Will this gaming setup work?

this is the build that i'm gunning for
i5 3570k 3.4ghz
asrock h61mvs
radeon hd 7870

for my psu im going for fsp raider 80+ bronze 750w which im really not sure if it's a good psu to begin with. not sure if it will last. i'm running on a budget atm but i dont want to replace the i5, the mobo and the gpu that's why i chose the fsp raider. im planning on overclocking my rig as well. just wanna know if the fsp raider is worth it or if i should invest a little on another psu.
