280 W ATX power supply

This new KHACHIMO unit delivers 280 watts through an ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean power delivery. Modern Standby compatibility enables fast wake-from-sleep and improved low-load efficiency.

Suits DVR and NVR builds needing 280 W

The supply fits DVR and NVR systems such as the 7816N POE that require a 280 W ATX source. Its zero RPM fan mode keeps operation near-silent at low and medium loads. Builders needing more than 280 W or a different form factor should look elsewhere.

280 W ATX output decides fit

The single specification that determines compatibility is the 280 W ATX output rating. If your chassis and components demand exactly this wattage and form factor the unit will work; otherwise it will not.

Questions about this item

How quiet is the 280W unit during all-day operation?

The 80 PLUS Gold design runs cooler and the Zero RPM fan mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for near-silent running.

What connectors or hardware must I already have to install this ATX supply?

A standard ATX motherboard socket, case mounting points and the usual 24-pin, CPU and peripheral cables are required; the unit is a direct replacement for any ATX-form-factor PSU.

Will the 280W PSU work reliably with older components I want to keep?

Modern Standby support and the DC-to-DC conversion provide clean, stable rails that older drives and expansion cards expect, so legacy hardware runs without compatibility issues.
