## Long description

The Seasonic VERTEX GX-1200 is a 1200 W power supply unit designed for modern PCs, certified 80 PLUS Gold for high efficiency and supporting ATX 3.0 and PCIe 5.0 (12VHPWR) standards. It provides stable power delivery through a 20+4 pin ATX motherboard connector and multiple peripheral cables, and features a 135 mm fluid dynamic bearing fan with hybrid fan control for reduced noise and improved longevity.
Advantages
The VERTEX GX-1200 offers up to 90% efficiency at typical loads thanks to its 80 PLUS Gold certification, reducing wasted energy and heat. Native support for ATX 3.0 and the 16‑pin PCIe Gen5 (12VHPWR) connector ensures compatibility with current high-end GPUs and motherboards. The unit uses a premium fluid dynamic bearing (FDB) fan and Seasonic’s hybrid fan control to minimize acoustic output and extend fan lifespan. Compact cable lengths and a black finish facilitate clean system builds.
