AI Ready!

The IW-RG650A 6.5U GPU server is specially designed for AI and HPC applications, featuring a spacious, independent GPU chamber that supports multiple high-end GPU installations, allowing you to build efficient AI models with reasonable hardware computation costs.

Dual Chamber Layout

The IW-RG650A features a 6.5U dual-chamber design, with a 4.5U chamber for GPUs and a 2U chamber for system components, enhancing scalability, streamlining the assembly process, and facilitating future maintenance.

4.5U chamber for GPU
2U chamber for MB, CPU cooler and system components

Full-height PCIe slots x 18

Low-profile PCIe slots x 7

Riser cables included

Fully Supported

A total of 18 full-height full-length PCIe slots on the top chamber are designed for high-end GPU installations, with 4 PCIe Gen4 riser cables included. For configurations requiring more than four GPUs, additional riser cables are available as optional accessories. 7 half-height full-length PCIe slots on the bottom chamber for optional half-height expansion cards configurations or future upgrades.

Independent Heat Dissipation

Thanks to the dual-chamber design, dedicated airflow tunnels are provided for GPUs and system components, allowing independent heat dissipation. This enhances cooling efficiency, prevents heat interference, and ensures stable system performance.

Fan hub

Hot-swap fan

Keep It Cool

A total of 9 hot-swappable 80x38mm 12,000 RPM PWM fans are pre-installed for exceptional cooling – 6 for the GPUs and 3 for the system components. An included fan hub enhances cable management and prevents cable clutter.

Storages Support

Total of 2 tool-less SSD brackets (1 included) can be installed for storage needs, each SSD tray can install up to 2 SSDs (one SATA cable is included; additional cables are available as optional accessories.).
