Looks good to me. 
 
EVGA has some good deals on better power supplies at the moment. Free ship as well.

As Austin86 says, you will end up saving huge $$ in the long run.  Here's an old techpower forum post from over a decade ago before Titanium was a thing.  This shows you the savings from moving from a white to bronze, silver, gold and plat.  Bear in mind that the cost of 1kwh at the time was $0.12 and they are only using a time period of 10 hours per day.  So it would need to be adjusted to your current rates.  There used to be a visual calculator that did all this to show you the savings through a year, but the site is either dead or moved (it was posted in the folding/crypto forums a few years ago).  Oh wait it was crawled by the https://web.archive.org/web/20201212104611 http://www.orionpsudb.com/efficiency-calculator  waybackmachine (won't let me hotlink it so copy and paste these and remove the space I've edited this 3 freaking times trying to resolve it haha). <-- enter in your current PSU, power costs, and roughly what you would be using for load from the three choices and it will tell you what you will save in a year. 
 
Basically buying a Gold to replace your Bronze will pay for the difference in the first year.
