Powerful PCs need a steady, silent heart - without one you risk overheating, noise, and wasted electricity. The be quiet! Straight Power 12, 1200 W, 110 - 240V, 50/60Hz, 15/7.5A, Power Supply delivers rock-solid, ultra-quiet power to keep high-end rigs cool, efficient and ready for the next generation of components.
be quiet! Straight Power 12, 1200 W, 110 - 240V, 50/60Hz, 15/7.5A, Power Supply - the quiet solution for demanding builds
Modern gaming and workstation PCs push power limits, often causing noisy fans and unstable voltages. Unstable power can lead to crashes, reduced component lifespan and a noisy workspace. This PSU solves those issues with ATX 3.0 compliance, 80 PLUS Platinum efficiency and a Silent Wings fan that runs almost unheard. You get a clean, reliable power source that lets you focus on performance, not on cooling or electricity bills.
