I've seen a lot of graphic card benchmarks ( which include the geforce 8 ) , but I guess I missed this one- http://www.anandtech.com/video/showd...x?i=2870&p=18.
Noted in the bench mark when they used 2 geforce 8s in Sli mode, they recommended 30A on the +12V rail. When I check out the specifications of power supplies with say 2 rails, the +12V1 and +12V2, is it appropriate to add the amps of these rails up to get the total amps?
Also do the number of rails matter either? Cause I'm starting to see a lot of power supplies with 4 rails. Is it better to get a power supply with 2 rails which equal the same amps as a power supply with 4 rails which add up to the same number of amps?
