I don't quite understand how this whole amps and rails things works and I need a little bit of help. I've had a GTX 285 for a while now and I just recently ordered another one as an upgrade that I can run in SLI. However, my 800w power supply (http://www.amazon.com/Power-4-pin-Power-Supply-Black/dp...) seems to lack the addition 2 6-pin cables I need to power my second card... So I also purchased two 4 to 6-pin adapters. My question is simply "Will I be able to run these cards in SLI with my current power supply and those adapters?
