Q: I have dell optiplex 755 @ Q6600I bought a new graphic card, HD4850it requires 2 IDE power connections,but my computer has just SATA connections.I saw sata-to-ide converter in the internet,but in my country there isn't any store that sells it.What should I do ?: You don't have a PCI-E power cable from the PSU? You might need to upgrade your power supply as I'm pretty sure your power supply will not support that video card.

Q: my laptop only boots on the battery but not when power cable is plugged in?: Sounds like you have a good battery. Is the battery plugged in when you try to connect with the cord? Does your battery charge when the cable is plugged in? If not, you may need a new power cable. Use a VOM (VOLT OHM METER) on it and do a continuity check to ensure connection is good. If that's not the problem, it may be the DC Plugin port.

Q: ill exlplain more the battery is connected to one end of the fuse then i want to run 2 power cables out of the other end to both of the amps will tis work or will i just loose power the fuse is 60A if that helps. 60A is massive why a fuse that big is needed i dont no: You will need to run a wire to each amp using a fused distrobution block as mentioned. A 60 amp fuse isn't really that big for car audio. Some amps can pull 80 amperes. This fuse is really only there to protect the power wire from being shorted.

Q: It's provided to me by my ISP which is Cox. If I were to unplug the power cord what would happen, would my phone no longer work without another technicians appointment. I know that the motorola cable modem with no phone service you can power cycle that one.: Turn off the modem. Wait 5-10 seconds. Turn the modem back on. If there isn't an on/off switch on the modem: unplug the modem, wait 5-10 seconds, plug the modem back in.

Q: hi i need to connect a extra cd rom drive to my computer and dont have enough 4 pin power cables in my computer how would i get those and how would i install those. Thanks: These are called Y-Cable. Buy one. Remove the power cable from the old cdrom. Attach it to the newly purchased cable. Now you get 2 new points. Attach one to old cdrom and other to the new cdrom.

Q: Why do phone lines stay on when other lines power and cable will go out during a storm?: The phone lines are powered by batteries at the phone company offices. When power goes out in general those lines retain their own source of electricity.

Q: How should connectors for storage device cables and connectors for power supply be described?: Storage cables have basically 3 types: IDE, SATA and SCSI, and are referred to by those names. Power connectors are sometimes called molex connectors after the company that first made them, or just power connectors and their applicable voltage they supply.

Q: On my original PS3 power cable it says 10A 125V, do I have to make sure the cable I use from a computer matches the same?Also can you explain how it works if the cables don't matter: Fat Ps3 Power Cord

Q: So I use my laptop with power and only put in the battery when I take it around. So I sat my computer down and it abruptly just shut down. I powered it on and I set it down again and the same thing happened. The third time it went all the way to the desk top. I touched and moved around the power cable connected to it shut down. WTF: sensitive power supply connection i guess

Q: Only the ground cable is green, the two other cables are gray and I noticed that one is with stripes the other is not... The maker is Smart Choice. - there is more clue, one cable end is coded with a letter Z , other W , than G .... the G is probably the ground ( green ) . I need to know which one will connect to the black wire and which to the white one. Please help. Thank you: The neutral or grounded conductor will be the one with the stripe or ridge on it. This will connect to the white wire or neutral connection on the dishwasher. You can follow it down and see that it will be the wider of the two power prongs. Green or bare will be for equipment grounding and will connect to the frame of the dishwasher. Usually this is a green screw.
