Another Gaming pc thread(sorry x_X)

Hello everyone I have chosen the parts to seek needs of hopefully decent gaming rig. Not exactly sure on power supply unit right now..... It says on pcpartpicker that I will only use about 341 watts. I will only use 1 screen and only 1 program at a time. Is it better to have at least double wattage from what is noted as how much I would use? (my last computer basically blew up from over heating and dust accumulation). Thank you for your time =-D Actually thinking of moving the mother board to a asus p8z77-v deluxe instead.

Good PSU. The 670 says 500w minimum. You will be future proof a bit.
