KHACHIMO ADVANTECH 500W ATX PSU

The KHACHIMO ADVANTECH FSP500-40MRB is a new 500W ATX power supply built with Resonant LLC topology and DC-to-DC conversion. It carries 80 PLUS Gold certification for high efficiency, lower consumption and reduced heat. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suits modern standby builds; not for higher output

This unit suits builders who want a Gold-efficiency 500W ATX supply with Modern Standby compatibility and a quiet Zero RPM fan mode. It fits systems that benefit from Resonant LLC topology and DC-to-DC conversion for clean power and lower coil whine. Builders whose configurations demand more than 500W of continuous power should look at higher-output units instead.

500W ATX with 80 PLUS Gold

The single specification that decides fit is the 500W ATX rating combined with 80 PLUS Gold efficiency. This defines the maximum continuous power the supply can deliver and the efficiency level it meets across typical loads. Verify that your system's total power draw stays within this 500W limit before purchasing.

Questions about this item

What does the 500 W rating mean once the unit is installed in a PC?

It means the supply can continuously deliver up to 500 W of combined DC power to the motherboard, graphics card, drives and peripherals under normal operating temperatures.

What does the 80 PLUS Gold certification cap in practice?

It certifies that the unit meets Gold-tier efficiency thresholds at the standard test loads, so less input power is wasted as heat and the fan can remain idle more often.

What does the ATX form factor require for physical mounting?

The unit fits a standard ATX power-supply bay and uses the regular four-screw mounting pattern found on most desktop chassis.
