I got my PSU from Newegg, Rosewill 750w Photon (Gold Certified) for $79.99 USD (which would be around $120 New Zealand dollars) at the time of purchase. Personally I haven't hooked it up yet because my build isn't complete, but on Newegg it recieved 4 out 5 eggs for 90% of people for the price. I've noticed corsair PSU are usually a bit more expensive, I'm not sure about cooler master though. But for the price and being 750w Gold it was a good deal.
