    Bought a different Power Supply which has more reviews that were good. That Power Supply was D.O.A.. Came back exchanged it for the Corsair RM850x and it simply works great. And the connectors that Corsair has allowed me to connect everything whereas the other power supply would have forced me to use splitters. Much better product for use and convenience and safety. Splitters are not good per say.

    Perfect upgrade to pair with a graphics card update! Fit easily into my existing full size case to replace the stock 600W PSU. Having modular connectors made it easier to route power to graphics and motherboard and avoid having to tame the “den of snakes” from all the unused connectors. Kept the unused connectors in the provided Velcro bag in case I need one of them in the future.

    This psu has actually lowered the heat output ans ,y energy bill versus my old inefficient 650 watt. Corsair is great, at the rate i use it, itll pay itself off in electric savings.
