I purchased one of these last year(2017, spring). It lasted less than a year, about 7 months. For RMA I had to pay to ship it to them. Took 3 weeks for them to ship me a "refurbished" unit and who knows how old that one is....Anyway that one was damaged physically. The 20/24 power connector was broken, plastic was crushed. So I called and they had me take a picture. No apology or anything, just "We will ship you out another one tomorrow." So another 3 weeks pass and I get another refurbished unit. Also they packed it pretty poorly in my opinion. Used a box that was only slightly bigger than the PSU itself, wrapped the power supply in a clear plastic bag and left the cords hanging out of the bag. Then they used just one sheet of bubble wrap, so one layer. If anything happened to box the box it could easily go through and damage the power supply physically. I guess I got duped thinking it was good quality due to the Pc Power & Cooling name. However it's not Pc Power & Cooling anymore and is now "Firepower Technology". Shame on me for not looking further into this before purchasing it. I know PC Power & Cooling used to be good and their power supplies used to manufactured by Seasonic, but now that's not the case. Now I'm stuck with this thing since they don't offer refunds. I really don't trust it enough to put it in my build. I read "Super Flower" manufactures this but I've also read SirTec.
