  1. Grab a 750watt psu to ensure a good supply of voltage (your rig draws close to 500watts on max output)

    and yes the Hyper 212Evo will fit

    Actually, it draws 750 watts. Upon seeing this, get this power supply instead; http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108

    where do you see that it draws 750?

    I did a psu calc at 90% load resulted at 484watt

    PC parts picker estimates 541watt
  3. CX Series CX750M 750 Watt ATX Modular Power Supply or ZT Series 750 Watt Modular ATX Power Supply?

    Radeon HD 7870 - On your average system the cards require you to have a 550 Watt power supply unit as minimum and 700 Watt if you go with two cards in Crossfire mode.

    If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina. Source: http://www.guru3d.com/articles_pages/gigabyte_radeon_hd_7870_oc_review,7.html
