KHACHIMO X4270 N4288 VD650 E450 6Pin 400W Power Supply

KHACHIMO 400W ATX Power Supply

The KHACHIMO X4270 N4288 VD650 E450 is a 400W ATX power supply designed for desktop systems that require reliable and efficient power delivery. It carries 80 PLUS Gold certification, indicating high efficiency across typical loads, which helps reduce electricity consumption and heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Ideal for efficient quiet builds not for high

This unit suits builders assembling office PCs, home media centres or compact workstations where low noise and high efficiency are priorities. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. Systems with power-hungry discrete graphics cards, multiple drives or heavy overclocking should look at higher-capacity units because the 400W limit and single 6-pin connector restrict available power for demanding components.

Fits standard ATX cases

The ATX form factor fits standard chassis layouts and the 6-pin PCIe connector supports mid-range graphics cards. Modern Standby support requires a compatible motherboard to enable fast sleep and wake functionality. The Gold-rated efficiency and Zero RPM mode free up thermal headroom inside the case, allowing quieter system cooling overall. Ensure the motherboard provides the necessary ATX power connectors and that total system draw stays within the 400W rating.
