    Does everything a PSU needs to. Very quiet. Easy to install. Easy wire management due to full modular design. SeaSonic makes great PSUs. Only thing I did not like is the fact that you need to use two GPU cables (per the manual) in stead of one. Not really a big deal though

    The rgb lights on my pc are literally brighter coming from a 650 gold evga. The cables like others have said are pretty thin/cheap feeling but it makes them easier to manage without having to wrangle thicc cables through little crevases. Doubt ill have any issues with it but will update my post if i do

    Works great. Very quiet. The only gripe is the a missing gpu cable. However, I don’t seem to need one as I’m not running sli at the moment.

    This is one of the best PSU's you can get. You can search for reviews online for more specifics but you'll be back to buy this once you do. It has performed perfectly without any issues. Definitely a must have for your new builds.

    Top Tier power supply for my build. I bought this because the price was similar to the other 850 Watt Gold PSUs. Many companies use Seasonic as their OEM and I now see why! great PSU for the price would buy again

    Solid power supply, no issues. I've read that it has some safety setting baked in for erratic load balancing, and it can cause issues with an rtx 3080. I'm running a 2080 super and haven't had any problems though.

    Great deal on a plat 850W supply with a "Tier A" PSU list from LTT. When it's on sale it is a must buy if you have any of the new RTX or AMD cards and high watt processor like 10900k or 5900x.

    I was lucky enough to get an EVGA 3080Ti and my Corsair HX 850 could not take it, PC would shut down while gaming. Got this Seasonic 850 and a;; is working great again.
