KHACHIMO 775W ATX Power Supply PS-2771-3 M77050-001

775W ATX Power Supply for Modern PCs

This KHACHIMO unit delivers 775 watts through an ATX form factor and carries 80 PLUS Gold certification for high efficiency. It targets builders who need reliable power for mainstream desktop components and want lower electricity draw at typical loads. The PS-2771-3 model includes Modern Standby compatibility so the system resumes from sleep almost instantly. It is not for users who require redundant or server-grade power modules.

Thermals, Noise and Efficiency at Typical Loads

Zero RPM fan mode stops the cooling fan completely at low and medium loads, giving near-silent operation during everyday tasks. The 80 PLUS Gold rating means less waste heat, which keeps internal temperatures lower and reduces overall system noise. Resonant LLC topology with DC-to-DC conversion supplies clean power and cuts coil whine for quieter performance. Buyers who need active cooling at all times should note the fan-off behaviour.

Behaviour Under Sustained Load

Under continuous demand the resonant LLC design maintains stable voltage regulation and consistent efficiency. DC-to-DC conversion supports deeper sleep states even during prolonged sessions, while the Gold-rated platform limits temperature rise compared with lower-tier units. The fan engages only when thermal thresholds demand it, preserving acoustic comfort. This unit is not designed for extreme overclocking scenarios that push well beyond its rated capacity.
