Opinion on my build

I would find a better PSU, and the Motherboard...the B85 is a dead end from what I am reading. You are much better off with an H97, H97+, or Z97. And you can find one for about the same price. The ASrock Z-97 Anniversary is a favorite, I like my ASUS H97+ (I don't plan on overclocking)

Also, your RAM seems overpriced, I would recommend GSKILL RipJaw 2x 4 GB DDR3-1600.
 


What would you recommend for the PSU??
 


This is a good price for a modular PSU,
EVGA SuperNOVA GS 550W 80+ Gold Certified Fully-Modular ATX Power Supply it's about $60

 


Australian prices are different from US.
 


Ah, my oversight, the differences aren't much, but the availability and markets make it more expensive. My apologies.
