I'm very happy with this product, it does the job!
The cables are long enough and well made.
The brand is well known and reputed for its quality, which I certify by its use! The only problem with this one is that there are two 8pin to 8pin cables to power the cpu (indicated in the description). The only thing you need is one! I'm not sure if it's a good idea to use a pcie or molex or even sata cable instead of the 8 pin cpu cable. It is a great product!
