I'd grab a Seasonic Platinum 860W just for good measure and future headroom for upgrades.

Here are 2 online calculators I used to determine PSU capacity / sizing. Might answer your question:

Asus PSU Calc (http://support.asus.com/PowerSupply.aspx?SLanguage=en)

CoolerMaster PSU Calc (http://www.coolermaster.outervision.com/)
