No deep insight, but this is a great unit so far. It's smaller than most SFX-L units which helps bridge the gap between small and powerful. Plus, they gave a $25 Steam gift card for reviewing on the purchased website.

Quiet. Works fine. Solid. Nothing bad to say

I guess SFX power supplies are expensive. Initially I bought the 450W version, but returned it immediately because I didn't think it met the minimum requirements for my graphics card (I was still deciding on graphics cards back then). A 500W power supply would have been sufficient, but Seasonic doesn't make one. There is one by Silverstone, but I wanted to move away from that brand. When I compare the Seasonic with the Silverstone, I think the Seasonic has more room around the connection points. For this price, I wish the cables were of better quality. For example I had a really tough time managing the cables going from the power supply to the motherboard. The cables need to be twised 90 degrees because of the orientation of the power supply.The motherboard cable design seems to be proprietary and I couldn't use a cable from another brand.

Quiet and works flawlessly, and the 10-year warranty is comforting. Cables are just the right length for my mini ITX build. Includes an SFX-to-ATX adapter plate. Only complaint is that the drawstring bags it's packed in are cheap this time, which is so minor that it's not worth lowering the score over.
