Product overview

Launched in 2021 as part of Seasonic’s FOCUS SGX (2021) refresh, the Focus SGX-750 is a 750 W SFX unit within the FOCUS family. It offers 80 PLUS Gold efficiency, fully modular cabling, Hybrid Silent Fan Control with fanless operation at light loads (about 30%), and a 10‑year warranty.

Positioned as a high_end SFX option, it exists to deliver high wattage in very compact cases without cable clutter. It’s well-suited to SFX/small‑form‑factor builds and mid‑range gaming with some headroom/overclocking. Note that it is not ATX 3.x and lacks native 12VHPWR; newer GPUs may require a 2×8‑pin to 12VHPWR cable. Includes an SFX‑to‑ATX mounting bracket. Not discontinued as of July 2026.
