400 W ATX power supply

The KHACHIMO BEA-640 is a 400 W ATX power supply built for desktop computers that require a standard mains input. It suits builders assembling or repairing a system with modest power demands. Tested and confirmed working before dispatch.

Build quality and connectors

The unit follows the ATX form factor so it fits regular chassis mounting points and aligns with standard motherboard power headers. Cables reach the mainboard, drive and peripheral connectors without adapters. Good-quality components are used throughout to support stable daily operation.

Deciding specification

The continuous 400 W rating is the single figure that determines whether this supply matches your build. Systems with high-end graphics cards or multiple drives will exceed this ceiling and need a higher-capacity unit. Choose this model only when the total component draw stays within 400 W.

Questions about this item

What does the ATX form factor mean for compatibility with my case?

The ATX form factor matches standard ATX cases and motherboards, so the unit fits the usual mounting points and supplies the 24-pin motherboard connector plus CPU and peripheral power leads.

What physical space and mounting does this 400W unit require?

It fits a standard ATX power-supply bay with four rear mounting screws; check your case depth to ensure the 14 cm length clears drive cages or cables.

What is the correct way to install the BEA-640 and avoid the common mistake?

Secure the unit with all four screws, connect the 24-pin and CPU power cables firmly, then route cables before powering on; the step often missed is seating the 24-pin connector fully until it clicks.
