650 W ATX power supply for modern standby builds

This KHACHIMO unit delivers 650 W of continuous power through an ATX form factor. It targets builders who want a new supply that supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. The design suits standard desktop chassis that accept ATX power supplies and require a single 650 W source.

Fits ATX cases and frees low-load noise

The supply mounts in any ATX-compatible case and connects to the motherboard and components with standard ATX cabling. Its Zero RPM Fan Mode stops the cooling fan completely at low and medium loads, removing audible fan noise during idle or light work. Resonant LLC topology with DC-to-DC conversion reduces coil whine and enables deeper sleep states without extra hardware.

Gold efficiency and stable output under load

80 PLUS Gold certification confirms high efficiency across typical loads, lowering heat output and overall power draw. The LLC resonant topology maintains clean, consistent voltage delivery during sustained workloads, while the fan remains off until higher thermal thresholds are reached. This combination keeps temperatures and acoustic levels controlled over long sessions.

Questions about this item

How does the 80 PLUS Gold certification affect efficiency and heat during all-day use?

The 80 PLUS Gold rating means the unit runs at high efficiency, lowering power draw and keeping temperatures cooler during sustained operation.

Does the Zero RPM fan mode stay off under continuous medium loads?

Yes, the fan switches off entirely at low and medium loads, giving near-silent operation even during extended sessions.

What motherboard power connector does this ATX unit require to function?

It uses the standard ATX 24-pin main connector plus the CPU 4+4-pin connector found on modern motherboards.
