be quiet! Straight Power 12 Spec and Price in the United States
Straight Power 12 sits below Dark Power in be quiet!'s range but keeps the acoustics: an 80 PLUS Platinum unit rated up to 93.9%, cooled by a 135mm Silent Wings fan behind a funnel-shaped inlet. Full-bridge LLC topology and a single high-current 12V rail keep regulation tight, and it is ATX 3.1 compliant with support for PCIe 5.1 cards. Modular cabling and a ten-year warranty. Choose it over Dark Power when the overclocking key and the titanium badge are not worth the difference.
