What Is GPU Rack?_
A GPU rack is a standardized enclosure (typically 42U or 48U) that houses GPU servers, network switches, power distribution units, and cable management hardware. In AI data centers, GPU racks draw 40–120+ kW per rack, which is 4–12x the power density of traditional server racks, requiring specialized power distribution, cooling, and structural support.
Technical Details
GPU racks differ from traditional server racks in almost every dimension. Power density is the most obvious change: where a conventional rack draws 5–15 kW, a rack of H100 nodes can draw 40–80 kW, and a GB200 or GB300 NVL72 rack draws approximately 120 kW. This cascading density affects PDU sizing (high-amperage 3-phase at 208V or 415V), cable gauge and routing (heavier power whips, more data cables), structural requirements (floor loading verification for racks exceeding 1,300 kg), and cooling infrastructure (transition from air to mandatory liquid cooling at Blackwell densities). Rack design must also accommodate cable management for thousands of connections per row, including fiber, copper, and liquid cooling lines in organized pathways.
