So I bought 2x MSI gtx 560 ti hawk editions which arrived today. However I'm a little concerned whether or not my power supply will be sufficient enough for them plus the rest of my PC. I will not be overclocking these videos cards. To save some time my Powersupply is 750w and has 25amp on each of the four 12v rails.
1x 7200rpm 1tb HDD
1x 7200rpm 500gb/4gb HDD/SSD hybrid drive
3x 200mm red LED fans
1x 140mm fan
1x 120mm fan
1x fan controller with LCD display
1x dvd-rw optical drive
Need an answer asap so I know whether or not to return my power supply now and get a higher wattage.
