Q: I am planing to install a 7770 on my PC but i need a pci-e cable to power it on. So is that cable included or i should purchase one?: i might say pass with a 500W capability grant. its basically greater adaptable in case you propose on upgrading this laptop sooner or later. additionally, what photographs card are you utilising? and in case you propose on a bigger photographs card sooner or later, you particularly ought to evaluate 650W. btw a philips screwdriver is a + area screw driving force so its prevalent and that they are basically particular on its shape. which ever photographs you would be utilising, i might inform you to stick to Nvidia over ATI i'm hoping this permits.

Q: how can i calculate the current carrying capacity of a power cable when the area is given?can you give me a table on this?: Table 310.16 of the NEC (2008)

Q: NH-YJV-4 * 4 in NH-YJV-4 * 4 in power cable tube: Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.

Q: I have a Technics SL-D20 Turntable recently purchased from a garage sale that lacks a power cable. The turntable has a 2 prong adapter, but it is not one that has a square and semi-circular portion, but rather seems to accept an elliptical two pronged cable. It is listed on the back as Power Source AC120V 50 or 60hZ 6wThank you: That type of connector was common before the IEC style cable became the standard. Perhaps you can scrounge some more tag sales or estate sales, friends garages and attics. You might check to see if there is an electronics surplus store in your town. Those guys never throw anything away.

Q: On my power cable, (the thing that plugs into the wall, and laptop to charge it) well in the middle of the cord, there is a rectangle black box. What is it called, and what is the purpose of it?: its a transformer to cut the mains plug voltage down to the same voltage as the battery which will be around 16volts to 20 volts for a laptop,the desktop PC will have the same transformer built into the tower casing beside the fan,but you just cannot see it, and there will be a voltage selector switch for the country you are using it in ie-UK =220-240volts, USA=110 volts or similar,both the laptops and desktops use the same internal operating low voltages,and mains voltage would fry everything inside ,that's why they are fitted with the transformers.

Q: i just want to select the power cable but i m having some confusion that when we select single core power cable we take current rating of that conductor but if we say 3-core cable has 200A capacity then it means that each core has this capacity or it is the the capacity of overall 3-cores: Current ratings for conductors are based on several factors including conductor type (Copper, Aluminum, other), insulation material (thermoplastic, rubber, asbestos composition), ambient temperature, length, exposure to weather, and numerous other factors stipulated by the NEC or local Code. The ratings are usually given for a single conductor in free air. Mulitiple current carrying conductors which share a conduit, raceway, or any other enclosure must be derated appropriately. See the source below for Code reference and rules of thumb.

Q: How to distinguish between high and low voltage power cables: 5mm, that is 100: 76 followed by the proportion of push The height of the isosceles triangle at the time of the bend of the 200 high bridge is also suitable for the adjustment of the 90 ° bend; the use of the tool is cut off and the bending of the bridge is 90 ° Bridge elbow As for the length of the bridge to limit the restructuring of the elbow, as long as the use of junior high school learned by the simple mathematical knowledge of the calculation, any length distance can be controlled The use of mathematical methods simple calculation, a variety of angles, the length of the elbow can be made zuo

Q: My monitor POWER cable says: 10A, 250V. my CPU power cable says 6A, 250V.Recently, my monitor stopped working, so as a part of hit and trial, i exchanged these two wires. So, although my monitor is using a 6A cable instead of 10A.. my CPU is getting 4A excess than what its wire said initially.Is this safe?? Will i end up blowing up my CPU??: should be fine

Q: i have a modular power supply i lost my cables moving out of my old house. so can any one tell me where i can get new ones to my power supply:: I don't think you can, really... Modular power supplies come with cables, they are not one size fits all, every brand and even every model might have different cables and plugs. Contacting the manufacturer will be your best bet, but it might not be worth it, might as well just buy another power supply, it's only another $45 shipping and all.

Q: my cable often gets unplugged soo im really worried that i may loose 280 dollars?: The process of unplugging the power can cause unpredictable power spikes which can damage any component in your PC - including the graphics card. You should address the problem of your PC getting unplugged before spending more money on hardware.
