Well, I'm worried about how much power my system will use. So, I thought I'd ask your opinions on it. Here's my rig:

Corsair C70 Arctic White (case)
Corsair Vengeance 8GB 1600mhz (RAM)
ASRock Extreme4 Z77 (motherboard)
MSI R7970 Lightning 3GB (graphics card)
Intel i5 3570K (cpu)
Cooler Master Hyper 212 Evo (cpu cooler)
Western Digital Blue 1TB (hard drive)
ASUS 24xDVD-RW (optical drive)
And 3 chassis fans, with 2 cpu fans

So, as you can see, I'm stumped. I don't know what I should buy. I was think in the 750 - 850 Watt range, since I plan on going crossfire eventually. Thanks in advance.

For a system using two Radeon HD 7970 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 750 Watt or greater power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 58 Amps or greater and have at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

Well, thank you sir. But do you have any suggestions for it? That's the area of wattage I was already aiming for, so maybe like an 850 watt PSU?

A high quality 850 Watt PSU would give you some spare capacity to handle overclocking.
