Very good power supply because of its modularity and the length of the cables which were very studied at least for my medium tower but I suppose that for the large ones or the towers of gamers that must be the same one! All the cables are present and my configuration with three hard disks and a DVD burner found without problems what to be fed and the whole to heat up beyond measure and in the silence!
This is my first semi-modular power supply to replace an old enermax500w power supply. Easy to install, the cables are long, no worries about connections.
No or extremely low noise. I have the impression of a slight improvement on the responsiveness of the elements.
In my first impression, I am very happy. So I highly recommend this product.
The product is very good and corresponds perfectly to my expectations,
the fan is inaudible,
The only drawback inherent in the large grills is the risk of dropping a screw or other object inside (I had to dismantle it once and shake it)
