Do you want a modular powersupply? I can say that the best brands for a powersupply right now would be from Corsair, Seasonic, XFX, Silverstone and Antec. My personal preference would be powersupplies from Corsair and Seasonic. Because you can never go wrong picking them and the sleeving is black I can't even see the colours of the wires. (In Corsair's case even the wires are black so its pretty hard to Identify them inside the sleeving.) But I estimate you should be fine with a 550-650watts for your rig and if you don't plan on adding a second Graphics Card. Otherwise if you plan on CFX with those I estimate 750-850watts.
Don't skimp on the PSU it may be tempting to get that $100 850W PSU you see but it's not worth it. Quality is what you want here since it supplies the life blood of your system. A 650W from Corsair, Seasonic, or XFX should be enough to put you in optimal power efficiency when under 100% load. The 80+ power ratings do matter. Basically the lower 80+ ratings (Bronze) waste more energy converting from 120V AC power to the DC power and voltages you need. This wasted energy is converted to heat. So if you get an 80+Gold PSU it will use less energy and produce less heat. Should you get an 80+gold PSU? Probably not, 80+ gold is only suitable for those very energy conscious or if you're going to be running your system at 100% load 24/7(like a dedicated folding rig). Extra cables to buy? You shouldn't have to buy any extra cables with a PSU since usually PSUs have enough cables for what they are rated to power for example a 750W PSU can power 2 GPUs and therefore has 4 PCIe power connectors. However, sometimes if you're in a large case you may need to get extensions for some connections to do nice tidy cable management. Different models in the top brands usually don't have many differentiating features the most noted ones are modular vs non-modular and warranty length.
you would go with corsair 600W but i would get 850W just for extra power for overclocking and crossfire
buy a 650w seasonic, corsair, xfx, or antec and you'll be good to go.
