275W ATX Power Supply

The KHACHIMO FSP275-60CU is a 275W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high-efficiency operation and supports Modern Standby for rapid wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power across all rails.

Suitable for compact builds

This unit suits builders who want low-load efficiency, near-silent operation via Zero RPM fan mode, and support for modern sleep states. It is not intended for systems requiring higher wattage output, multiple high-power GPU connectors, or server-grade redundancy features.

Sustained load behaviour

Under continuous load the resonant LLC design maintains stable voltage regulation while the cooling fan remains off until medium loads are reached. This approach reduces coil whine and keeps temperatures lower during extended use compared to designs without DC-to-DC conversion.

Questions about this item

Does this 275W ATX supply need a separate 80 PLUS Gold certified motherboard to deliver its rated efficiency?

The 80 PLUS Gold certification belongs to the power supply itself; it only requires a standard ATX motherboard to operate at its rated efficiency.

Will the Zero RPM Fan Mode still activate when paired with an older motherboard that lacks Modern Standby support?

Yes, Zero RPM Fan Mode depends on load level, not on Modern Standby, so the fan can still stop at low and medium loads with an older board.

How can I confirm the Resonant LLC topology with DC-to-DC conversion is functioning after installation?

You will observe stable voltages under load, minimal coil whine, and the fan remaining off during light use, indicating the topology is working as designed.
