Need a PSU for my hp p7-1414

[croxfade]

So a friend of mine bought me a graphics card Sapphire Radeon R7 260X 2GB GDDR5 HDMI/DVI-I/DP OC Version PCI-Express Graphics Card 11222-06-20G for my birthday without knowing the requirements and stuff for an upgrade. My pc is hp p71414 with these specs. It has a 300W power supply but I need a 500W power supply at minimum to run this graphics card. So can anyone suggest me a good PSU? Also could you guys let me know if this graphics card is suited for my system or not. If now which card should I get?

Thank You

A cx500 is probably the best
