Product information

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.

Suitable for

  • High-performance gaming PCs with modern GPUs requiring PCIe Gen5 power
  • Workstations and content-creation rigs needing stable 1200 W power delivery
  • System builds prioritizing quiet operation and long-term reliability

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, fluid dynamic bearing (FDB)
  • Supports ATX 3.0 and 16‑pin PCIe Gen5 (12VHPWR)
  • Input voltage/frequency: 100–240 V, 50–60 Hz
  • Colour: Black

How to use

Install the Seasonic VERTEX GX-1200 into a compatible ATX case following the motherboard and case manufacturer’s instructions. Connect the 20+4 pin ATX power connector to the motherboard, attach PCIe 16‑pin (12VHPWR) or other required PCIe/CPU/SATA cables to components, and ensure all connectors are fully seated. Verify input voltage range on your outlet (100–240 V) before powering on. The hybrid fan control manages cooling automatically; no manual fan adjustment is required for normal operation.

Usage recommendations

For reliable performance, use appropriate cable routing to avoid strain on connectors and maintain clear airflow around the 135 mm fan. Match the PSU capacity to system requirements — the 1200 W rating suits high-end GPUs and multi-drive configurations. Ensure compatible chassis space and connector support for ATX 3.0 and 12VHPWR when planning upgrades.
