Seasonic VERTEX GX-1200 is a high-end, energy-efficient PC power supply. This ATX 3.0 power supply with a 16-pin 12VHPWR connector for graphics cards is ideal for the latest generation PCs. Cooling is provided by a silent 135 mm fan.
High-performance Dynamic Bearing (FDB) fans are designed to take advantage of the impact-absorbing effects of oil. They are extremely reliable and generate much less operating noise and heat than ball-bearing fans. Lubrication of the bearing surface reduces friction and vibration and, consequently, overall energy consumption. Thanks to effortless, quieter rotation and robust construction, this reliable fan technology also significantly increases fan life.
As the fan shaft rotates, high-pressure oil drifts along the grooves in the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, the dynamic pressure of the oil also increases and the shaft is lifted out of the bearing to create smooth, effortless rotations. The chevron shape of the grooves effectively channels the lubricant and prevents leakage.
The Vertex GX series achieves 80 PLUS Gold certification with 90% efficiency at 50% system load.
Seasonic 's ongoing commitment to the development of quality analogue power supplies has resulted in ripple levels well below the average industry standard of 20mV. Seasonic engineers have implemented a new internal design where, instead of cables, the rear panel and PCB (Printed Circuit Board) are connected by a copper plate. This advance not only reduces the chances of production errors during manual manufacturing phases, but also improves the quality of output voltages.

Need a faster, 12VHPWR compatible power supply for my new G¨PU (and future ones?). Seasonic still remains my brand of choice for quality and compliance.
Completely modular, it's perfect for cable management. After monitoring voltages over several weeks it's stable.
The 12VHPWR cable supplied supports 600w to power my RTX 4080 Super and is much more reassuring than the decouplers we saw at the beginning.
