Product overview

Announced on July 20, 2012 and reaching retail in early August 2012, the SilverStone ST45SF-G is an early SFX-series 450 W unit with 80 PLUS Gold efficiency and fully modular cabling. It uses a compact 100 mm–deep SFX chassis with a single +12 V rail rated at 37 A and ships with an SFX‑to‑ATX bracket for broader case compatibility.

Positioned as high_end for its time (Gold + fully modular), it exists to bring efficient, tidy power delivery to space‑constrained builds. It’s a solid fit for SFX/small‑form‑factor systems and mid-range gaming setups that don’t need ATX 3.0 or native 12VHPWR support. Notable: it was among the first SFX units to pair 80 PLUS Gold efficiency with fully modular cables. Discontinuation status is not clearly stated by the manufacturer.
