KHACHIMO 550W Power Supply DPS-550AB-54A

550 W ATX Power Supply for Modern Standby Systems

The KHACHIMO DPS-550AB-54A is a 550 W ATX unit built for PCs that use Modern Standby sleep states. It delivers reliable power for mainstream desktop builds and workstations that prioritise fast wake times and efficient low-load operation. This supply suits users who want quiet, efficient performance without over-provisioning wattage.

Sustained Load Behaviour with Zero RPM Fan Mode

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery while reducing coil whine. The 80 PLUS Gold certification ensures high efficiency across the load range, keeping temperatures lower and acoustic output minimal. At low and medium loads the fan stops completely, providing near-silent operation during typical desktop workloads.

Replaces Older ATX Units Lacking Modern Standby

This unit upgrades systems that currently use standard ATX supplies without Modern Standby compatibility or Gold-level efficiency. The jump is worthwhile when faster wake-from-sleep, lower idle power draw and fanless operation at moderate loads are required. It does not address builds needing higher wattage headroom or redundant power configurations.
