I'm upgrading my psu (XFX Core 450w) to a either the XFX Core 550w or the SeaSonic G 550w psu. The price difference between the two is $9. I know the SeaSonic is part-modular but after looking at some of the pictures of the modular cables they seem rather cheap in quality. I don't have a problem with non modular cables in my HAF 912. Can anyone help me choose which one to purchase? Thank you.
