wi-Fi 6 Bluetooth 5.2 PCIe Adapter

SKU CH-45BR-RD7ED MPN 9655

Adds WiFi 6 and Bluetooth 5.2 to a desktop via a PCIe x1 slot, delivering dual-band 2.4 GHz and 5.8 GHz wireless with speeds up to 1800 Mbps

  • Wi-Fi 6 reaches 1800 Mbps total throughput across both bands
  • Bluetooth 5.2 connects peripherals without a separate dongle
  • Dual-band 2.4 GHz and 5.8 GHz operation avoids congested channels
  • PCIe x1 interface fits x4, x8 and x16 slots
  • Windows 10 and 11 64-bit support for immediate driver installation

What this adapter adds

The Graviton 9655 is a PCIe x1 wireless network card that brings WiFi 6 and Bluetooth 5.2 to a desktop PC. It targets builders who need dual-band 2.4 and 5.8 GHz connectivity without using a USB port. The card fits any standard PCIe slot, including x4, x8 and x16, and supports 64-bit Windows 10 and 11.

Build and daily use

A metal shield surrounds the main board to improve heat dissipation during sustained high-speed transfers. Two external antennas screw onto the bracket for adjustable positioning and better reception through walls. The Bluetooth 5.2 controller lets you pair keyboards, mice, headsets or game controllers directly inside the case.

The deciding spec

Maximum link rates are 574 Mbps on the 2.4 GHz band and 1200 Mbps on the 5.8 GHz band, combining to the advertised 1800 Mbps figure. The radio uses 160 MHz channel width on 5 GHz, which is wider than the older 80 MHz standard. Buyers whose router only supports 80 MHz channels will not reach the top throughput.

Questions about this item

Does the PCIe x1 interface on the Graviton 9655 cap WiFi 6 throughput below the 1800 Mbps rating?

The card uses a PCIe x1 link that is also compatible with x4, x8 and x16 slots. That interface provides enough bandwidth for the 1200 Mbps 5.8 GHz stream and the 574 Mbps 2.4 GHz stream that make up the 1800 Mbps total.

What slot and bracket space does the 9655 need inside a desktop case?

It fits any standard PCIe x1, x4, x8 or x16 slot and occupies one full-height expansion bracket at the rear of the chassis.

Which step do builders often miss when installing the 9655 on Windows 10 or 11 64-bit?

After seating the card, many forget to install the Bluetooth 5.2 driver separately from the WiFi 6 driver; both are required for the adapter to appear in Device Manager.
