Cooler Master PSU's do not have the same warranty and are known to be less reliable, don't cheap out on your PSU.
I have heard a lot of good things about cooler master PSU's and it has all the connections i need plus if i want to go SLI on my GTX 970's i have enough slots same as the EVGA one and its not that expensive
It's your money do what you want, the Cooler Master Unit is a high end unit, but quality control and customer service (EVGA's customer service is legendary) is not on the same level. Also the Cooler Master is only bronze rated, not gold.
