I am currently building a pc and i'm wondering if the 400W cooler master elite power is good enough. I have already bought and can get a refund but i'm not tech savvy so any help would be great.

My Specs:
-Intel i5 6600K (i probably wont overclock it)
-Nvidia gtx 960 4gb windforce OC
-2x 4gb ddr4 RAM
-2tb seagate barracuda HDD
-2 LED 120mm case fans
-Cooler Master 212x
-Gigabyte H170 D3HP motherboard
-(i have no optical drive)

P.S. I have used the eXtreme Power calculator but as I say i am not tech savvy so i really don't know what that was telling me.

Thanks, Hugo
