If you want a good 850W the corsair HX850 or AX850 is very good as well as the XFX 850W
^this.

If both GTX580s and the i7 2600k are to be heavily overclocked, I would recommend getting a 1000W (eg Corsair HX1000).

56 amps on the 12v Rail is more than enough for SLI GTX 580's

That PSU is fail man.... Quote from hardwaresecrets review of it

Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components.

I usually recommend a quality 750W for SLI GTX580s, and yes that includes overclocking of all major components.

What you get depends on budget, but you have to pay a minimum of about $100 to get a decent 750W.

yeah, I am looking for a power supply for a single gtx 580 system. I will be overclocking the cpu and the msi lightning I mentioned earler comes overclocked from the factory. So, I guess I am getting an over all concensis on a 650 watt unit. I appreciate all the feedback

Particularly if you're not overclocking the GTX 580 more than the factory OC, I'd feel comfortable with an overclocked i7-2600k and GTX 580 on a good 520W power supply. 650W is okay but unnecessary.

Check the below (note where it says system power consumption and where it doesn't, and keep in mind that you won't reach full synthetic loads in any real usage scenario):
http://www.xbitlabs.com/articles/cpu..._12.html#sect0
http://www.xbitlabs.com/articles/vid...0_5.html#sect0

A decent power supply would be an Antec High Current Gamer 520W (Seasonic S12II Bronze build) for $60:

Granted, a lot of the higher-quality 650W units are better than the HCG 520W in ways other than having a higher wattage. They're more expensive from having superior, more costly designs that perform better.
