The be quiet! Straight Power 11 1000W is a premium fully modular power supply designed for silent operation without compromising on power delivery. Featuring the renowned SilentWings 3 135mm fan with advanced fluid-dynamic bearing and 6-pole motor, this PSU operates virtually inaudibly while maintaining excellent thermal performance. The wire-free internal design optimizes airflow through the chassis, reducing internal temperatures and allowing the fan to spin slower under load for even quieter operation.

Certified with 80 Plus Gold efficiency (up to 93% at 230V), the Straight Power 11 delivers exceptional power delivery with minimal heat generation and energy waste. It features four independent +12V rails (two at 30A, two at 22A) for stable multi-GPU support, comprehensive protection circuits (OCP, OVP, UVP, SCP, OTP, OPP), and Japanese 105°C-rated capacitors for long-term reliability. The fully modular cable system provides maximum build flexibility, while the compact form factor (170x150x86mm) fits most modern PC cases.

This power supply is fully compatible with ATX12V v2.51 and EPS 2.92 standards, making it suitable for current and future motherboards. With a 5-year manufacturer warranty and MTBF rating of 100,000 hours, the Straight Power 11 1000W represents a solid investment for builders seeking quiet, efficient, and reliable power delivery.
