## Long description

The Seasonic VERTEX GX-1200 is a 1200 W power supply unit engineered for modern desktop PCs. It meets 80 PLUS Gold efficiency, delivering up to 90% efficiency at typical loads, and supports ATX 3.0 and the 16-pin PCIe Gen5 (12VHPWR) connector for compatibility with current high-end components. The unit is finished in black and includes a 135 mm active cooling fan for thermal management.
Advantages
The VERTEX GX-1200 combines high efficiency with current-standard connectivity, providing reliable 1200 W output while reducing energy loss thanks to its 80 PLUS Gold rating. Hybrid fan control keeps acoustic levels low by adjusting fan operation to load and temperature. A Fluid Dynamic Bearing (FDB) fan improves durability, lowers vibration and noise, and contributes to longer operating life compared with conventional bearing fans.
Suitable for
High-performance gaming PCs with modern GPUs using 16‑pin PCIe Gen5 (12VHPWR)
Workstations that require stable 1200 W power delivery
System builders seeking ATX 3.0-compliant power supplies
