EXP GDC OCuP4 GaN - OCuLink External GPU Dock (OCuP4GaN V2)

The OCuP4 GaN is a compact OCuLink eGPU dock for laptops and small PCs that need desktop-class graphics without a full tower. Built around PCIe 4.0 x4 with ReDriver signal enhancement, it keeps the external GPU link stable while you game, edit, or run GPU apps.

Power built for real cards

1. GaN or laptop-style PSU via Dell 7.4 x 5.0 or Lenovo square plug
2. Dock power diagram: Max 400W
3. GPU output: 400W (20V) rating; ~360W continuous GPU power (measured with a 400W GaN supply)
4. Included cables: dual 8-pin (breakaway to 6-pin) + 16-pin (12VHPWR)
5. Page guidance: keep GPU max load 360W for system stability

Choose the right PSU for your card

The product page lists recommended supply wattage by GPU tier (with or without PD use)for example entry cards around 90170W class, mid cards 230300W class, and high-end cards such as RTX 3080 / 4080 / 5080 and RX 6800XT / 7800XT class at 400W. Always match the official table for your exact card. Page notes: normal gaming use is fine; benchmark stress runs are not recommendedfull load may trip dock protection (unplug the PSU adapter to recover). Monitor real-time GPU power with GPU-Z or AIDA64 and downclock if needed.

Host & cooling

1. Host interfaces: OCuLink / TGX / M.2 M-Key
2. Dual-fan, dual-path airflow cools the dock and GPU backplate
3. Power-on/off sync with your PC; one-key start switch on the dock
4. Portable / desktop use; optional metal case
