Hiya I'm looking to upgrade my pc near christmas time to two 670's I currently have a non modular PSU being the Corsair TX650 which I know with a lot of adapters will power two 670's just about. However I may as well get a Higher wattage psu to be safe which one would you recommend, need 3 power connectors for my HDD, SSD, and Optical drive, 24 Pin, 8 pin for motherboard, 2 8 pins, 2 6 pins. Any suggestions 
Thanks

Thanks
