The Seasonic Vertex PX power supply with a rated output of 1200 W belongs to the advanced segment and is aimed at building top-tier gaming PCs and workstations. The high power reserve allows you to use modern CPUs and GPUs like the GeForce RTX 4090 or 5090 without limitations, which at peak can draw up to 600 W just on the GPU power line. Compliance with the ATX 12V v3 standard guarantees support for current technologies and interfaces, including the new connectors for graphics cards.

All of the unit’s power is concentrated on the +12 V rail, ensuring high stability in power-hungry scenarios. Energy efficiency is confirmed by the 80 PLUS Platinum (efficiency up to 92%) certificate, as well as the Cybenetics Noise A rating, which indicates a low noise level even during prolonged operation. Cooling is handled by a 135 mm fan on a hydrodynamic bearing, known for reliability and long service life.

The cabling system is fully modular, allowing you to use only the necessary connections and maintain optimal airflow inside the case. The protection set includes OVP, OPP, SCP, UVP, OCP and OTP, preventing component damage during unstable mains operation or system overload. As usual for Seasonic, reliability is a priority, so the Vertex PX series comes with an extended 10-year warranty.
