  • 80 PLUS Gold certification delivers high efficiency, lower consumption and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • ATX form factor supplies 12 V at 25 A for compatible systems

12 V 25 A ATX power supply

This unit delivers 12 V at 25 A for systems that require a dedicated ATX source. It is intended for builders replacing a compatible module or integrating a secondary rail in a custom chassis.

Standard ATX mounting with fixed cables

The supply fits regular ATX screw patterns and uses a fixed cable set, so cable routing is straightforward. The main risk is connector mismatch if the target board expects a different pinout or additional rails.

Verify the 12 V rail current and connector layout

Confirm that the existing hardware draws no more than 25 A on the 12 V rail and that the ATX connector pinout matches the motherboard or backplane. Without the exact board specification the fit cannot be guaranteed.
