It seems hard to imagine that a PSU that provides more than a kilowatt of power can be considered quiet but Cooler Master goes even further with their Silent Pro Hybrid 1300 Watt PSU.  Rated for 80 Plus Gold and able to provide 1260W @ 105A on its single 12V rail this beast of a PSU and its eight 6+2 pin PCIe power connectors should be able to power any graphics system you might want to dream of setting up.  Part of the Silent comes from a unique fanless mode, when load is under 200 watts and the temperature below 25C the fan powers off.  The other modes are manual and auto, which anyone with a recent video card will be familiar with.  From the 5 year warranty to the solid power that this PSU provides, Hi Tech Legion found a lot of things to like about this premium PSU.
 

"With the Silent Pro Hybrid 1300 Watt PSU, Cooler Master has actually added usability features to a category typically limited to simply watts and amps. The Cooler Master Silent Pro Hybrid 1300 Watt PSU goes beyond being an 80+ Gold, 105A single 12V rail behemoth, and incorporates a 7V chassis fan rail along with a 5.25” Dual Fan Control Module. After all, if you have need for 1300 watts of power, odds are good you are going to have more than a fan or two running in your case, and what better place to power and control them from than directly from the PSU? In addition to a single-channel, continuously variable controller for up to three chassis fans, the fan control module offers PSU fan control in addition to “PSU Fanless Mode”."
