I was looking at the 1200W model recently which steadily sits at $599 and noticed this 1500W one on sale for "just" $519 at Mwave.
I've had great experience with my previous be quiet! PSU, my Dark Power Pro P9 has been running great since 2011.

If you have a newer GPU and don't like using the 4xPCIe => 12VHPWR adapter that comes with your GPU, you can also grab their new 12VHPWR cable at https://www.mwave.com.au/product/be-quiet-12vhpwr-pcie-adapt… ($29 + delivery). Umart has it for $25 (https://www.umart.com.au/product/be-quiet-12vhpwr-600w-pcie-…) if you live close to one, but the extra $11 delivery cost made me go with Mwave. Unfortunately it does not come with the PSU.
Free delivery if you're subbed to mVIP.
It doesn't even have a Fanless mode :O
