KHACHIMO FSP400-60DL 48V 400W ATX Power Supply

48 V ATX supply for low-noise builds

This 400 W unit delivers power from a 48 V DC source using an ATX form factor. It targets system integrators and enthusiasts building compact or industrial PCs that run from a 48 V bus and value certified efficiency. The 80 PLUS Gold rating confirms high conversion efficiency across typical loads. Modern Standby compatibility ensures rapid wake times for always-ready desktops.

Sustained output with resonant LLC and DC-to-DC

Resonant LLC topology paired with DC-to-DC conversion maintains tight voltage regulation during prolonged workloads. The design minimises ripple and suppresses coil whine even when the supply runs continuously at significant load. Gold-level efficiency reduces waste heat, allowing the fan to remain idle longer under real-world conditions. Stable output is preserved without the voltage drift seen in simpler topologies.

Semi-passive cooling and standard ATX mounting

Zero RPM fan mode stops the fan completely at low and medium loads, yielding near-silent operation for office or media-centre use. The ATX chassis fits standard mounting points in typical cases and racks. DC-to-DC architecture contributes to cleaner power delivery and quieter electrical performance day to day. Builders relying on a 48 V infrastructure gain a reliable, standards-compliant power solution.
