    This power supply came in with no issues via mail, or damage, and has been working flawlessly. While it is a little large for my mid-sized case, which isn't really a problem it just made connecting and inserting it a little more of a challenge than it needed to be, it still does fit in my case cleanly. I'm looking forward to my future upgrades, which is part of why I got the bigger supply for now.
