0nly222 :
im going to order the following Components:
MSI GeForce GTX 970 Gaming 4GB
Intel Core i-6600K Skylake
MSI Z97 GAMING 5, Socket-1150
Corsair H80i GT hydro Series CPU Cooler
but i dont know how much watt i need in the PSU.
thanks
Am guessing thats an I5-6600K since could not find a I7 at that version
At a rough guess, considering your MSI requires 145W and your I5 requires 91W.
I would look at either the EVGA Supernova
here which is fully modular or possibly a higher
EVGA 750W if you want to make sure all future potential upgrades are covered. Assumption offcourse that your budget coveres this.
I have the 650W one and love it as the fan does not come on until the PSU hits a 25% load under Eco mode, which means its really silent.
Keep us update on what you decide to do or post a picture of your build once its all done
