DVR NVR 20-Pin Power Supply

The KHACHIMO unit is a 250 W ATX power supply built for DVR and NVR recorders that require a 20-pin main connector. It delivers eight SATA power connectors to run multiple surveillance drives from a single source. The 80 PLUS Gold rating confirms high efficiency across typical loads. Modern Standby compatibility enables rapid wake-from-sleep behaviour for always-on recording systems.

Sustained Load Behaviour

Under continuous operation the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and suppresses coil whine. The Zero RPM fan mode stops the fan completely at low and medium loads, so the chassis stays near-silent during long idle periods. When the load rises the fan spins up gradually, maintaining stable temperatures without abrupt speed changes. Gold-certified efficiency reduces waste heat, helping the unit run cooler during 24/7 duty cycles.

Upgrade Context

This supply replaces older ATX units that lack the 20-pin connector or sufficient SATA leads for modern recorder backplanes. The jump is worthwhile when the existing unit cannot wake quickly from sleep or produces audible coil noise under light loads. It is not suited for builds that need a 24-pin main connector or more than eight SATA power outputs. Builders requiring higher total wattage or PCIe power cables should look elsewhere.

Questions about this item

How loud and hot does the 250W unit get when running all day?

The 80 PLUS Gold certification and Zero RPM fan mode keep noise and heat low; the fan stays off at low and medium loads, reducing coil whine and temperature.

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

The unit provides eight SATA power connectors on a 20-pin harness, so your drives or backplanes need matching SATA power inputs.

Will this ATX supply work with older motherboards I want to keep?

Yes, the ATX form factor and DC-to-DC conversion deliver stable voltages compatible with legacy boards, while Modern Standby support adds faster wake times.
