The Seasonic VERTEX PX-1200 is an ATX power supply unit that provides 1200W of continuous power for high-performance computing systems. It adheres to the 80 PLUS Platinum standard, delivering high efficiency to minimize wasted heat and energy consumption. The unit is built to comply with the latest ATX 3.1 and PCIe 5.1 specifications, ensuring full compatibility with current and next-generation components. It includes a native 12V-2x6 cable to directly support modern high-power graphics cards without the need for adapters.
This power supply features a fully modular design, allowing builders to connect only the necessary cables for a cleaner build and improved internal airflow. Cooling is managed by a 135 mm Fluid Dynamic Bearing (FDB) fan, which is engineered for longevity and low-noise performance. The integrated Seasonic Hybrid Silent Fan Control system allows the fan to remain inactive at lower loads, contributing to a reduced overall system noise profile. A comprehensive suite of protection features, including Over Power and Over Voltage Protection, is built-in to safeguard components.
