  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw and heat via 80 PLUS Gold efficiency
  • Near-silent operation thanks to Zero RPM fan mode
  • Cleaner power delivery using resonant LLC with DC-to-DC conversion
  • 450 W ATX output for reliable system performance

Modern Standby ATX PSU for Efficient Builds

This 450W ATX power supply carries 80 PLUS Gold certification for high-efficiency operation and lower heat output. It is designed for desktop systems that support Modern Standby, delivering fast wake-from-sleep times and improved low-load efficiency. The Resonant LLC topology with DC-to-DC conversion ensures clean, consistent power delivery and reduced coil whine.

Verify ATX Clearance and Connector Needs

Before ordering, confirm your chassis accepts a standard ATX form-factor unit and that the fixed cable set matches your motherboard, CPU, GPU and storage connectors. Check that the 450W capacity aligns with your component power draw, especially if you run a discrete graphics card. Ensure the rear mounting pattern and depth suit your case layout without obstructing airflow or other components.

Zero RPM Mode and LLC Topology Cut Noise

The Zero RPM fan mode stops the cooling fan completely at low and medium loads, enabling near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion further reduces coil whine and supports deeper, more energy-efficient sleep states. Together, these features lower acoustic output and improve power quality without extra software or hardware.
