What Is Power Distribution Unit (PDU)?_
A PDU distributes electrical power from a facility circuit to the equipment within a rack. Data center PDUs come in basic (power strip), metered (with monitoring), monitored (per-outlet metering), and switched (remote outlet control) variants. GPU racks typically require high-amperage PDUs supporting 3-phase power at 208V or 415V, with dual-feed redundancy.
Technical Details
PDU selection for GPU racks depends on total rack power draw, outlet configuration, and monitoring requirements. An H100 rack at 40–80 kW typically uses dual high-amperage PDUs with C19/C20 outlets for server power connections and C13/C14 outlets for switches and accessories. For GB200/GB300 NVL72 racks at 120 kW, power delivery may use 415V 3-phase with dedicated circuit breakers and high-gauge power whips. PDU types progress in capability: basic (power distribution only), metered (total load monitoring), monitored (per-outlet current/voltage monitoring), and switched (remote on/off control per outlet). Intelligent PDUs with network connectivity enable remote monitoring of power consumption, environmental conditions, and outlet status.
How Leviathan Systems Works with Power Distribution Unit (PDU)
Leviathan Systems mounts and wires PDUs as part of GPU rack assembly, selecting appropriate configurations for the power density and monitoring requirements of each deployment.
