PSU power question 850 watt

[deadalewives]

Hi guys. I'm planning on buying a new PC soon and I'm curious both about how MUCH power my parts will be using and if I'll have more than enough available power from my future PSU. I'm especially curious about how much energy the GPU uses. Also, I'm curious if I'll have enough power in the event that I ever want to crossfire two video cards in the future. Here's what I'm getting:

PSU: Raidmax RX-850A, 850 Watt
CPU: AMD FX-6350
GPU: Sapphire Dual-X R9 280x
RAM: 8GB DDR3
HDD: 2TB
Heatsink: Arctic Freezer A11
MoBo (if this matters): GIGABYTE GA-970A-UD3P

Oh yeah, and a DVD RW as well.

Even a good 750w is more than enough for 2 r9 280x.

Raidmax is a tier5 PSU.

"Tier Five - Replace immediately. These units are NOT recommended for any system, no matter the purpose. Reference to higher tiered models for a better and potentially money-saving unit"

Thanks for the help guys. Soon after I posted this question, I discovered pcpartpicker.com. This is very informative. I suppose 850 watts would be a bit of a waste. Heh.

Let's say 750watt then. What's a good brand you guys would recommend?

All right, I'm going with this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438027
EVGA Supernova 750. I like that it's modular, and it's 80+ gold rating helps too.

Tier2, class b PSU. Good choice.
