Seasonic CORE GM-650 (2019)

Introduced in 2019, the Seasonic CORE GM-650 (SSR-650LM) is the semi‑modular, 80 Plus Gold member of Seasonic’s CORE family, positioned between the fully modular GX and fixed‑cable GC lines. It is now listed by Seasonic as a discontinued product. As a mainstream PSU, it exists to deliver Gold‑tier efficiency, proven component quality, and a 7‑year warranty at an accessible price. The 650 W, ATX‑size unit provides four 6+2‑pin PCIe connectors on two cables, making it a good fit for single‑GPU mid‑range gaming towers while reducing cable clutter. It uses 105 °C Japanese electrolytic capacitors and follows ATX12V spec, with no ATX 3.0/3.1 features or native 12VHPWR (adapters required if needed). Notable: Cybenetics Gold efficiency with an A‑class noise rating.
