I don't know much about computer hardware but I want to upgrade my PSU and possibly even throw in a second Radeon HD 6850 in crossfire and a better CPU. I tried using a power supply calculator online but I couldn't really figure it out.
Intel I7 2600
1 Disk Drive
1 1TB Hardrive
6 USB Spots all but one being used
Does anybody have any suggestions for a better PSU or do I need to put more information. Any help would be appreciated.
