Q: ok so i'm building a high gaming computer. my question is i'm a getting a Full moduler power supply my question is do i have to buy the cables for power does the componets i buy come with them??? oh and by the way just curious what happens if you touch thermal paste with your finger???: All the necessary wires with come with the PSU, modular or not. And nothing will happen. It will just feel like grease. Just go wash it off w soap

Q: This type of cable with the armor without expert advice, thank you. More: Is there a problem driver in Device Manager? Should be driven by the problem

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: And my other drive has the only analog audio cable on my motherboard hooked up to it, and i know i need to plug in one more cable, because windows wont start up the way i set it up and idk what needs to go into which port.: Are your drives IDE, SCSI or SATA? If they are IDE, are the jumpers set correctly for master/slave or cable select?

Q: If you have an electrical device (e.g. a laptop), you'll sometimes notice that near the place where you plug the power adapter into it, there's a sign. It's composed of 3 circles, minus on the left, O inside a C in the middle, and plus on the right.What is this? And if I want to read/learn more about it where should I go?: If you look at the jack that go inside the power input you will see that it is an outside connect and an inside one.The O is the inside connect and the C is the outside one.Because it is a DC power adapter it has a + and - polarity .O,the inside ,is the plus and C,the outside,is the minus. Also on the adapter you can see the same thing! This is because some brands use the outside connect as + and you can burn your device if you use it!!!!

Q: Help in English:do these expressions have exactly the same meaning?: A cable is usually thicker than a cord. When I hear power cable, I tend to think of industrial machinery.

Q: I'm going to be running 1/0 gauge power wire in my car. My amp only accepts 4 gauge. Is it better to run 1 the whole way through and use power cable adaptors to fit the amp or run the 1 gauge into a distribution block that sizes the output wire down to a 4?: 1 gauge to the d-block, 4 to the amps/caps.

Q: I need this for my HD slim that just gets power from USB and my music class the USB items they use suck all the power.but i have a wall USB power source.: Yes I'm sure this would work. Just solder the red and black wires to an other usb cable and leave the other 2 data ones going into the computer. Plug the power usb cable into your adaptor and It should work. The device is still getting the 5volts it needs so I see no reason why it shouldn't work.

Q: What is the meaning of YJVVV and VV22-4 * 25 + 16 in electrical appliances?: 2.5 square copper (green, with the threading tube) theory will be able to withstand about 20A current, consider the pipe, temperature and other factors, so according to the actual can withstand about 3 kilowatts of power. In fact the 2.5MM2 copper wire is generally open 16A can withstand about 3.4 kilowatts of power.
