PC Perspective posted a review on PC Power & Cooling's new flagship power supply - the Turbo-Cool 1200W.
The Turbo-Cool 1200W power supply was not designed to be quiet; and its not. The primary design goals were to deliver stable, clean outputs with high reliability for high-end workstations and servers. To accomplish that you need good cooling, which in this case, requires a relatively high-speed fan. If you need a 1200W power supply, you will most likely be dealing with noise from numerous other component cooling solutions dissipating all that power.PC Power & Cooling Turbo-Cool 1200W PSU Review
