    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.

    Silent, and has all the necessary connectors for a single gpu setup.

    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
