    Best bang for buck semi-modular PSU I could find. Looks good in the case and does the job. Glad that the cables were sleeved black!

    Low-noise first-time-builder recommended PSU.

    An excellent performer, and superb in terms of wattage-to-price. Plus it gives me ample headroom for when I decide to upgrade the CPU/GPU.

    It is proving power to my system with no problems, so far. This is my first build, so I maybe judging this harshly, but the cables seemed very stiff, which made cable management more difficult.

    Really small PSU now that I look at it lol. Uses its own modular cables which is weird but at least the cables are all black. Not much to say.

    Not sure i'd recommend this product. For £10 more you can pick up a Corsair PSU of the same specifications that has better contents.

    So I wanted at least a semi-modular power supply to help with cable routing and I would definitely recommend it. Seriously, either buy a case with enough spare room to dump all the extra cables or spend a little more on semi-modular or even better a modular power supply. No complaints with this.

    Solid semi modular power supply with a 5 year warranty. Quiet as well. Would recommend.
