Product overview

Introduced in 2019 as part of Seasonic’s FOCUS GX (Gold) refresh that replaced the FOCUS Plus line, the Focus GX‑1000 (SSR‑1000FX) is the 1000 W member of that family. Within PSUs it lands in the flagship tier by wattage: a fully modular, 80 PLUS Gold ATX unit built to supply demanding systems with clean cabling and a long 10‑year warranty. It’s well‑suited to high‑end GPU builds and users who want extra headroom for future upgrades or light overclocking. Notable for its compact 140 mm‑deep chassis and Seasonic’s Hybrid Fan Control with a fanless mode. This original non‑ATX 3.0 revision (no native 12VHPWR) is now discontinued.
