KHACHIMO SFX 250W Power Supply

The KHACHIMO SFX unit delivers 250 watts of continuous power in a compact ATX form factor designed for DVR and NVR systems. 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 provides clean, consistent output while reducing coil whine.

Suits compact recorder builds needing eight SATA

This supply fits small-form-factor DVR or NVR enclosures that require up to eight SATA power connections and value quiet operation through the zero RPM fan mode at low and medium loads. Builders needing higher wattage for discrete graphics cards or additional PCIe connectors should look at alternative units with greater output capacity and different cable configurations.

Sustained load behaviour with Gold efficiency

Under continuous demand the resonant LLC design maintains stable voltage regulation while the 80 PLUS Gold rating keeps waste heat and fan noise lower than less efficient designs. The zero RPM mode remains inactive once load rises past the medium threshold, allowing the fan to spin only as fast as thermal conditions require for reliable long-term operation.

Questions about this item

Does this PSU include the eight SATA connectors my DVR or NVR drives need?

The supplier title lists eight SATA connectors, so the unit ships with enough plugs for eight drives.

Will the SFX form factor and ATX type fit alongside my existing ATX motherboard and case?

It is an SFX unit with ATX electrical specification; it fits SFX cases and works with standard ATX motherboards using the included bracket.

How can I confirm the Zero RPM fan mode is actually silent under light loads?

With the system idle or under low load the fan should stop spinning completely; listen for no fan noise to verify the mode is active.
