PSU amount required?

[jeffparjout1]

Specs:
GPU: Powercolor Devil r9 390x hybrid
CPU: I5-4690K
Ram: 4 x 4gb gskill
PSU: 750 bronze?
Perif: led fan controller, nzxt lights, cd read/write, 9 case fans and 2 radiators.
SO my question is, is the 750 watt bronze enough? I noticed that certain wattage calculators say i use about 750 watts, some say less? I would like to upgrade to a 1k watt gold evga. I don't know if this is really relevant, but I live in an area with terrible, dirty electricity and I already fried one of my mobos for reason I have no clue.. So the question stands, keep the psu or upgrade?

750W will be enough ..but get a good quality one like
seasonic/evga b2-g2-gs-gq series / corsair cxm (new generation)-hx-ax-rmx-rmi-axi/xfx pro-xtr series / superflower

your gpu card will use max 451W at full system draw
