AOOSTAR AG03 eGPU Docking Station with 800W Built-in PSU, OCuLink & Dual Thunderbolt 5 (80Gbps) External GPU Dock, Supports Up to 500W GPUs, PCIe 4.0 x4, 140W PD for Thunderbolt 4/5 USB4 Windows 11

Why it's a great deal

• 【Dual Thunderbolt 5 & OCuLink High-Speed eGPU Expansion】Upgrade your laptop, mini PC, or workstation with the AOOSTAR AG03 external GPU dock featuring 1× OCuLink port and 2× Thunderbolt 5 ports. OCuLink provides up to 64Gbps bandwidth, while Thunderbolt 5 delivers up to 80Gbps bidirectional bandwidth (up to 120Gbps bandwidth boost for video applications), enabling high-performance GPU expansion and next-generation 8K display setups.

• 【Built-in 800W Server-Grade Power Supply for High-End GPUs】The AG03 eGPU docking station features an integrated 800W server-grade PSU, eliminating bulky external power adapters or additional ATX/SFX power supplies. Dedicated 500W GPU power output supports high-performance graphics cards such as NVIDIA RTX 4090 and AMD RX 7900 XTX, with additional power headroom for stable operation, lower fan noise, and reliable voltage performance. (GPU not included.)

• 【140W PD Fast Charging & Direct DisplayPort 2.1 GPU Output】Connect through the primary Thunderbolt 5 port to enjoy up to 140W PD 3.1 reverse charging for compatible laptops, helping power demanding devices during intensive workloads. The dedicated DisplayPort 2.1 output delivers video directly from your installed GPU, supporting high-resolution displays up to 8K with reduced system overhead compared with traditional USB4 docking solutions.

• 【PCIe 4.0 x4 Performance & Wide GPU Compatibility】Designed for desktop-class graphics performance, the AG03 supports standard NVIDIA, AMD, and Intel GPUs through a PCIe 4.0 x4 interface with reinforced metal shielding for improved signal stability. Compatible with devices featuring OCuLink or Thunderbolt connectivity, including Windows laptops, gaming handhelds, Mini PCs, and professional workstations.

• 【Compact Aluminum Open-Frame Design with Quiet Cooling】Built with a premium aluminum alloy frame, the AG03 measures only 22.5 × 11 × 6 cm and weighs approximately 1.5kg. The open-frame design supports various GPU sizes without length limitations while maximizing airflow and heat dissipation. Dual signal amplifiers help maintain stable connections, while optimized cooling keeps operating noise around 41–45dB under heavy load.

• 【Important Compatibility Notes Before Purchase】Please confirm device compatibility before ordering. 1.OCuLink does not support hot-plugging. Always power off the dock before connecting or disconnecting the OCuLink cable. 2.The built-in 800W PSU powers the eGPU dock only; graphics card is not included. 3.Lenovo TGX hot-swap is only supported on compatible TGX-enabled devices. 4.Not compatible with certain devices including AOOSTAR GT37/WTR MAX, ROG Xbox Z2 Extreme, RX 9070 XT GPU setups, and some Mini PC models. Please verify your device interface and compatibility before purchase.
