So basically i got an i5 3470 + 16gb ram, with a recently bought GTX 1060. I got a Raidmax Cobra RX500AF 500w bronze 80+ , everyone says its crap but it stills works after 6 years. I dont really have a budget to buy a new PC so i want to upgrade my CPU to a i7 3770k but should i upgrade my PSU first? In my country there is not a lot of choice all are crap but i was looking at Antec Earthwatts Gold Pro 550W Semi-Modular, is that psu good?
