Target Components

The Seasonic CORE GC 650W is a compact fixed-cable ATX 3.1 power supply designed for reliable gaming, home and business PC builds. Its 80 PLUS Gold certification provides efficient power delivery, while a 120mm Hydro Dynamic Bearing fan with Smart and Silent Fan Control helps keep cooling noise under control. The 650W model meets ATX 3.1 requirements using conventional PCIe 6+2-pin graphics connectors rather than a 12V-2x6 cable. The compact 140mm chassis and durable black braided-pattern cables make it suitable for a wide range of modern systems.
