i5 2500k

8 GB Ram

AMD Radeon 6870

1 TB HDD

is a 600-650 good enough or will I need a 700?

I run on a 550W on the same setup, 600 will be more than enough

The minimum for that card is a 550W Power supply. Make sure you buy a good branded PSU such as Corsair or Antec and do not buy a crappy $20 as they are more likely to blow up instead.

My friend bought a el cheapo PSU and within 3 days it actually blew up and took his hard drive and graphics card with it.......

Thanks for the Feed back, what exact power supply do you have?

I have a Corsair Builder Series CX600 V2 (600W). It's good for the price however it emits a very high frequency noise both when the PC is on and off. Doesn't bother me but just a word of advice before building a silent setup :)

I plan on buying the Corsair gaming series 600-Watt ATX CPU power supply. And one more question, Is installing a new power supply as simple as just taking off the cover of your case, unplugging all the cords from the power supply to motherboard etc, and replacing it with the new power supply?

Usually Yes....

Cable management can often be a pain though.

I am going to have install a new one, I hope, if the cords are easy to set up, I should be good right?

The minimum is 500W, but actually, my friend ran a similar system on 430W.

I honestly can't think of any reason why you would have any problems......

Good PSU choice btw.

@Neo, It's always better to buy the highest wattage you can as it will save you money in the long run when you want to upgrade.

Thanks for the feedback guys. I watched alot of youtube videos on PSU installation so I hope everything goes good.

Haha sorry guys, here is my full build specs, now I am going to buy a 600 watt PSU power supply tuesday, are you positive it is good enough for this...

- Cooler Master HAF 912 Mid-Tower Gaming Case w/ Adjustable HDD Cage

- Intel® Core

Are you using one Radon HD 6870 or two in crossfire? If you are using the former, 600W is enough, but if you are using CrossFireX, then you'll need a higher PSU wattage.
