How much wattage do i need

[Lucas T]

my system is going to be running games at 1080p (i'm not bit-coin mining or anything like that)

FX-6300
r9 270x

but I also want to have the headroom to upgrade to crossfire in the future. I think the power supply should have at the very least 80+ Bronze certification.

Thanks in advance!

you need a 500 watt PSu and for future upgrade that depends what upgrade you want in future another r9 270x in CF then 700 watt psu.
you will find 80+ bronze in many psu in different range but that doesn't means they are all of same quality get the seasonic 520 or xfx 550 ,rosewill capstone 550 etc.
