800W ATX Power Supply for Modern PCs

This KHACHIMO DPS-800GB-3A unit delivers 800W of continuous power through an ATX form factor. It targets builders who need Gold-certified efficiency and Modern Standby support for fast wake times. The resonant LLC topology with DC-to-DC conversion ensures clean power delivery for stable system operation.

80 PLUS Gold Efficiency and Load Limits

The 80 PLUS Gold certification guarantees high efficiency at typical loads, reducing waste heat and lowering electricity costs. Zero RPM fan mode keeps the unit silent at low and medium loads by stopping the fan entirely. At heavier loads the fan spins to maintain safe temperatures, so silence is not guaranteed under full 800W draw.

Check ATX Fit and Cable Reach Before Buying

Verify that your case accepts a standard ATX power supply and that the included cables reach all components. Confirm your motherboard supports Modern Standby to use the fast wake feature. Builders who need higher wattage or a different form factor such as SFX should look elsewhere.
