The be quiet! Pure Power 13 M is a fully modular power supply designed to provide stable energy for modern PC builds. It delivers 750W of continuous power and adheres to the ATX 3.1 standard, ensuring compatibility with the latest hardware. Its 80 PLUS Gold efficiency, reaching up to 94.3%, helps reduce energy waste and heat during operation. To keep your system quiet, it uses a 120mm rifle-bearing fan with a semi-passive Zero-RPM mode, meaning the fan stays off during light loads to eliminate noise entirely. Inside the black chassis measuring 160 x 150 x 86 mm, the unit employs an LLC + SR + DC/DC topology for consistent voltage regulation. You can customize your cable management using the included sleeved and flat cables, which connect to a variety of ports including a 12V-2x6 PCIe 5.1 connector for high-performance graphics cards. With a wide range of protections like OTP and OVP, this unit is a reliable choice for users who want a silent, efficient power source for their gaming or workstation setup.
