Ruth's sister 600W ATX internal power cable

600 W non-modular desktop PSU

This 600 W non-modular power supply delivers rated output of 600 W with a peak capacity of 750 W for desktop systems. It includes a 20+4 pin ATX connector, two 4+4 pin CPU connectors and two 6+2 pin PCIe connectors plus SATA and legacy IDE leads. Active PFC operates across a 90 V to 265 V input range.

Check connector count and case clearance

Verify that your motherboard requires both 4+4 pin CPU connectors and that your graphics card uses one or two 6+2 pin plugs. The fixed cable bundle adds five SATA ports and multiple IDE leads, so ensure routing space behind the motherboard tray. A single 120 mm fan handles airflow.

Steady 85 % efficiency up to 40 °C

Under sustained load the unit maintains 85 % efficiency while the 120 mm fan manages heat within an operating range of 10 °C to 40 °C. Peak output of 750 W is available for short bursts, but continuous draw should stay at or below the 600 W rating. Storage extremes reach -40 °C to 70 °C.
