LatiosXT is correct. That PSU barely meets the minimum power supply requirements for the videocard. ASUS has a wonderful PSU calculator at its support site: http://support.asus.com/powersupply.aspx
. While I don't know how many fans your case has, I assume you have at least one DVD-RW drive in this system, so your recommended PSU wattage for the system as it is currently configured should be at least 850 watts. So if Amazon can't come through for you, cancel the order and start looking at NewEgg instead. It should be noted that NewEgg does not have your desired 1300-watt PSU in stock at this time, either, so you can have them "auto-notify" you when they do get it in stock again, or you can try buying this one: http://www.newegg.com/Product/Product.a ... 6817182239
. Granted, it is rated at only 1000 watts, but it should be sufficient for what you are using. Just a suggestion.
