your build is fine and the mobo can support up to 3100Mhz RAMM according to the ASRock website, i would suggest that you change that PSU as its not suitable for Gaming purposes you can get anything from XFX or EVGA 550W/650W G2 these are top of the range PSU's, also you should go for an I5-4690k or the newer I5-6600k (you would need to change mobo/ram for this) i5's offer way better performance to the $ than i7's do and nothing no game need more than the i5-4690k offers atm, look into getting 16GB of ram as games in the future will need it, everything else is nice.

Why is my psu bad? It's in tier 2 of the psu tier list.

no its not its in tier 3 on the list, the RM 850W is in tier 2.

RM Channel Well Technology (450w - 650w, 1000w) / Chicony (750w) < all of these are tier 3 meaning they are not suited for an overclocked gaming computer.
