Seasonic and Noctua launch PRIME TX-1600W power supply: runs without fans at 800W power usage

Seasonic and Noctua have been cooking behind the scenes, but now they're introducing the new PRIME TX-1600W power supply: a new ultra-quiet beasty 1600W PSU with dual 12V-2x6 power connectors ready for multiple next-generation GeForce RTX 5090 graphics cards. Check it out:

The new collaboration between the two companies delivers something truly special for high-end desktop PCs, with Austrian-based Noctua known for its leading cooling technology and uber-quiet fans, with the new PRIME TX-1600W PSU featuring NF-A12x25 fans which have ultra-quiet operation.

1600W of power is a lot, with the new PRIME TX-1600W PSU supporting both ATX 3.1 and PCIe 5.1, with dual 12V-2x6 power connectors that are ready for multiple high-end GPUs. Noctua says that the new 1600W power supply is designed to work in full passively-cooled mode at below 50% load and under 25C.

This means that if you're using 800W or less power in your system -- let's say a higher-end AMD Ryzen 9 9800X3D processor (or even an Intel Core Ultra 9 285K) and NVIDIA's current-gen GeForce RTX 4090 (or even the next-gen RTX 5090) then the PRIME TX-1600W power supply will run passively... no fans running at all. Very cool to see.
