Overview Specifications

01 / OVERVIEW

Product overview

The OCG4660-4H12-C is a robust and scalable 4U rackmount GPU server chassis purpose-built for high-performance computing, storage, and GPU-intensive applications. Constructed from 1.0mm Taiwan SGCC steel, it offers durability and rigidity for demanding data center environments.

With support for up to 12 × front-access 3.5″ hot-swappable hard drive bays (compatible with 2.5″) and 2 × internal 3.5″/2.5″ drive modules, this chassis ensures flexible storage expansion. The system accommodates 11 × full-height PCIe slots and is specially designed for Intel X11DPG-QT and X12DPG-QT motherboards, guaranteeing compatibility with dual-socket platforms.

Designed to handle heavy GPU loads, the chassis supports up to 4 gaming-grade GPU cards (335mm max length), making it ideal for AI, deep learning, and rendering tasks. Advanced thermal performance is delivered via 4 × 9238 hot-swappable system fans and rear support for up to 4 × 8038 fans (2 internal + 2 external optional).

The power subsystem supports redundant 80PLUS Platinum CRPS power supplies, scaling up to 3200W, ensuring uninterrupted performance for power-hungry configurations.

With its fully customizable front panel, cable options, branding, and support for U.2 NVMe and SAS/SATA hybrid backplanes, the OCG4660-4H12-C is a flexible platform for OEM/ODM projects and enterprise deployment.
