Be Quiet! Straight Power 12 1000W ATX Power Supply 80 Plus Platinum

Be Quiet! Straight Power 12 is a 1000-watt fully modular ATX power supply unit certified at 80 Plus Platinum efficiency — the second-highest efficiency tier available. It is positioned as a premium PSU for enthusiast builders who demand the highest power quality, lowest noise, and maximum energy efficiency.

The 80 Plus Platinum certification ensures at least 92% energy efficiency at 50% load, translating to lower electricity consumption, reduced heat output, and quieter operation compared to Gold-rated alternatives. Fully modular cabling with individually sleeved connectors provides a clean installation experience. ATX 3.1 compliance and dual 12VHPWR/12V-2x6 connectors ensure compatibility with current and next-generation high-power graphics cards from both NVIDIA and AMD.

The PSU utilises a virtually inaudible 135 mm fan with fluid dynamic bearing and a semi-passive mode that stops the fan entirely at low loads. Japanese capacitors rated for continuous operation at 105°C ensure long-term reliability. Full protection suite includes OVP, UVP, SCP, OCP, OTP, and OPP. Dimensions are 150 x 86 x 170 mm. Backed by a 10-year manufacturer warranty.
