Rated 4.7 out of 5 by 3 reviewers.
Rated 5 out of 5 by Excellent product. Quite and powerful, easy to install Does everything a PSU should do. The modular setup is really good, You only have to use the cables you actually need. The cables are thin and flexible. I would recommend this product 24 May 2015
Rated 4 out of 5 by Pretty Good. Had to get a new power supply as my computer was having some serious problems, so this was first on the list as voltages were all over the place. The unit it self is nice and easy to fit, feels solid and give the impression it is built to last. The leads are easy to fit into the power supply itself, the down side was fitting them to the motherboard, the main power lead is stiff and trying to get it into the position you want a little awkward but not impossible, the other leads are easier, but by the time you have what you need connected you are repositioning them as they want to go back into the shape that they have been sitting in, when they were packaged and that tended to be to close to fan blades. Now I wont lie this has been the first time I have ever had to do this and there are more reviews to come as this was one of many faults that needed sorting, but I would recommend this product as if you get a more up to date case that would help with the positioning of the cables, but the ease of fitting them was a big plus. One thing to take into consideration is the plugs that connect to the motherboard, when connecting them they don't give the feeling that they have 'locked' into place but after checking several times they were all okay and everything powered up on first time of asking. 26 February 2015
Rated 5 out of 5 by Excellent unit. A sturdy well made solid unit. Multiple leads. Great value and quiet as you like. Would highly recommend. 17 January 2015
