650W ATX 3.1 power supply

The ASRock SL-650G delivers 650 W of continuous power for mainstream desktop builds. It follows the ATX 3.1 specification and uses a fully modular cable design so only the required leads are installed. Japanese capacitors rated at 105 °C provide long-term reliability under load. The unit carries 80 PLUS Gold and Cybenetics Platinum efficiency certifications.

Cybenetics Lambda A+ acoustics

A 135 mm striped axial fluid-dynamic-bearing fan runs under iCool intelligent control to keep noise below 20 dB on average. The herringbone blade structure and fluid seal reduce turbulence while extending bearing life. 80 PLUS Gold certification means typical efficiency above 80 percent at common loads, lowering waste heat and overall power draw. The platform also includes a built-in 5 V boost function for stable low-voltage delivery.

Full modular connectivity for clean builds

The supply ships with a 24 pin ATX connector, two 8 pin (4+4) EPS cables for the CPU, and two 8 pin (6+2) PCIe cables for graphics cards. Three 4 pin peripheral and six SATA connectors cover drives and accessories. At 175 mm long the unit fits standard ATX cases without intruding on drive bays or long graphics cards. A full protection suite safeguards components across normal and extreme operating conditions.
