280W ATX Power Supply

The KHACHIMO DPS-280KB A delivers 280W of continuous power in a standard ATX form factor. It is designed for desktop systems requiring reliable, efficient energy conversion. The unit carries 80 PLUS Gold certification, confirming high efficiency across typical load ranges. Modern Standby compatibility enables rapid wake-from-sleep transitions for responsive daily use.

Build integration and space savings

As a standard ATX power supply, it fits conventional chassis mounting points without special brackets. The Resonant LLC topology with DC-to-DC conversion provides stable voltage rails for sensitive components. Zero RPM fan mode stops the cooling fan at low and medium loads, removing acoustic distraction during office work or media playback. High efficiency reduces waste heat, easing the thermal load on case airflow.

Included compatibility references

The supplier lists multiple replacement part numbers including 45J9425, 45J9423, PC7032, PC9019, PS-5281-01VF, PC7001, 41A9702 and 41A9715. These identifiers help installers verify fitment against existing hardware documentation. No modular cables or software utilities are mentioned in the supplied data. Builders needing higher wattage or specialised connectors should confirm requirements before purchase.

Questions about this item

At what sustained load does the 280 W limit become the binding constraint?

The unit is rated for 280 W continuous output; exceeding that limit will trigger protection and shut the system down.

How loud is the fan and how hot does the supply run during all-day operation?

Zero RPM mode stops the fan completely at low and medium loads, while 80 PLUS Gold efficiency keeps waste heat and noise to a minimum.

Which motherboard power connectors must already be present for this ATX unit to work?

A standard 24-pin ATX connector and the matching 4-pin or 8-pin CPU power header are required on the motherboard.
