500W ATX power supply

The KHACHIMO PWS-501P-1R is a new 500W ATX power supply built for modern desktop builds. It carries 80 PLUS Gold certification for high efficiency at typical loads. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power to components. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Suited to efficient mainstream builds

This unit suits builders who want Gold-rated efficiency and quiet operation in a standard ATX form factor. Zero RPM fan mode keeps the system near-silent at low and medium loads. Buyers who need higher wattage for multi-GPU configurations or extreme overclocking should look at a higher-capacity model instead.

Straightforward ATX installation

Installation follows the standard ATX mounting pattern and connector layout used by current cases and motherboards. The fan-stop feature engages automatically, so no software setup is required for silent running. Ensure the case provides adequate airflow for the power supply to exhaust heat under sustained heavy load.

Perguntas sobre este artigo

What motherboard power connectors does the PWS-501P-1R require to work?

The PWS-501P-1R is an ATX unit, so it needs a standard 24-pin main connector and a 4-pin or 8-pin CPU power connector from your motherboard.

Will the 500W output and Resonant LLC topology support older components that draw more power at startup?

The 500W capacity and Resonant LLC topology with DC-to-DC conversion deliver stable power for legacy parts during high inrush currents at boot.

How do I confirm the Zero RPM fan mode is active on the PWS-501P-1R?

Under light loads the fan stops completely; you will hear no fan noise and the 80 PLUS Gold efficiency rating indicates low-load operation is within spec.
