280 W ATX power supply for office PCs

This 280 W ATX unit from KHACHIMO is built for compact desktop systems that need reliable, efficient power. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.

Check ATX fit and 280 W headroom

Verify that your chassis accepts a standard ATX power supply and that the 280 W continuous rating covers your CPU, graphics card, drives and peripherals combined. Confirm the cable set matches your motherboard, GPU and storage connectors before ordering. Ensure the unit’s physical depth clears any drive cages or motherboard components in your case.

Gold efficiency with zero-RPM fan

80 PLUS Gold operation keeps waste heat and noise low during typical workloads. The zero-RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states for day-to-day quietness.

Questions about this item

What comes in the box with the PS-5241-01VF and do I need to buy any cables separately?

The package includes the 280W ATX power supply unit only; standard ATX power cables are attached, so no separate cable purchase is required for a typical desktop build.

The supplier title lists several model numbers — which one should I choose for my system?

PS-5241-01VF is the correct part number; the other codes such as PC7071, PC7001, PC7032, PC9023, HK340-85FP and DPS-280HB A are cross-references for compatible replacements.

What does the 280W rating mean for everyday use in a PC?

It delivers up to 280 watts of continuous power, suitable for office desktops or small-form-factor systems with integrated graphics and modest component counts.
