Plugable Thunderbolt 5 AI eGPU Enclosure (TBT5-AI)
Overview
The Plugable TBT5-AI is a Thunderbolt 5 external GPU enclosure purpose-built for AI/ML workloads, gaming, and content creation. Featuring an integrated 850W ATX 3.1 power supply with 80 Plus Gold certification and a PCIe x16 slot (electrical PCIe 4.0 x4) supporting full-length, 3-slot desktop GPUs up to 346mm, it transforms compatible laptops, mini PCs, and handheld gaming PCs into high-performance workstations. With dual Thunderbolt 5 ports (80Gbps, 96W PD upstream), a USB-C 3.2 Gen 2 port, and TAA compliance, it is equally suited for local AI inference, LLM development, high-fidelity gaming, and professional creative workflows. The tool-less chassis design and smart fan cooling ensure easy GPU swaps and reliable sustained performance. Note: GPU is not included; M-series Mac devices do not support external GPUs.
Key Highlights
-
Thunderbolt 5 eGPU enclosure with built-in 850W ATX 3.1 power supply (80 Plus Gold) — delivers up to 80Gbps bandwidth (PCIe 4.0 x4) for near-native desktop GPU performance on Thunderbolt 5, Thunderbolt 4, and USB4 laptops, mini PCs, and handheld gaming PCs
-
PCIe x16 slot supports full-size desktop graphics cards up to 3 slots wide and 346mm long — compatible with NVIDIA GeForce RTX 40/50-series and AMD Radeon RX 7000/9000-series GPUs for gaming, AI/ML, and creative workloads
-
Designed for local AI inference and development — 850W PSU supports power-hungry workstation and AI accelerators; TAA compliant for government, education, and enterprise procurement
-
96W Power Delivery via Thunderbolt 5 upstream port to charge connected laptops and handhelds during use — single-cable data, display, and power for compatible devices with a second Thunderbolt 5 downstream port for daisy-chaining
-
Tool-less slide-off panel design for easy GPU installation and swapping; active cooling system with smart fan control for sustained thermal performance under load
