I am planning to get a MSI HD 7970, I know this is the previous model of the R9 280x. I have looked around some sites and it apparently uses less power than a R9 280x. I am just wondering will my 550 watt Seasonic PSU (http://www.seasonic.com/product/pc_atx.jsp) be able to power everything?
Note. My CPU is not OC'd but I might OC the GPU
