Yes I would think so. According to my research they only use 110W each those cards. And needs 1 8pin and 1 6pin PCI-E connector, so you would have to use molex adapters. But it should definitely be able to provide enough power.
On the newegg page: http://www.newegg.com/product/product.aspx?item=n82e168... it says 1 x 6-Pin, 1 x 6+2-Pin. If your PSU is different then I don't know what's going on.
