Product information

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

Key specifications

  • Total power: 1200 W
  • 80 PLUS certification: 80 PLUS Gold (≈90% efficiency at 50% load)
  • Motherboard connector: 20+4 pin ATX
  • Fan diameter: 135 mm (active cooling)
  • AC input: 100–240 V, 50–60 Hz
  • Product colour: Black

How to use

Install the VERTEX GX-1200 into a compatible ATX chassis, connect the 20+4 pin ATX cable to the motherboard and attach the required PCIe power connectors, including the 16‑pin (12VHPWR) for compatible GPUs. Connect SATA and peripheral cables as needed. Ensure mains input matches the specified 100–240 V, secure all cables, and power on the system. The hybrid fan control will manage the 135 mm fan automatically based on load and temperature.

Usage recommendations

For stable operation, use appropriate cable routing to maintain airflow in the case and verify that your GPU and other components are compatible with the 16‑pin PCIe (12VHPWR) connector. Regular dust cleaning of the fan and vents will help preserve cooling efficiency and extend service life.
