I like the quality of Seasonic. I bought the X750 for my semi gaming rig and it powers my 2 6950's flawlessly. I never had an issue since day 1. I almost forgot it was there its so quiet.
Dunno anything about Seasonic but what the hell, heres me post
BTW If any Seasonic employee's are reading this.... HELP!!!! my 5 yr old 750 watt power supply is failing, and I have $0 for replacement... (hell I got $0 for for food this week too but at least a new power supply would keep my mind off the hunger lol)
I have had many PSUs under various brands there were made by Seasonic, all have been super reliable. Seasonic made PSU's are always my first choice when building a system.
