Instead of trusting its favorite manufacturer, FSP, be quiet! trusted CWT for its new flagship PSU line. The Dark Power Pro models utilize a new platform with good build quality and high-performance levels in all areas, while at the same time manages to keep noise output low.
Nonetheless, we have a feeling that CWT should use a more advanced design. Yes, there is digital control for the APFC converter, the primary side, and the 12V circuit. Still, there is no bridgeless design that the much older EVGA 1600 T2 utilizes, or the super high-end bridgeless totem-pole PFC converter that both the Corsair AX1600i and the Wentai Aidan T1616 use. If you want to go after products like the ones mentioned above, you have to try hard. You have to use cutting edge technology, and not just a traditional recipe which might still work well, but it cannot threaten today's top-performing units in this high wattage category.
There is no doubt that the be quiet! Dark Power Pro 12 1500W should be on your short list if you want to combine a pair of RTX 3090s with a power-hungry AMD Threadripper CPU. It has the power to support all parts mentioned above while keeping noise output low.
If you are after the best performance possible, you should take a look at the Corsair AX1600i, which costs a bit more but also features control and monitoring capabilities through Corsair's iCUE suite. On the other hand, if you want even more power you should grab an EVGA 1600 T2 if you find any available. It has a lower overall performance than the Dark Power Pro 12 1500W, but it is bulletproof and can deliver huge amounts of power, much higher than its advertised levels, even under high ambient temperatures.
