A bit of history first: I purchased a COOLER MASTER Silent Pro M700 RS-700-AMBA-D3 700W ATX12V V2.3 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply back in May of 2010 and it has been working great. I also purchased two SAPPHIRE Radeon HD 7970 DirectX 11 100351SR 3GB 384-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card OC with Boost (one for my PC and one for my kids PC) back in November of 2012. My kid no longer needs the PC and I thought, why waste a graphics card, why not have both in my PC and CrossFire the video cards. When I look at the power supply https://www.newegg.com/Product/Product.aspx?Item=N82E16817171037, it has only 2 x 6+2-Pin PCI Express output ports/connectors. My question are these: 1) Are there any cables that I can buy that will split the 6+2-Pin PCI Express output ports to allow me to run power to both video cards? 2) Or do I need to purchase a different power supply that has 4 x 6+2-Pin PCI Express output ports?
