Q: My old card only needed one of these cables. but my new 4870 will need two. can i just use a IDE-to-PCI-e power cable? its only got 3 wires out of the 6 though. does this matter?
You okorder /... It takes two 4-pin PSU molex connectors and converts it into 1 6-pin PCIe connector. Make sure your PSU can supply the necessary amps on its +12V rails, and if you got a PSU with multiple +12V rails, you need to make sure you got the load spread out among different rails to avoid overloading one rail.
Q: the contant power cables go to my car alarm, led lights, siren, power locks, power windows, and alarm bypass... they are very small thin awg wires... the ignition and constant power cables under ignition housing are alot thicker... is this possible with no problems?
confident, you're able to do this. make beneficial each and every capability twine has its own fuse close to the battery. Addressing the different solutions: this won't drain the battery any quicker than working a single twine to a distribution block; and there isn't any might desire to characteristic a 2d battery except you intend to play the gadget for long classes without the engine working.
Q: Indoor dry bag type steel core power cable terminal what is the meaning
The In general, single-core 15 square wire, for lighting fixtures; single-core 2
Q: Please, its urgent. Is it possible to use another wire? I don't have money btw.
Put a coat hanger on it and wait for a thunderstorm.
Q: The specs say: 350 Watts, DC 12V, 100-240V. It is a Rackable server.Are there special / different power cables to use with servers than desktop PCs?Where can I find the power cable with the above specs. I tried OKorder with not much luck.
You should be able to use a large three prong power cable (with a ground on it) for your server.
Q: if found the reistance then what are the acceptable limits such that replace the cable or repair the cable
See the document by Megger on how to determine if a cable is good and much more. This is a very good document that covers both static (insulation hipot testing) and TDR fault location methods.
Q: I just bought it!
Why would the power cable make noise? It's just a cable.
Q: I blew 2 fuses in my amp in my car, i have replaced them both, one was a 30amp and the other a 20. The 30 amp was an inline fuse from the battery to the amp and the 20 amp was a standard 20 amp fuse in the amp. As i said i replaced both fuses and try the amp again and it wouldnt go. There is a LED light on the top just lighting up a logo, when i attatch the power from the battery the light goes off and when i disconnect it the light comes on. When i dissconect the power the red light for diagnose comes on.
sounds like the power wire might be exposed somewhere and its shorting the system
Q: Im not very good with computers but I wanna buy Radeon hd 6850 graphic card, I have a 500 watt psu but I heard I need a 6 pin cable which my psu doesnt have. Can I use a 6 Pin PCI Express Video Card Power Cable Adapter?
Maybe. Some smaller PSUs don't have the right power rails (the way power is distributed to the wires) to do that for a power hungry card. Maybe, but I doubt it, considering the other stuff it must run. Bigger supplies have the correct wire harness for your card.
Q: I am getting a new gaming computer for Christmas with a 700 watt, 12.5 AMP (I think) power supply. I have two power cords for computers on my shelf, but my dad is worried that a standard power cable won't properly power my computer. Do I need to get a more powerful cable? If so, please send a link to where I can buy one, I have been searching but only found standard ones. Thank you.
A standard cord will work, that is not 7.5 amps it is 700w/115V=6.08amps. for 15 amps you need 14guage wire and for 20 amps 12 gauge 30 amps 10 gauge,and so on, you may need to be aware of how many other things you plug in to that circuit, such as a tv in another room or even another computer because you may have more than one room on the sam house circuit
