12 V 25 A ATX power supply

This ATX power supply delivers 12 V at up to 25 A from a 36 V to 75 V input range. The 300 W design is built for modern desktop builds that require strong single-rail performance and fast wake-from-sleep behaviour. It carries an 80 PLUS Gold certification for high efficiency across typical loads.

Builders needing silent low-load operation

The Zero RPM fan mode stops the fan completely at low and medium loads, making the unit suitable for quiet workstations or media PCs. Modern Standby support enables extremely fast resume times. Systems that demand multiple 12 V rails, higher total wattage, or input voltages outside the 36 V to 75 V window should consider other designs.

Fits standard ATX cases with DC input

The supply installs in any ATX chassis and connects to a 36 V to 75 V DC source, freeing the build from an AC mains cord. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine. Ensure your chassis airflow can handle the unit's thermal output when the fan engages under heavy load.

Spurningar um þessa vöru

What motherboard power connectors does the AVQ300-48S12-6L require to be present on my board?

The unit follows the ATX form factor, so your motherboard must provide a standard 24-pin ATX connector plus the appropriate CPU and PCIe power headers for your components.

Will the 12 V 25 A output and 36-75 V input range work with older drives and expansion cards I plan to keep?

Yes, the 12 V rail delivers up to 25 A and the DC-to-DC conversion maintains tight regulation, so legacy hard drives, optical drives and add-in cards that draw from 12 V will operate normally.

How can I verify the Zero RPM Fan Mode is actually engaging after I build the system?

Under light or medium load the fan stops completely; you can confirm it by watching the fan blades while the system idles — they should remain still until the load increases.
