KHACHIMO PWS-781-1S 780W ATX power supply

780W ATX power supply for modern PCs

The KHACHIMO PWS-781-1S delivers 780 watts of continuous power in a standard ATX form factor. It targets system builders who need reliable energy delivery for mid-to-high-end components. Gold-rated efficiency keeps waste heat and electricity costs down. Modern Standby support ensures rapid wake times and improved low-load behaviour.

Upgrade from lower-wattage or Bronze units

Replacing a lower-capacity or Bronze-rated supply with this 780W Gold model adds headroom for powerful GPUs and CPUs while cutting idle power draw. The jump is worthwhile when the old unit runs near its limit, produces coil whine, or lacks Modern Standby compatibility. Zero RPM fan mode then eliminates noise at typical desktop loads. Resonant LLC topology with DC-to-DC conversion further stabilises voltage rails.

Handles multi-GPU and overclocked builds

This unit comfortably powers demanding single-GPU configurations and many dual-GPU setups with high-end processors. It runs out of headroom only when total system draw approaches the 780W rating under sustained synthetic loads. Clean power delivery supports stable overclocking within that envelope. Builders planning extreme multi-card arrays or sub-zero cooling should verify their peak draw first.
