Excellent power supply. Would buy again.

Low-noise first-time-builder recommended PSU.

Matt_B03 5 points 8 months ago

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

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.

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!

Quiet and fits in any case

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.

Certified, what more do you want?

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.
