Data cable is decent. He suggests what to do. The Power Splitter, on the other hand, is an express strip to light up your home. There are several YouTube videos available on the web that talk about the risks of using a SATA power distributor. In short, using a SATA power strip poses a risk of fire. Proper maintenance can reduce the risk of fire. The splitter included in the kit has a molded body (if you look closely at the connector you can see that the cables are molded in plastic). The problem with this type of connector is that you cannot see what is going on inside the connector. Are two copper cables touching? or loosened and there is a possibility of sparking? Consequently, there are reports of this particular type of cable causing fires inside the case. I strongly advise against using this cable.
