After modding my AT case for this to bolt in, it's very solid, quiet, and has plenty of power for my system

I got this as my 2005 Turbo Cool 850W PSU did not have enough connectors/correct ones to power the new GPU. This is the 3rd PSU that I got from Best Buy and they were very nice about returning the other 2. First one was the Bronze model of this which I got and it was apparently an open box as it was missing 2 runs of the sata cables. I should have known something was off as one end of the plastic wrap was missing but thought that was normal as last time I got a PSU was in 2005. Returned it for the Corsair RM850x as It was listed as $75 on the shelf and one of the employees conformed it BUT at check out it was $150... I vowed to never shop at best buy again... Only reason that I came back was to return the PSU as it didn't work... It apparently is not compatible with my MB. It is ATX 3.1 which after reading up on Corsair did away with the negative 12 volt run and it is now a modulating voltage and left unpinned... So back to BestBuy! Knew that the bronze worked with my system so I looked and found one store with the Gold one and made sure that the box was unopened. So switched it out and now I have a working pc once again!!! This all started as I went from a Geforce 960 to a NVIDIA GeForce RTX 4070 Ti Super on my (apparently 2014) Asus Strix X99 Gaming MB which is apparently impressive as the original psu was from 2005... Which prices are way cheaper as in 2005 the Turbo Cool was around $350 for the 850W. Now looks to be around the $150 price for 850W. SO backstory done. This psu works well and provides enough power to do what is needed and so far their has been no issues with anything. The easy of cable management is way better than 2005! The 8 sata connections is good as I have a dvd drive and 6 hard drives to power!
