    Purchased to replace bad PSU that came with a prebuilt gaming PC. Overall way better than any other 3rd party PSU's. This or EVGA you cannot go wrong.

    Love the interchangeable cables! Should be a standard feature for all PSUs. Fitting it into my case (which is probably about average sized) was a pain tho.

    CORSAIR RMx runs great and with minimal sound may be a good pick up.

    It works as expected, it could be nice that they added two sizes of the same cable to reduce the cluster!

    Great for current gen pc builds , only complaint is the lack of individual pci cables , only pci cables included are 3 double connector cables which is the reason for only 4 stars
