Overview

The Seasonic CORE GC-650 is a 650W ATX 3.1 power supply rated 80 PLUS Gold. It suits builders who need a compact, non-modular unit with dual 8-pin PCIe connectors for modern graphics cards.

Power Delivery and Compliance

The unit delivers 650 watts total power with a single 12V rail rated for 648 watts. It meets the ATX 3.1 standard and supports PCIe 5.1 power requirements. Two 8-pin PCIe connectors are provided for graphics cards; a native 12V-2x6 connector is not included.

Efficiency and Cooling

80 PLUS Gold certification ensures high conversion efficiency, reducing waste heat and power draw. A 120mm hydrodynamic bearing fan uses S2FC intelligent control to adjust speed based on temperature, keeping noise low at idle and providing strong airflow under load.

Build and Protection

The non-modular design uses fixed black cables with a braided sleeve. At 140mm deep, the chassis fits tight ATX builds. Protection circuits cover overcurrent, overload, overtemperature, overvoltage, undervoltage, and short circuit. Seasonic backs the unit with a five-year manufacturer warranty.
