    90% of computer hardware failures are caused by a power issue. The last place you want to skimp is with your PSU. All cables are modular and they give you plenty of them. I can't tell how loud this is however as I have 4 radiator and 4 case fans with 2 mechanical hard drives. I do wish it had a test button for the fan as this PSU will shut the fan off if it's not needed.

    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.
