500W ATX power supply for Modern Standby PCs

This KHACHIMO FSP500-40MRA unit delivers 500 watts of continuous power in a standard ATX form factor. It is built for desktop systems that rely on Modern Standby for instant wake and efficient low-power states. The 80 PLUS Gold certification confirms high efficiency across typical load ranges.

Sustained load behaviour with Gold efficiency

Under continuous demand the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and ripple low. The 80 PLUS Gold rating means less waste heat during long sessions, so internal temperatures stay lower and the fan can remain idle longer. Zero RPM mode disengages the fan completely at low and medium loads for silent running.

Compatibility checks before ordering

Verify that your case accepts a standard ATX power supply and that your motherboard uses a 24-pin main connector plus the required CPU and GPU power leads. Confirm the system power draw fits within the 500 watt rating. This unit is not suited for builds needing higher wattage or non-ATX form factors.

Perguntas sobre este artigo

How quiet is the 500W FSP500-40MRA when the PC runs all day?

The 80 PLUS Gold efficiency and Zero RPM Fan Mode keep noise low; at light loads the fan stays off completely.

What cables or connectors must my build already provide for this PSU to work?

It uses a standard ATX form factor, so your case and motherboard need the matching ATX mounting holes and 24-pin power socket.

Will the FSP500-40MRA wake an older motherboard quickly from sleep?

Modern Standby compatibility and the resonant LLC topology with DC-to-DC conversion enable fast wake times and stable low-load power.
