make sure with the mb that the mb has the bios update for the newer cpu. some of them need it for ib cpu. dont forget to toss in a 17.00 dvd burner/reader. without it you have to install windows and your program from a usb stick. theree are a few good power supply wattage web pages. http://www.extreme.outervision.com/psucalculatorlite.js... http://www.thermaltake.outervision.com/ http://support.asus.com/powersupply.aspx
when you look at power supply pick one up with one main rail on the 12v line. you want to look at the wattage of the 12v line and make sure the wattage or amp rating is larger then your load. so if your cpu is 77w and your gpu is 250w. the min you would be looking is 327w on the 12v line with 27 amp rating. with power supplys your better off buying a unit that 100w larger then your needs. also when buying a power supply stay away from low price no named units.most of them that have been tested on hard cops forum cant output there rated load.
