Hey, I've made a PC on pcpartpicker.com. I chose all the components except for a GPU. I will be buying a graphics card in the near future it will be a r9 280x. I also have a Windows 7 CD. I'm just wondering if all my parts work well together and does my power supply have the right connectors for the r9 280x and my motherboard and hard drive. Feel free to recommend better parts but my budget is $550 including tax and shipping. I live in BC, Canada so tax is like 0.12%. Link to build http://ca.pcpartpicker.com/p/ZfNBGX
