Pros: Fast, matches my silverstone case well

Cons: With regards to staying on during sleep/off, I also had this problem at first. You have to go into your bios and enable the USB power off/selective power saving or whatever that feature is called. On my ASUS Maximus, it is called ErP.

Overall Review: I egg off for being confusing with regards to the power off setting. Nothing is mentioned in the manual about this but Silverstone does mention it on their website.
