KHACHIMO 280W ATX power supply PS-5281-02 PC6001

280W ATX power supply for compact builds

The KHACHIMO PS-5281-02 PC6001 delivers 280 watts of continuous power in a standard ATX form factor. It is designed for small-form-factor desktops, office workstations and media PCs that demand reliable delivery without the bulk of higher-wattage units. The 80 PLUS Gold certification ensures efficient conversion across typical loads.

Replaces older low-efficiency units

This supply upgrades systems still running group-regulated or bronze-rated designs that waste energy at idle and produce audible fan noise. The jump is worthwhile when a build requires Modern Standby support for instant wake, quieter operation under light loads, or tighter voltage regulation for sensitive components. It is not suited for configurations with discrete graphics cards or multiple drives that exceed the 280W budget.

Limits of the ATX 280W envelope

The 280W ceiling restricts use to platforms with integrated graphics, low-power CPUs and modest storage counts. Zero RPM mode operates only while total draw stays within the low-to-medium range defined by the unit's fan curve. Resonant LLC topology with DC-to-DC conversion improves transient response, yet the fixed maximum output remains the hard boundary for any future component additions.
