Hey guys, I'm planning to upgrade my PC with a gigabyte gtx980 g1 gaming, the i7-4790k and a MSI z97 gaming 5 motherboard, along with extra 5 case fans.

I would overclock the cpu (from 4GHZ to 4.5GHZ) as soon as I get it. I'm currently running my system on a cooler master extreme 2 725w PSU and I don't really want to upgrade it further. Would this PSU run the upgraded system (including OCed CPU) with no issues? I will definitely not go over 4.5ghz (the normal OC limit for the cpu). Any advices will be helpful, thanks!

My friend told me I can even run 980 SLI on that PSU, I shall see in the next few days when I have my stuff built. Thanks for the answer
