KHACHIMO M310 M410 M510 M610 10Pin 450W Power Supply

Purpose-built for Dell desktops

This 450 W ATX power supply is designed as a direct replacement for Dell OptiPlex and Precision models that use a 10-pin main power connector. It matches the FSP450-20TGBAB, DPS-450AB-71 and related Dell part numbers so the unit fits the proprietary wiring without adapters. System integrators and IT teams can swap the unit in minutes and restore reliable power to compact business PCs.

Upgrade from failing or noisy OEM units

The supply replaces ageing 310 W, 410 W, 510 W or 610 W Dell bricks that have developed coil whine, fan rattle or voltage sag under load. Modern Standby compatibility and Zero RPM fan mode mean the new unit idles silently and wakes instantly, a noticeable improvement over older designs that lack low-load efficiency. The jump is worth it when the original unit shows instability or when a quieter office environment is required.

Limits of the 10-pin Dell interface

The proprietary 10-pin connector prevents use in standard ATX motherboards and limits the supply to Dell chassis that accept the 20TGBAA or PCH015 form factor. Cable routing is fixed, so builders who need modular cables or non-Dell pinouts cannot use this unit. Efficiency peaks at 80 PLUS Gold levels, but the fixed pin layout and 450 W ceiling restrict future GPU upgrades that demand auxiliary power connectors.
