Dell 2400W Single Hot-Plug Power Supply for PowerEdge

The Dell 2400W power supply is the maximum-wattage hot-plug PSU for PowerEdge servers exceeding 1400W total system power.

Dell 2400W Power Supply — Hot-Plug for High-Power Server Builds

A server with dual high-TDP Xeons, multiple A100/H100 GPUs, NVMe and high-speed networking can sustain 1800–2200W under full load. The 2400W output provides a margin above this, preventing operation at or near the PSU’s rated maximum. Running a PSU near its rated limit reduces efficiency and longevity. The hot-plug form factor allows PSU replacement without server shutdown on supported single-PSU chassis. Dell certification ensures compatibility with PowerEdge models supporting this wattage.

When a 2400W PSU is Necessary in South African AI and HPC Servers

South African data centres building AI, HPC or GPU virtualisation servers should calculate total system power before selecting a PSU. An NVIDIA H100 SXM5 draws 700W TDP; an A100 PCIe draws 300–400W. Two A100 PCIe GPUs plus dual high-TDP Xeon processors can push total server power to 1600–1800W under full load. The 2400W supply provides appropriate headroom. Under-provisioning a PSU in a GPU-dense server causes throttling, instability or shutdown under sustained load. Browse server power supplies in the Components section at Briggi Tech.

Redundant Configuration

This is a single non-redundant (1+0) hot-plug supply. For production environments where PSU failure must not cause downtime, a second 2400W PSU should be installed for a redundant (1+1) configuration, where each PSU carries half the load and provides automatic failover. The R750xs, R760 and compatible platforms support dual 2400W PSUs.

The 2400W supply is also used in configurations where a single PSU must power a large NVMe storage backplane alongside dual processors and networking cards, even without GPU accelerators. Always calculate total system power using Dell’s Power Calculator tool before selecting a PSU wattage for a given configuration.
