    Functioning perfectly, and quiet. First time using a component based PSU and love the flexibility and cable reduction in my case. Would definitely buy again.

    This is a great power supply, perfect for many people. I highly recommend a fully modular PSU, as that way you only need to connect the power cables you need and do not have extra cables in your PC case. Fan speed is adjustable.

    I eventually returned mine for the corsair 1000x psu, but this one worked out extremely well for me while I had it. No issues, easy to control the watt output, and it's very reliable. Great for all budget builds and a couple of higher end pc builds as well.
