from completed build Desert Thunder

Tier 1 rated Seasonic X Series X-850 850W 80 Plus Gold Certified Full Modular PSU. It’s whisper quiet, it comes with a 7 year warranty, and is more than enough for what I need right now. And if i should decide to SLI in the future, I should still be fine. The cables are nice and long (no problems reaching components in my new full tower case) and come in nice storage bags. This was the first PSU I have ever used that comes with flat cables.

The SeaSonic 850W was chosen for its reliability, and 80 Plus Gold rating. And frankly guys, in my experience, you can never go wrong with SeaSonic.
