    This PSU is actually a bit old, and I was concerned about that a bit. However, it functions well, and I managed to tolerate the mess that are non-modular PSU's.
    Came with some velcro strips and wires were wrapped nicely. Just wish the wires themselves were also sleeved black instead of factory condiment colors.

    Wanted to go for a stable high quality PSU. Works good and is silent enough!

    There a lot of cables for this PSU that I had to mangle through. But the quality is nice without all the ketchup and mustard cables plus a 5 year warranty.

    No issues. Surprisingly handles a 1070 and a 6700k.

    A nice psu, no issues with it right now, and a bang for the buck

    Great psu. My only niggle is that i could use a few more inches in length on the sata cables and i could really do with the connectors being space out a bit. But still been really reliable for 2.5mths now.

    Great value for the money. Is the right PSU for the 99.99% of the builds
