Unboxing Vertex GX-1200 (2024) | ATX 3.1 and 16-Pin PCIe Gen 5.1 Cable (12V-2x6)

Seasonic's latest VERTEX ATX 3 Series is designed and built to power new PC components requiring the new ATX 3.1 and PCIe 5.1 standards.

Micro Tolerance Load Regulation

Seasonic's latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.

Digital Hybrid Fan Control

Seasonic's vast experience in designing the most silent and efficient power supplies on the market was translated into the development of Hybrid Mode; a state-of-the-art digital fan control that enables users to keep the overall fan noise at the lowest possible level.

Note: The Digital Hybrid Fan Control chart is provided for reference only. The shape of the curve can look different due to the variability in ambient temperature, system set-up, air flow, and other unpredictable factors.

  • Reduced noise without increase in temperature
  • Extended fan life due to the reduced number of fan rotations
  • Optimized heat dissipation at all times
  • Unsurpassed silent performance in Fanless Mode

Fluid Dynamic Fan Bearing

High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.

When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces.

As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
