unless it is a low quality psu, you don't have to worry about providing too much power to the system. Something like the corsair cx 500w, would be good enough for the projected system. But there are many other solutions as well

you want alot more watts than recemended that way the psu runs quieter, cooler and more energy efficient get around a 750w that way you can expand in the future and make sure you get a good brand ie corsair, evga or xfx good luck :)

Your psu won't blow anything. The more, the better. If you manage to get a gold or better certificate would be very good. For your rig with the 7870, use a 600W (or greater) power supply. According to AMD website, you can go with a 500w for a single gpu, but I don't recommend it, since you leave no space for future upgrades.
