300 W ATX Power Supply for Compatible Systems

This 300 W ATX power supply delivers Modern Standby compatibility for extremely fast wake-from-sleep times and better low-load efficiency. It carries 80 PLUS Gold certification for high efficiency operation that reduces power consumption, noise, and temperatures. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suitable for Systems Requiring Modern Standby

Builders who need a 300 W ATX unit with Modern Standby support and Gold-class efficiency will find the feature set aligned. Those who require higher wattage, a different connector layout, or a form factor other than ATX should look at alternative units. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Standard ATX Installation with Fan Behaviour to Note

Installation follows the normal ATX mounting pattern and connector routing for compatible chassis and motherboards. The Zero RPM mode means the fan will remain off at low and medium loads, which is normal behaviour and not a fault. Resonant LLC topology with DC-to-DC conversion helps minimise coil whine for quieter operation.

Perguntas sobre este artigo

What motherboard power connector does the 12Pin 300W ATX unit require?

It uses a 12-pin ATX connector, so your motherboard must provide a matching 12-pin socket.

Will the DPS-300AB-82A work with a legacy system that only has a 20-pin or 24-pin ATX header?

No, this supply has a 12-pin output and cannot connect to standard 20-pin or 24-pin motherboard headers without an adapter.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light load the fan should stay completely still; you can verify by watching the fan blades while the system idles.
