My legion go with oculink egpu
I absolutely love it. I was getting frustrated with Thunderbolt eGPU performance and was seriously considering building a desktop PC. Then I came across the OCuLink mod and decided to give it a try. It ended up costing much less than building a PC while giving me almost exactly what I wanted.
The Thunderbolt enclosure does block one of the vents, but temperatures are still excellent—around 85°C under maximum load in Performance mode. It’s paired with an RTX 5080, so I get the best of both worlds: a portable handheld when I’m on the go and desktop-class gaming when I’m at my desk.
I also completed the 80Wh battery mod and use an angled Thunderbolt adapter for charging.
What I used:
80Wh battery upgrade
Custom 3D-printed back cover (Amazon)
GRAUGEAR Thunderbolt 4 NVMe enclosure (Amazon)
M.2 2280 adapter
PCIe 5.0 M.2 eGPU adapter
That’s it!
It’s actually a very straightforward mod. The only hardware you need is:
An OCuLink eGPU dock
A USB4 NVMe enclosure
An M.2 2280 adapter
A custom 3D-printed rear cover that exposes the M.2 connector easily available on Amazon.
First, move your internal SSD into the USB4 enclosure and boot from it to make sure everything works. In some cases, you may need to run a small registry (.reg) file once while booted from the internal SSD before moving it, but that’s a one-time step.
After that, connect the OCuLink eGPU adapter to the M.2 slot and you’re done. Mine is not oculink but direct m.2 but works same for oculink like aostar ago2 or minisforum deg1.
Some double side tape to stick the usb4 enclosure.
It’s much simpler than it sounds, and once it’s set up, it works really well.
