This Cybertruck excels not on the road, but in gaming. A YouTuber connected a desktop NVIDIA RTX 4090 graphics card to it, which is comparable in size to the PC itself, in a rather extravagant manner.
This idea may seem amusing, but the modification is indeed real, albeit with some additional issues that need addressing. The primary challenge for the PC is the lack of an easily accessible M.2 slot for PCIe bus access. Additionally, the Cybertruck's PC is relatively difficult to disassemble.
The enthusiast decided to test a PCIe adapter using the M.2 Wi-Fi slot, which is relatively easy to access. This slot is limited to only two lanes (32 Gbps), making it slower than Thunderbolt 4 (40 Gbps) and OCuLink (PCIe 4.0×4, 64 Gbps).
The results showed that the M.2 bandwidth does not allow the graphics card to operate at full capacity. The RTX 4090, with a TDP of 450 W, only drew 60 W in most tests and performed below that of integrated graphics like the AMD Radeon 780M.
Ultimately, the chassis of the Cybertruck had to be removed—a task the modder was reluctant to undertake—in order to connect OCuLink to the M.2 socket on the motherboard itself. This setup may not look as impressive as in the photos, but it allows the graphics card to utilize 400 W of power and deliver adequate performance. OCuLink adapters over M.2 seem intriguing, but finding a spot for them in laptops or mini-PCs proves challenging. This Cybertruck uses a repurposed laptop motherboard.
