Introduction
—————————————————————
Today, we’re tearing down the HP DPS-1200FB A 1,200W server power supply, manufactured by Delta. Built in a standard 1U form factor, it uses a classic PFC, phase-shifted full-bridge, and synchronous rectification architecture, with hot-swap support and server-grade cooling. Inside, it features high-quality components from TI, Infineon, ST, onsemi, and major Japanese capacitor brands. Let’s open it up and see why this model became a benchmark for industrial server power supplies.
