Do i need a larger power supply?

This is my build:

intel i3 3220

Gigabyte radeon hd 7870 2GB OC

Asrock b75m-itx

Seagate Barracuda 500gb 7200rpm

Bitfenix prodigy

Corsair cx430m

Is my power supply enough to run this system or do i need a larger one?

I think it will be fine but brennanriddel will know for sure.

Ok Thanks

Looks like he is gone for the night though.

I'd say it would be fine, but AMD reccomends using 500w + for your GPU, so it really depends what you think.

If you decide you'd like to go bigger, i'd maybe go for a corsair VS550, I use it w/ a 7870, works great, I just wish it was modular.

Yea if i do upgrade my psu it would have to be modular but thanks for the advice.
