400W ATX Power Supply

The KHACHIMO 400W ATX unit is a new 80 PLUS Gold certified power supply designed for systems that require efficient, low-noise power delivery. It suits builders assembling workstations or compact PCs where Modern Standby support and quiet operation are priorities.

80 PLUS Gold efficiency

Certified at 80 PLUS Gold, the supply maintains high efficiency across typical loads, reducing waste heat and lowering overall power consumption. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent voltage while minimising coil whine.

Modern Standby and silent cooling

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. This unit replaces FSP300-70MP or FSP400-70MP models; builders needing higher wattage or modular cables should look elsewhere.
