I need help choosing a PSU. Is 750 too much or will i be okay with 700W? If 700W is fine then will this one okay; 700 Watts Power Supplies (Cooler Master B700 B-Series Gaming Power Supply)? Due to my budget, this would be the only alternative I could afford. Your opinions and suggestion would be greatly appreciated.

I also need help choosing a motherboard to compliment the rest of my build. Would; Gigabyte Z97X-SLI INTEL fit well, as opposed to the mobo in my build? Bear in mind, this is purely for gaming and streaming.

I just answered that in your other identical thread.

Ok I saw a few red flags here, first off your not going to need a Z97 motherboard if you don't have a "K" series chip (overclockable). Secondly, that CPU cooler will NOT work with that socket (cooler is LGA 1155 and Socket is LGA 1150). Sorry if im confusing you, but you dont want to make these little mistakes.

no, im still grateful for your contribution. I did however find this from another forum answer, "LGA1150 and LGA1155 sockets have the same holes for mounting CPU coolers, meaning a cooler that supports 1155 socket will support 1150 boards, and vice versa."

I think im in the clear.
