My setup is at the bottom. I don't really like the PSU I have now. I bought it just about three years ago with the intent of upgrading it later. I want to get a second 5770 soon, no other reason than I want to run more enthusiastic settings on my games, and I'd really like to upgrade my PSU at the same time. Now I'm seeing a lot of different PSUs and the more research I do, the more questions I end up with then answers. So here's the parameters I want/need: 550-700 Watts, modular, 80 Plus Bronze certified, something name brand, and can support up to three video cards.
I'm adding only a second card, but down the line I may want a third. Here are some I've been looking at. I just dont know if the little things are right. Like, do I want one or multiple 12V rails, is there enough PCIe power cables, on and on. Thoughts?

BTW, that Corsair Professional PSU is probably my front runner. It's a bit expensive for my taste, I was planning on spending 100 or less on this PSU. But it's everything I want, I just want to know if it's what I need!
