My setup is going to be
- i7 3820 cpu
- Asus Sabertooth X79 mobo (might get a Rampage IV Extreme if i can get a good price)
- Asus 560 ti gpu (might upgrade later on)
- 16GB Ripjaws Z Series 1600 RAM
- 4 or more Corsair AF series fans (3x120 1x140)
- Seagate Barracuda 7200 1TB HDD

I currently am planning on getting an NZXT Hale82 650W psu, because when I used a psu calculator it said the power consumption would be around 500w recommended. But, 650w personally doesn't seem like it would be enough to power this system especially if i want to upgrade my 560 to say maybe a 670. I know corsair is a higher quality psu but i am also looking to save a few bucks if i can.

A 650 watt PSU is more than enough for either card in that system. The recommended PSU (link) (unless you have some limited edition one, but that uses even more power than the 670 itself) on Nvidia's site for the 560 ti is a 500 watt. The recommended PSU (link) for the 670 (there's no ti version as far as I can tell) is the same at a 500 watt. The GPU is more powerful, but since it's a generation older, it is also more efficient meaning it uses the same amount of energy to do more work.

If the Nvidia site is correct (and brand's sites usually are, those estimations are very conservative and have large margins for safety), then you should have at least 100 watts of head room, if not more, with either card. Perfectly adequate.

And that is a fine brand imo. I am currently using a 750 watt Hale82 series NZXT PSU myself, and it is working like a champ. I purchased it for Crossfire with a 6870, which is a power hog (I believe it uses the same amount as the 670/560ti). I believe it is adequate for that need. That and I'm running 3 HDD's, 7 fans (some with LED's), OC'ed CPU (3.3 -> 3.7), and OC'ed RAM (1600 -> 1800).

So, in summary, that is adequate for your purposes.
