Modder adds Radeon RX 9070 XT eGPU to Steam Machine, runs Crimson Desert at over 100 FPS on High — moves boot drive to USB-C port, leverages M.2 to OCuLink adaptor and eGPU dock
A Redditor has successfully connected a very powerful eGPU the Steam Machine via an M.2 to OCuLink adapter.
A Redditor successfully connected an AMD Radeon RX 9070 XT eGPU to Valve's compact Steam Machine. The process involved fitting an M.2 to OCuLink adapter to host the powerful graphics card, which was then connected to an Aoostar EG01 eGPU dock. The main challenge was adapting the boot drive due to the Steam Machine's limited M.2 PCIe 4.0 NVMe slot, which the original system uses for its SSD.
Large_Customer_3840 solved this issue by moving the boot drive into a USB-C to NVMe caddy and booting from there. The Steam Machine's USB 3.2 Gen 2 (10 Gbps) port was utilized for the operating system, as it is the fastest port available on the device. The eGPU dock, while functional, is a bit messy due to its exposed cables and lack of an enclosure.
Despite this, the Redditor was pleased with the results, as the AMD Radeon RX 9070 XT eGPU allowed them to run Crimson Desert at over 100 frames per second on High settings.
