KHACHIMO 700W ATX Power Supply 80 PLUS Gold Zero RPM Fan LLC DC-DC

700W ATX Power Supply for Modern Standby PCs

The KHACHIMO 700W ATX unit delivers 80 PLUS Gold certified efficiency for desktop builds that rely on fast wake-from-sleep behaviour. Its LLC resonant topology with DC-to-DC conversion supplies clean, consistent power across the rails. The design targets system integrators and enthusiasts who want lower energy loss and support for modern low-power sleep states. It is not suited for buyers who need redundant or hot-swap power modules.

Sustained load behaviour with LLC DC-DC topology

Under continuous demand the resonant LLC stage combined with DC-to-DC conversion maintains tight voltage regulation and reduces coil whine. The platform handles prolonged workloads without the efficiency drop-off seen in simpler group-regulated designs. Ripple stays suppressed during extended sessions, protecting sensitive components. Builders who require multi-GPU power distribution beyond a single 700W unit should look elsewhere.

Thermals, noise and power draw in normal use

The Zero RPM fan mode stops the fan completely at low and medium loads, yielding near-silent operation during typical desktop tasks. 80 PLUS Gold certification means less waste heat enters the case, keeping internal temperatures lower. When the fan does spin, the LLC topology helps minimise acoustic signature. Users who prefer active cooling at all times cannot disable the semi-passive logic.
