ATX power supply with Modern Standby support

The KHACHIMO CA2000-0020 G2 CA4030-0201 G1 is an ATX power supply built for systems that use Modern Standby sleep states. It targets builders who want fast wake times and high efficiency at low loads. The unit carries 80 PLUS Gold certification for reduced energy waste. It is not for users who need a different form factor or higher wattage than the model provides.

Sustained load behaviour with LLC resonant topology

Under continuous demand the resonant LLC topology with DC-to-DC conversion delivers stable voltages and tight regulation. The design minimises coil whine and supports efficient transitions between power states. Clean power output is maintained across the operating range without the ripple spikes seen in simpler designs. Builders relying on all-night compute loads will see consistent performance.

Thermals, noise and power draw in normal use

The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. When the fan does spin, the 80 PLUS Gold efficiency keeps waste heat low, helping case temperatures stay down. Modern Standby compatibility further reduces draw during sleep. The combination results in quiet, cool running for typical desktop workloads.

Perguntas sobre este artigo

How loud is the 80 PLUS Gold CA2000-0020 G2 when it runs all day?

The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, and the 80 PLUS Gold efficiency keeps heat and noise low under sustained use.

What cables or connectors must I already have to install the CA4030-0201 G1?

It uses a standard ATX form factor, so your case must accept ATX units and your motherboard needs the usual 24-pin ATX and CPU power connectors.

Will the Resonant LLC DC-to-DC design work reliably with an older motherboard that lacks Modern Standby?

Yes, the topology delivers clean, consistent power and reduces coil whine on any ATX-compatible board, while Modern Standby support simply remains unused.
