KHACHIMO N2200-PAC-400W 400W power supply

ATX 400W desktop power unit

This ATX power supply delivers 400W of continuous power for standard desktop computers. It suits builders assembling a basic office or home system that does not demand high-wattage components. The unit is new and has been tested for correct operation before shipment.

Practical limits of the ATX form factor

The ATX design fits most mainstream chassis but cannot supply the sustained current needed for multi-GPU arrays or heavily overclocked platforms. Systems with numerous drives or high-end graphics cards will exceed the 400W ceiling and require a higher-rated unit. This supply is therefore limited to modest single-GPU or integrated-graphics configurations.

400W maximum output decides fit

The 400W rating is the single figure that determines whether this unit matches your build. If your component list stays within that envelope the supply will handle the load; if the total draw is higher you must choose a larger model. No other specification overrides this capacity limit.
