And will a corsair enthusiast 850w be able to handle two r9 280Xs?

Hey there Roiri100,
The CM Storm Enforcer can fit graphics cards up to 270mm with the HDD cage and 390mm without the cage. You can hit up the specs listed at http://www.coolermaster-usa.com/product.php?product_id=3038

As long as the R9 cards you're getting have PCIe power plugs on the top instead of the side, you should just barely be good
