Really great if you're running high end parts.

When it comes to Power Supplies, never be stingy and spend a good amount on a solid one. Corsair is one of the most well known PSU companies and their supplies are up top in terms of qualities and specs. When it comes to buying a power supply it is important to remember that two things are needed:
1. Enough watts, look up the total watts of everything you own and buy a power supply that is at least 100w more so as to give you enough headroom for upgrades or overclocking if thats your cookie.
2. Enough Amperage. This is veryyy important. The +12v rail is whats important as most modern cards require a minimum of 25A on a single rail. Dual rails are also nice if they are each at 25. For example, my XFX DD Black edition Radeon HD 7970 will not run on my old psu. It was a solid Rosewill 600w psu which had more than enough watts to run it, however, the thing maxed at 35A on both rails together. The minimum needed for the card was 36. This PSU, has 750w and the following ratings on each charge: +3.3V@25A, +5V@25A, +12V@62A, -12V@0.8A, +5VSB@3A.
+12v@62A is excellent for the card now. This also gives me headroom if any future parts require more Amperage or watts. The price is seriously perfect here on Amazon. The power supply retails for 100 bucks on other sites.
-pci express power at 62A (+12v)
-sleeved components with the cables reaching full tower( they arent short cables so it works on an NZXT Phantom and an Antec twelve hundred tower.) Both of which are full towers.
-active APF correction
-80 plus bronze (Not found often at this price point level with this amount of watts)
-750W (More than enough for sli gtx 660's) or in my case, still more than enough for my xfx overclocked 7970, 9 fans, 2 hard drives, fan controller, card reader, blu ray drive, dvd burner, 8gb ram, overclocked cpu and bigger more powerful cpu fan.
-a nice big fan
-its not modular, but at this price, who cares?aha.
EDIT: OCTOBER 11th 2012-The first one arrived with a definite loud buzzing so I had to exchange it. It happens with mass electronics and typically just bad luck. Corsair was good about it and the new unit was perfect.
DO NOT get stingy when it comes to power supplies. If a 850w power supply is selling for 50 dollars from a random company, you will put your other parts at risk. This one offers Over-voltage and over-power protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components.
It is also rated at 80 plus BRONZE. Which is excellent for the price. At this price range you mainly see psu's with just 80 plus certification. This one is one step higher.
Lastly, the card offers 0.99 Active Power Factor Correction provides clean and reliable power. (APF) for short. Another thing that is not found at this price range.
Top this with a 3 year warranty and bam, solid computer.
Don't let a cheap power supply kill your whole system, with this excellent brand, only the power supply will die if it eventually happens. A cheap psu will more than likely take it, along with all your expensive components.

FOLLOW UP EDIT December 2nd 2013: ***Sorry for the wrong date here. I meant December 2nd****
The power supply is still going very strong. The system it is now powering involves additional lights, watercooling, another drive, and a max overclock on the card. The cable sleeving on the 24 pin board power has become rigid and a ripping in areas. However, with a few cable ties it isn't so bad.
