Product overview

Announced on March 8, 2016, the Corsair SF450 belongs to the original SF Series (80 PLUS Gold) SFX family—Corsair’s first SFX PSUs. It’s a 450 W, fully modular unit with SFX dimensions, Zero RPM fan mode, all‑Japanese 105°C capacitors, and a 7‑year warranty.

Tiered as high_end for PSUs (Gold, fully modular), it exists to power compact builds with quality components and clean cabling. It’s a strong fit for SFX/small‑form‑factor cases and mid‑range gaming rigs that don’t need ATX 3.0 or native 12VHPWR, and it also suits budget builds where efficiency and low noise matter. Notably, this was Corsair’s first SFX lineup. The Gold SF450 has since been discontinued and effectively superseded by later SF Platinum models; exact EOL timing isn’t stated.
