To say that Seasonic makes good PSUs is an understatement. I really liked their regular S12 model, and this one only improves upon it. Rubycon 400v bulk cap and Nippon Chemi-Con for the secondary side, plus one solid cap on the +12v rail (seems to be a NCC too but it's difficult to make out). That rounds up their excellent choices of capacitors. When [URL=http://enthusiast.hardocp.com/article.html?art=MTM2NCwxLCxoZW50aHVzaWFzdA==]put to the test[/url], the S12 II actually performed better than Seasonic's own specs, which in the PSU world is almost unheard of.
