Seasonic Vertex PX-850 850W - PSU, 80 Plus Platinum

The Seasonic VERTEX PX-850 is a fully modular power supply designed for high-performance PC builds. It delivers a continuous power output of 850 watts and operates with an 80 PLUS Platinum certification, achieving up to 92% efficiency at typical workloads. This unit complies with the ATX 3.1 standard and includes a native 16-pin 12VHPWR PCIe connector, providing direct power to current-generation graphics cards without requiring an adapter. The fully modular design allows for the use of only necessary cables, which assists with internal airflow and cable management.
