Compatibility of my GPU

Hey I got this GPU and two power supplies for my rig, and I'm wondering if the GPU will fry my PSU and possibly my whole system. I have these two PSU's: which one should I use?

My Rig:
CPU: Intel Core i7-3770K 3.5GHz Quad-Core Processor
Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard
Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory


GPU:
Video Card: Sapphire Radeon HD 7870 2GB Video Card

Two PSU's:
Power Supply: Corsair Builder 430W 80 PLUS Certified ATX12V Power Supply
And
Thermaltake TR2 600W (heard it's crap)

Which PSU should I use to make sure GPU works?

    7870 need 160W w/o OC.

    So better find a 550/650 W Psu so u can CF later than that Cx 430 V2.

    I suggest Xfx 650 W Pro Core or Tx 650 V2 that is on sale on newegg.

    or

    The Xfx 650W is made by seasonic.

    Also the Tx 650 V2 is made by seasonic so you cant go wrong.

    77W Cpu W/o OC
    160W Gpu W/o OC
    15W Hdd
    25W Dvd
    16W Ram

    =300 W lets say you want to CF =560W W/o OC. Add 40 W and here we come to 600 W.

    The Xfx 650W deliverd 720W on the 12V rail so its way enough.

    Good Luck !

    Edit : If you already have those 2 PSU use the Cx 430 V2.It will power your system way better than that crappy TR2.
  2. For a single 7870, an XFX/Corsair/Seasonic 650W PSU is overkill. A mere Antec 520W or thereabouts will be plenty.
  3. I think i'ma get a corsair 650w or 600w

    thanks though guys
