Does anyone know if this Thermaltake PSU is a decent one?

I'm looking at parts for a new build. Newegg has a Thermaltake Black Widow 850W PSU for a decent price, but I can't find a whole lot of information about it. I've read some of the other Thermaltake power supplies are good. This is specifically decribed as Thermaltake Black Widow W0319RU 850W ATX 12V v2.3, EPS 12V v2.91 CrossFire Certified 80 PLUS BRONZE Certified Modular Active PFC Power Supply. The link is www.newegg.com/Product/Product.aspx?Item=N82E16817153106. The build I'm looking at is an i7 LGA 3820 or i7 3770 with a AMD 7870 or 7950 graphis card. Any information would be appreciated.

For that price you can get better units, also you don't 850W, even for two 7950, a 750W psu will do, here's some quality psus for less :

Also if that build is mainly for gaming, i recommend the i5-3570k instead and a z77 motherboard, if it's for editing/3d modelling, get the i7-3770k and the z77 motherboard.
The hyper threading of the i7 won't bring any gains in gaming(expect a few cases, for worse or better) over the i5, the i7 does better in other tasks like editing/encoding/3d modelling, but for gaming the i5-3570k is the best choice, it's much more cheaper and you'll get the same performance in gaming as the i7.
You can find good z77 motherboards like the sus P8Z77-V LK, the Asrock z77 extreme 4/6, the gigabyte GA-Z77x-D3H(UD3H/UD4H).
