Closed Compatibility of my GPU Tags: Graphics Cards GPUs Power Supplies Graphics Product Last response: November 27, 2012 4:14 PM in Graphics & Displays Share ilumunus November 27, 2012 1:21:40 PM 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?

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. http://www.newegg.com/Product/Product.aspx?Item=N82E168... or http://us.ncix.com/products/?sku=59616&vpn=P1650SNLB9&m... 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. http://www.hardwaresecrets.com/article/XFX-PRO-650-W-Co... 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.

A mere Antec 520W or thereabouts will be plenty.
