    Modular power supply and very good from what I heard of the RMx section of power supplies. Comes with a lot of cables however these cables come with in-cable capacitors along with being stiff in general which impeads cable management. Might consider getting less stiff cables in the future.

    The cables are gigantic and hard to manage. It supplies power. Unfortunately, the plug on the back will not fully rest in the PSU, leading to random shut downs and losses of power. This hasn't happened at any important time (yet) but the best solution I came up with was just to support the cable with a large stack of Magic The Gathering cards.

    It's the weak link in my PC, and I advise /everyone/ against it.

    A high quality PSU, it has a pretty nice metal sticker bundled with it.

    Does what it is supposed to do, but the cables aren't the nicest.

    from completed build Blackout w/minimal RGB

    I wanted a fully modular PSU and this was the cheapest one at the time at $50. Reliable, relatively cheap, and not too much more than the typical semi-modular bronze certified PSUs. I plan to put in custom sleeved cables in the future, but for now, the all black cables are fine.

    Love the packaging it came in with the felt bag for all the cables it really felt premium. Also a seriously quiet power supply. However, the cables that came with it are quite stiff so building with those cables are a bit difficult.
