BFKK AG02 EGPU Dock 800W PSU OCuLink USB4 TGX

SKU CH-W4ZH-KWJCG

An external GPU dock with an 800 W power supply delivering up to 600 W to the card via OCuLink and USB4

  • Compatible with most external graphics boards via OCuLink and USB4
  • 64 Gbps PCIe 4.0 x4 bandwidth through OCuLink interface
  • 800 W PSU powers dock and supports GPUs up to 600 W
  • TGX hot-swap on supported 2024 Lenovo ThinkBook 14+ and 16+ models
  • Works with Windows 11 22H2+ and macOS over AC 220 V input

Interface Requirements

The BFKK AG02 eGPU dock delivers 800 W of power and connects through a single OCuLink plus USB4 interface. It accepts graphics cards drawing up to 600 W and provides three 8-pin power connectors. The unit operates on 220 V AC input and supports both Mac and Windows 11 22H2 or later. A TGX hot-swap mechanism is available on compatible 2024 Lenovo ThinkBook 14+ and 16+ models.

Who It Suits

Builders with a laptop or mini PC that already exposes an OCuLink port can add desktop-class graphics without opening the chassis. The dock is not for buyers who want more storage, extra USB ports, or a second card slot. It also does not suit users whose only high-speed connection is a standard USB-C socket, because the OCuLink link is mandatory. Legion Go and Xbox Ally X owners should look elsewhere, as those devices are explicitly excluded.

Deciding Specification

The single specification that decides fitment is the presence of an OCuLink port on the host system. Without it the enclosure cannot be used, regardless of other USB-C sockets the computer may offer. The dock supplies 64 Gbps effective bandwidth over PCIe 4.0 x4 lanes through that OCuLink connection, and the interface uses a locking connector that must be released before unplugging.
