Please recommend me a power supply for my Lian Li PC-V354.

I have a Lian Li PC v354

I need a specifically designed power supply. If i get one of the many power supplies that have the 120mm fan on the top and install it in this case the fan will be directly against the case side, then there will be no air flow. So it seems that I need a power supply that has the same setup as the one I have now. an 80mm fan one each end of the supply.

Please recommend me a quality power supply for about $70 to $80 that is 500W+

Thanks
