The only recommendation I will make is getting a corsair single rail power supply. No matter what you do make sure that you follow this one single piece of advise because I can assure you that you will not regret it.
I have been through numerous "high end" high wattage multi-rail power supplies. I finally got a corsair 850w single rail unit. This power supply came with a 5 year warranty and if they are willing to warranty something like a PSU for 5 years you know it must be built like a tank because they really hate replacing defective units.
Not only that but I was impressed by the overall quality surrounding this particular unit. It came in a black velvet bag with the corsair logo on the front. It also came with a really sturdy and sharp looking case badge for the front of my case.
I bought this unit because I originally had a xion 650w unit that went after 6 months it was 4 rails. Newegg replaced it for free with a new xion 650w with 6 rails and modular cables. Awesome free upgrade right? Well 7 months later I was sending that unit back to the manufacturer and I got jerked around by them for about 3 months before finally getting a new unit back which was an 850w 6 rail unit with modular cables. I did not use that unit I sold it because it was a refurbished unit and I had already got tired of waiting so I bought the corsair so I could use my computer again.
In short it was a bad experience with that company on many levels. But now that I have a corsair single rail unit my trouble has ended.
The xion units were not the only ones I have had trouble with though.
The biggest issue with the multi-rail units is that you have to use all of the rails to keep from tearing it to pieces. If you try to attach to many devices on the same cable you fry the rail out and then you have to replace the unit. The power distribution in a multi-rail unit is crap.
If you buy a single rail unit you can safely attach anything and everything in your case because that one single rail was built to handle the entire load the unit was built to take. No guessing about how much each cable set can handle before it stresses a rail and kills it.
So that is my piece of advise when building your machine and I hope it helps you out. I hate to see people suffer from poor power supplies because that is an important piece of the system to consider.
