  • description: In this video, I demonstrate how to build a Thunderbolt 4 eGPU dock using the EXP GDC TH3P4GAN GPU Dock and a 3D-printed case that is compatible with USB4 and supports 85W power delivery over Thunderbolt 3/4 for a laptop mini PC. 3D model files: https://www.printables.com/model/1230700-rtx-3050-ft-exp-gdc-th3p4gan-gpu-dock-and-a-3d-pri ITG Gear community: - Twitter: https://x.com/itggear - Patreon: https://patreon.com/ITGGear - Discord Server: https://discord.gg/A5WwMtREnk Items I used: - MSI RTX 3050 Low profile https://amzn.to/4i9RY3z - EXP GDC TH3P4GAN GPU Dock https://s.click.aliexpress.com/e/_oksUGfD - M3x5x5 Female threaded insert nut https://s.click.aliexpress.com/e/_oCtSwxD - M3x5x5 Screws https://s.click.aliexpress.com/e/_o2c5tuf Note: Please keep in mind that this eGPU setup is not budget-friendly and may not be worthwhile for everyone. I do not recommend buying every component solely for this build. However, if you already have most of the parts—like the GPU power supply—and you just need the Thunderbolt dock, then it's a great option to try. The laptop's CPU is a 10W Intel Core i7-10710U, and it is too slow to load games efficiently. The CPU creates a bottleneck during gaming. Since I currently don't have a PC compatible with a Thunderbolt port, I owe you a gameplay test on this GPU. I'll post another video showcasing the Thunderbolt eGPU setup's gaming performance, so stay tuned. 0:00 Introduction 0:29 Unboxing EXP GDC TH3P4GAN GPU Dock 3:25 Assembly 5:21 Finished project preview 6:19 Connection testing 7:17 eGPU stress test Description: Ever wondered how to upgrade your laptop's graphics performance without breaking the bank? In this video, I'll walk you through the step-by-step process of building your own Thunderbolt 4 eGPU.
