I didnt need all the cables, so I was able to put them aside for a time when I may need them. No noise, fit well in my tower, and it does everything I would expect from a power supply unit. If it lasts five or more years, I will feel I got my money worth. I have had no problems with it, so as of now, after 6 months of 24/7 use, I am happy and do recommend this product, even though it is pricy.
