be quiet! Straight Power 12 1000W Platinum

The Straight Power 12 1000W is a near-inaudible Platinum-rated unit with native 12V-2x6, full modularity and 93.9% peak efficiency, a capable pro-tier PSU. It's well suited to high-power, quiet-focused builds wanting Platinum efficiency and current-gen GPU connectors. Value-first buyers can save meaningfully by dropping to a Gold-rated 1000W instead, where the efficiency gap rarely pays back.
