can I run i3 3220 3rd gen cpu with a generic 500w psu? I know that Intel i3 TDPs are really low, but still, will it cause any trouble or issues....? my other peripherals are GA-B75M-D3H rev 1.1 mobo, sapphire 6670 gddr5 gpu, 500GB WD 7200rpm HDD, a Samsung dvd rom, a Samsung dvd RW and that's about it .... so, is it okay to run this rig with a generic PSU? I am saving for a good psu but don't thing will be able to get one for the next 6 months at least..... :/
