500W ATX Power Supply for Modern Standby

The KHACHIMO HK600-18FP is a 500W ATX power supply built for systems that use Modern Standby sleep states. It delivers 80 PLUS Gold certified efficiency to reduce power draw and heat. The resonant LLC topology with DC-to-DC conversion provides clean power and supports low-load sleep modes. It suits builders who want quiet, efficient operation in a standard ATX form factor.

Check ATX compatibility and connector needs

Verify that your case accepts a standard ATX power supply and that your motherboard uses the 24-pin ATX and required CPU power connectors. Confirm the total system power draw stays within the 500W rating. The unit’s Modern Standby support requires a compatible motherboard and operating system to enable fast wake times. Ensure your build does not require more connectors than the unit provides.

Fits standard ATX builds with quiet cooling

The supply fits typical ATX chassis layouts and uses a Zero RPM fan mode that stops the fan at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports energy-efficient sleep states. It frees the builder from noisy fan curves while delivering stable power for Modern Standby systems. The 80 PLUS Gold rating helps keep internal temperatures lower under load.

Questions about this item

What cables and connectors are included with the HK600-18FP, and which ones must I purchase separately?

The box contains the 500W ATX power supply with its fixed cable set. No modular cables or extra adapters are supplied, so any specialised connectors your build needs must be sourced separately.

The model name includes 600 but the headline rating is 500W — which capacity should I trust for my build?

The continuous output rating is 500W. The 600 figure in the model designation is a series identifier, not a wattage rating, so size your components to the 500W limit.

What does the 80 PLUS Gold badge mean for daily power draw and thermals inside my case?

It guarantees high efficiency across typical loads, which lowers electricity use, cuts waste heat and lets the Zero RPM fan stay off longer for quieter operation.
