Product information

Description

The Seasonic CORE GC-650 ATX 3.1 is a fully modular 650 W power supply designed for modern desktop PCs. Compliant with ATX 3.1 and PCIe 5.1 standards, it delivers 650 W of continuous power with 80 PLUS Gold efficiency. The unit features a 24-pin ATX motherboard connector, a 120 mm active cooling fan with Seasonic’s Smart and Silent Fan Control (S2FC), fully modular braided black cables, and native support for next‑generation and legacy GPU connectors. The design includes Seasonic’s new OptiSink PCB and thermal layout to improve heat dissipation, reliability, and allow safe installation in any orientation. A 7-year manufacturer’s warranty covers the product.

Advantages

The CORE GC-650 combines ATX 3.1 and PCIe 5.1 compliance with 80 PLUS Gold efficiency to provide reliable power delivery and reduced energy losses. Fully modular cabling and braided black cables simplify system building and cable management. The OptiSink redesign and automated PCB manufacturing increase thermal performance and long-term reliability while enabling flexible installation orientation. S2FC balances cooling needs and acoustics to keep noise low under typical loads. Included native 12V-2x6 and 2×8-pin GPU connections and adapter support improve compatibility with both next‑gen and legacy graphics cards.
