Seasonic's new X-1250 PSU can provide 1250W of power, just as the name suggests, with up to 104 amps to the 12V rail which should provide enough power for even the most power hungry GPUs. Instead of going with a single rail design Seasonic chose to provide 4 rails so you should ensure to know which plugs you are using. It passed all of [H]ard|OCP's torture tests with flying colours, making it one of the better kilowatt ckas PSUs they have had the pleasure of testing and when you consider the price, with or without the rebate, it is a perfect choice for users building a system with multiple GPUs.
"Seasonic makes some of the best enthusiast computer power supplies in the world. It has long produced some of the cleanest power producing PSUs along with being some of the quietest on the market. The new fully modular X-1250 sports many enthusiast features and touts gold level efficiency. Is this new X-1250 worthy?"
