Okay here is the deal, I got this product and it didnt come complete. I have a cable modem, and I only got 1/2 part of the power to supply it.The part I got is the part where the wire connects to the power socket of the cable modem and then the other part of the wire ends with a power supply. Then theres like an outlet on the power supply that another wire (didnt get) is supposed to attach to and at the end of the other wire should be a normal plug for an outlet. Well I looked in my garage and found a wire that attaches to the three plug out on the power supply, and the other part of the wire connects to the wall outlet. The question is, will this work, I dont want to fry the modem. I thought that any cable that connects to the power supply and then to the wall all serve the same purpose. Tell me if im right. Thanks!
