Kosin decides to utilize this modification on one of their laptops, the laptop utilized in this unique setup is the Air 14. This laptop utilizes the Ryzen 4600U processor, which also features an M.2 slot. This video showcases how Kosin modified this laptop to connect the RTX 3090 for data transfer and power the RTX 3090 using the laptop’s power supply.
The modder removed the installed M.2 SSD and then connected an M.2 adapter to PCIe Slot; this allows the RTX 3090 to connect to the laptop. This adapter cannot power the new external graphics card, and this setback required the modder to drill a slot into the laptop’s housing. This hole drilled in the housing allows the power cord to be moved out from the laptop’s internal.

After connecting the RTX 3090 graphics card through the power cord and the M.2 adapter, The laptop does boot and can be stressed tested. The video released by Kosin stressed tested this graphics card through 3D Mark Time Spy. This stress test showcases a score of 14,008 points, which does show a small drop in performance as when the RTX 3090 was paired with an Intel Core i9-900K processor, features a Time Spy score of 15,000 Points. While this 1,000 point drop in performance may seem like a significant drop, the gaming performance will be significantly better than utilizing the graphics cores on the Ryzen 4600U. This drop could potentially be because the M.2 slot only has four PCIe lanes, which are less than most PCIe slots provided by motherboards.
