290W ATX Power Supply for DVR and NVR Systems

The KHACHIMO DPS-280AB-7A is a new 290 watt ATX power supply designed for digital video recorders and network video recorders. It delivers 80 PLUS Gold certified efficiency for lower power consumption and cooler operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine.

Suits Security Appliances Requiring ATX Power

Builders of DVR or NVR units needing an ATX form factor with 80 PLUS Gold efficiency will benefit from the zero RPM fan mode that stops the fan at low and medium loads for near-silent running. Systems that require a higher wattage output than 290 watts or a different form factor such as SFX or TFX should look at alternative power supplies. Installations without an ATX mounting location cannot use this unit.

290 Watt Output Decides Fit for Recorder Builds

The single specification that determines whether this power supply fits the build is the 290 watt rated output. If the recorder and its drives draw more power than this rating the system will be unstable or fail to start. When the total load stays within 290 watts the Gold efficiency, Modern Standby support and resonant LLC design deliver reliable, quiet power for continuous recording duty.

Questions about this item

What motherboard power connectors does the DPS-280AB-7A require to turn on?

The unit uses a standard 24-pin ATX main connector plus a 4-pin or 8-pin CPU auxiliary connector.

Will the 290W capacity handle a system that still runs a mechanical hard drive and an older graphics card?

Yes, provided the combined draw of the CPU, GPU, drives and peripherals stays within the 290W rated output.

How can I confirm the Zero RPM fan mode is active after assembly?

Power on the PC at idle; the fan should remain stationary until the internal temperature rises above the trigger threshold.
