    I mean what can I say, it’s a great PSU. The packaging itself is really organized and protected. The only down side is that the cables are a little rough and hard to maneuver to certain angles depending on how neat you like your cable management to be. Overall, great PSU & will definitely buying for my next all-white build!

    Great product. It's been in use for over a year now. There have been zero issues. The operating temperatures are low even with heavy use. The modular cable design features provided a clean install because you only use the cables that are necessary to power the components you install. The power seems to be clean.
