X-bit Labs has published another huge roundup, this time they checked out ten 1000W power supplies from firms like Antec, Enermax, Floston, FSP, SilverStone, Tagan, ThermalTake and Ultra.
In my last article about 1000W power supplies I wrote that a modern PC could be actually satisfied with much less power. A configuration with a quad-core CPU and a couple of top-end graphics cards would consume no more than 500W from the power supply. It is only hardcore overclockers that utilize Peltier elements or Freon compressors that may indeed require twice or thrice that amount of juice.
However, PSU manufacturers go on pumping up the capacity of their products and I now have the test results of models with a wattage rating up to 1500W. My job is to test, and it’s up to you to decide if your PC really needs that much power. I can only tell you one funny thing: the combined wattage of all the PSUs tested for this review exceeds 10 thousand watts!
From all ten models they tested only the models from Antec, Exermax, Floston and Ultra Products receive a recommendation. However, the reviewer says the Cooler Master Real Power Pro which he tested last year had better stability and lower noise levels than all power supplies he analyzed in this review.
