from completed build Leroy Jenkins -- The Price-to-Performance King
Semi-modular, simple design. It powers everything effectively, and has not burned down my house. Silent fan.

Really solid PSU. Only issue I've had with it is that the 8pin Motherboard cord was kind of short, but it reached. The included plugs were wonderful and fit everything I needed.

from completed build Assembly: 1 hr. Cable Management: 100 hours.
I don't plan on adding an extra gpu (at least for now, my needs are met) I read many reviews and found this one at jonnyguru. The 24pin cable is a bit stiff. Fan is silent. The modular cables are flat/ribbon style. Would be nice if the cables all looked the same.

I had an idea that the power supply was not a good component to skimp on. I also wanted it to be efficient and quiet, so I sprung for the Gold Certified one. It's bulky and solid as a brick. Glad I went with the semi-modular power supply, too--there would have been no place to hide extra cables.
This was also nicely packaged. The extra cables were in a drawstring bag, like a Crown Royal bag only not velvet.

from completed build A Xeon Leap Forward (First build)
I took away one star as I felt the cpu cable should really be 5cm longer. If I wanted to have the fan facing up in my case, the cpu cable would not of been long enough to route behind the motherboard. Apart from that it works and its pretty much silent. Also, this was mostly my fault for not double checking but the power cable that they deliver to Australia has the American power socket and the cord is really short.

from completed build Under 1k budget build.
Works well. Gold rated and I trust SeaSonic PSUs more than any others. It was also $10 cheaper than what's listed here, but for some reason I couldn't change the price.

This is a great psu , it runs really quite doesn't put off any kind of smell and feels very premium all the way from the packaging to the unit yourself. This brand has won my loyalty and will be the only brand of psu I will buy in the future great product I could see the care they put in their products with this one.

It's quiet and reliable. If you plan on overclocking this doesn't have alot of headroom. Would recommend a 650W version of it if you do plan on overclocking.
