I bought some parts for my first build and when i connected the PSU to the motherboard it wouldn't power on. Its a Cooler Master Silent pro hybrid 850w. I tried plugging the psu into the outlet itself and nothing happened. I tried a paperclip method with the motherboard power cord connected to the psu and i put the paperclip into the green and black pins. I tried different black pins and nothing happend. I will probably have to return it to newegg but do you guys know any other way to check if its broken? Because i would hate to return it and find out the problem was the cable or i did something wrong and idk if anything else is defective. Also for the cpu power supply it says ATX12v1 where i plugged that cable into. The cable i used was a a 4+4 pin.
