The coil whine from this was very loud, unacceptable for the price, but after I returned it I was told there were no issues and it was "within tolerance".I still got a refund and went for the Vertex Prime instead. Runs completely silent. I highly recommend the Prime for no surprises.

Seasonic does it again! Extremely well-performing power supply, with a quality that is felt as soon as you take it out of the package. Feels very well built. It's expensive yes, but you get what you pay for. Seasonic is in a class by itself.The only thing I think is a bit like "that" are actually the cables. Good lengths and such, but everyone thinks they are a little too stiff. It can be a bit of a pain to get it looking good. But otherwise, I only have good experiences with this grudge (and Seasonic in general)

Seasonic Vertex ATX 3.0 80 Plus Gold 850W Power Supply
Fully compatible with ATX 3.0 and PCIe 5.0 standards Full modularity for the best cable management options Added 12VHPWR cable to comply with the new graphic cards 135Mm fluid dynamic bearing fan for quiet operation Seasonic hybrid silent fan control for optimal cooling The new Vertex Series units will provide 850 Watts of true power in Gold levels of efficiency with all the best features you can expect from a Seasonic power supply. The Vertex GX Series achieves 80 PLUS Gold certification with its 90 percent efficiency at 50 percent system load. Seasonics latest Vertex Series is designed and built to power new PC components requiring the new ATX 3.0 and PCIe 5.0 standards. Seasonics 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 fan control that enables users to keep the overall fan noise at the lowest possible level. High performance fluid dynamic bearing 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. Fully compatible with ATX 3.0 and PCIe 5.0 standards, full modularity for the best cable management options. Added 12VHPWR cable to comply with the new graphic cards, 135 mm fluid dynamic bearing fan for quiet operation. Seasonic hybrid silent fan control for optimal cooling.
