Product overview

Announced on November 6, 2020 and first sold in markets like Japan from January 29, 2021, the SilverStone SX1000‑LPT belongs to SilverStone’s SFX‑L “SX‑LPT” Platinum family. It targeted enthusiasts needing ATX‑class power in small‑form‑factor builds. This is an enthusiast‑tier, fully modular 1000 W, 80 PLUS Platinum SFX‑L unit built around a single 12 V rail and Japanese capacitors, with semi‑fanless 120 mm cooling and a 50 °C continuous rating. It exists to power high‑end GPUs and dense SFF systems without moving up to ATX size. A 5‑year manufacturer warranty backs it. Notably, it was the first 1000 W SFX‑L PSU available. Discontinuation has not been officially indicated.
