KHACHIMO 530W ATX Power Supply YM-2531B 80 PLUS Gold

530W ATX Power Supply for Modern Standby Builds

This KHACHIMO unit delivers 530W through an ATX form factor and carries 80 PLUS Gold certification for high efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and supports modern energy-efficient sleep states. It suits system builders who want lower power consumption, reduced noise and cooler temperatures in a standard desktop chassis.

Practical Limits of the ATX Standard

The ATX form factor fits most mainstream cases, but physical clearance and cable routing space vary by chassis design. The 530W rated output sets the maximum combined load across all rails, so configurations with multiple high-end graphics cards or heavily overclocked CPUs may exceed this capacity. The unit enables Modern Standby fast wake times, yet actual wake speed also depends on motherboard firmware and operating-system support.

Checks Before Ordering

Verify that your case accepts a standard ATX power supply and that the available cable connectors match your motherboard, CPU and graphics-card requirements. Confirm the total system power draw under full load stays within the 530W rating to avoid instability. Ensure the motherboard supports Modern Standby if you rely on the fast wake-from-sleep feature.
