ATX power supply for modern standby systems

This 350W unit is built for PCs that rely on fast wake-from-sleep and low-load efficiency. The 80 PLUS Gold rating means less wasted energy and cooler running temperatures. It suits compact or quiet-focused builds where silent idle operation matters.

350W capacity with Gold efficiency headroom

At typical desktop loads the supply runs well within its rating while the Gold certification keeps heat and fan noise down. The Zero RPM mode stops the fan entirely at low and medium loads for near-silent use. Sustained draws above 350W will exceed the unit's rated output and require a higher-capacity model.

Resonant LLC topology with DC-to-DC conversion

This design delivers clean, consistent power and reduces coil whine for quieter operation. It also enables the energy-efficient sleep states that modern standby demands. Systems without modern standby support will not benefit from the fast wake capability.

Questions about this item

Will this 350W ATX unit fit and power a legacy system that still uses a 24-pin motherboard connector and older peripheral plugs?

The supply follows the ATX form factor and provides standard 24-pin, CPU and peripheral connectors, so it will install directly into older chassis and motherboards that expect those interfaces.

How can I verify the Zero RPM fan mode is actually engaging after I build the PC?

Under light loads the fan stops completely; you can confirm it is working by listening for silence at idle and watching the fan blades remain stationary through the case vent.

Does the K30047B box include mounting screws and a power cord, or must I source them separately?

The package contains the power supply unit, mounting screws and an AC power cord, so no extra parts are required for a standard installation.
