X-bit Labs has published another PSU roundup, this time they looked at some models from AcBel, Corsair, Gigabyte and Zalman.
Today I will be discussing seven power supply units which wattage is now considered medium, from 450W to 850W to be exact. Well, this positioning is not exactly accurate. Although most of the manufacturers have already released their 1000W PSUs and some of them have reached 1500W, even very advanced PC configurations with a top-end CPU and a couple of graphics cards consume much less than 1000W. A typical home system with a dual-core CPU and one graphics card will find even a 600W PSU somewhat redundant.
