    Great buy, bought this as a backup for my rig. 80 plus bronze does the trick in most scenario but if you have a power hungry chip or gpu. I wouldn't go below 80 plus gold.

    Only had it for a month or two, but no issues yet. While not fully modular, the only hard-wired cables are for the CPU and the motherboard that you'd be using anyways?

    Good value power supply. I like the semi modular design. I'd prefer a little more distance in between the SATA plugs but my issues may be a function of case layout rather than the cords.

    I wish I had spent some time googling this before buying. To summarize it doesn't handle heat well and will start getting flaky at around 130F that's pretty low for a PS that is probably going into a gaming rig.

    Very good psu, made perfect sense for my build. However, it does not have as many pcie/cpu cables as you may need for modern builds.

    My wife's 'puter had a PS failure, so we needed to get something new. This has enough power to run everything comfortably and has been doing a great job of it.

    When I queried the Geek Squad what else was needed to improve Chris' gaming experience, they installed this power supply to help with the graphics card. Can hardly wait til Christmas!

    Not for gaming motherboards. It doesn't come with the proper connections. Yous should spend the extra bucks and go with the RX which I don't believe that best buy stocks

    I ordered this one off of New Egg and it was DOA, I was very disgruntled! I went to the local Best Buy and purchased the same unit, AND they price matched New Egg. Can't beat it!

    Replacement power supply for my HTPC, it replaces a 1000w which was overkill but it does the job nicely and quietly.

    Gets the job done in usual reliable Corsair quality. Power cables are stiff, and braided covers would be nice for the price. Single plug cables would (pcie) ice to neaten up installation.

    I've never have any issues with my Corsair power supplies. They are quiet and with it being modular. It reduces the amount of wiring in my case.

    I've had this unit installed for over 6 months and not a single incident. Bought it so that I had more flexibility with wiring.
