500W ATX power supply for modern PCs

The KHACHIMO FSP500-40MRB delivers 500 watts of continuous power in a standard ATX form factor. It targets builders assembling mainstream desktops or workstations that require reliable energy delivery and support for Modern Standby sleep states. The 80 PLUS Gold certification confirms high efficiency across typical load ranges.

Capacity headroom for mid-range builds

At 500 watts the unit comfortably powers a modern CPU paired with a mid-range graphics card, storage drives and peripherals. Headroom remains for moderate overclocking or future component upgrades within the same power envelope. Systems demanding sustained loads above 500 watts will exceed the rated output and require a higher-capacity supply.

Quiet thermals with Gold efficiency

80 PLUS Gold efficiency reduces waste heat, allowing lower internal temperatures and less fan activity under normal workloads. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further minimises coil whine and supports energy-efficient sleep states.

Perguntas sobre este artigo

Will the 500W ATX unit fit and power an older system that still uses a standard 24-pin motherboard connector?

Yes, the ATX form factor and 500W rating are designed for standard desktop builds including older motherboards with a 24-pin power socket.

How can I confirm the Zero RPM Fan Mode is active once the PC is running?

Under light or medium workloads the cooling fan should stay completely still, giving near-silent operation you can verify by listening at the rear grille.

What accessories are bundled with the FSP500-40MRB power supply in the retail package?

The box contains the power supply unit itself and the AC power cord; all modular cables required for your build are attached or included in the package.
