ATX power supply for modern builds

This ATX form-factor unit fits standard desktop chassis and delivers the stable rails a contemporary system requires. Its 80 PLUS Gold certification means high efficiency across typical loads, reducing waste heat and keeping electricity use lower. Modern Standby compatibility allows near-instant wake from sleep for a responsive desktop experience. The resonant LLC topology with DC-to-DC conversion supplies clean power to sensitive components.

Cabling and clearance for system integration

The modular approach frees up space inside the case by letting you connect only the cables your build actually needs. DC-to-DC conversion handles minor rails efficiently, which simplifies the internal layout and reduces clutter around the motherboard tray. Modern Standby support works with compatible motherboards to enable deeper sleep states without extra configuration. This unit suits builders who want a tidy interior and reliable power delivery.

Thermals noise and power behaviour

Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent operation during everyday tasks. The 80 PLUS Gold rating ensures high efficiency, which directly lowers heat output and keeps internal temperatures down. Resonant LLC topology reduces coil whine for quieter performance under varying loads. Together these features provide cool, quiet running for typical desktop workloads.
