Don't lisen to anyone that is proposing pirating the OS.. That's literally the dumbest thing to do as God only knows what's inside all of those cracks that make the OS work..
Besides I'm not so sure your current psu is up to the task of supplying enaugh power to all of the components. For example i have a 650W 80+ bronze and my psu barely makes it when supporting R9 390x MSI Gaming and a q9650 wich probably has far lower power consumption than an i5.
Truthly speaking to be absolutely sure You'd need to check amperage value(s) on the +12V rail for the psu as comparing the amount of amperage You can provide to how much your system will use is the proper way of calculating nessecary psu power. The wattage numbers on psu are just for reference as it depens heavily on how it was calculated from +5V rail +12V rail +3.3V rail etc.
The problem is modern video cards consume far more than previous models especially those R9 series (mu one goes up to 350W)
Ideally (if You plan to use your rig for 1+ years) you could also think of a more efficient psu than your components demand, as capacitor ageing in the psu drops power output efficiency around 35% thus a far grater psu is required.
