2026 Global Hot-swappable Power Supply Unit (Hot-swap PSU) Market Annual Research Report

I. Definition

A Hot-swappable Power Supply Unit (Hot-swap PSU) is a modular power supply system widely deployed in servers, data centers, and other high-availability computing environments. It enables live insertion and removal of power modules without shutting down the system, ensuring uninterrupted operation.

Hot-swap PSUs are typically designed within redundant power architectures such as N+1 or 1+1 configurations, enabling continuous system uptime even during maintenance or power module failure. This significantly reduces downtime risk and enhances operational resilience.

These systems are extensively used in enterprise servers, storage infrastructure, and networking equipment, forming a critical component of modern data center power architectures.
