Q: Hi. I was snaking 40 feet of underground burial power cable thru a PVC conduit. As I did not have any cable pulling lubricant, I used JOY dishwashing liquid detergent as a lube for pulling the cable with a snake. Will that damage or detiorate the outer jacket of the cable it is still in the conduit. The flexible conduit I used is water tight and I have plugged both openings with silicine caulk.
It'll be ok for about 5 years. The chemicals will eat through the outer casing which is more resilient than the inner insulation. Next time, go to Lowe's, Home Depot and purchase some Wire-pulling lubricant.
Q: Hi,I have an LED monitor ordered and I wanted to know if it has a power cable. The monitor I ordered is a Samsung S23C350HS 23 Inch Screen LED-Lit Monitor. Thank you,
No question about it a monitor whatever the make will have or need a power cable there have not been any monitors made that can recieve enough power from any other lead connected to the computer
Q: I have my Clearwire modem but have lost the power cable. Does anyone know what I would look for in a replacement power cable.
check the Clearwire URL .. Support tab
Q: Would a maxtor 320GB external hard drive work without a power cable if I connect it to the USB port?
you could make it work if you are planning to make a usb cable for power and another one for the receiving and sending of data. but if you are meaning to just plug in the usb cable from the hard drive to a port then no you can't a usb is ussually 5V and i don't think that's enough to power up a hard drive. just buy a power cable they aren't that expensive. if you have enough money to buy the external hard drive you wouldn't mind spending 5-10 dollars for a power connector.
Q: i have a cable modem that i lost the power cord to. i found another that fits but the output listed on the adapter is 12.5vdc. the modem lists +12vdc. can I use them together? i plugged it in and it lit up for a while but then went out but I don't really know how the modem is supposed to work if there's no internet connected to it.
first! are you sure the modem needs 12 V DC and not 12 V AC? Mine uses AC. OK, you can use a 12.5V in a 12V modem - the extra .5V is not a problem... Next, make sure the polarity is correct!! center pin is the correct polarity? If not, POOF! You will let the smoke out. Have you considered that the modem is bad and the power supply is not the problem here. If the modem is bad, you may have killed the supply you plugged in.
Q: Im going to get a new graphics card. I am getting the XFX Geforce 9800 GT and it needs 1 six pin PCI Express power cable. It comes with a cable to convert 2 molex cables into 1 six pin pci power cable. Problem is, is that dont have any molex cables available. I have 4 SATA power cables. So if I got a converter to convert 2 SATA power cables into 2 Molex cables into 1 six pin power cable work? Would I lose any voltage/ watts? Please let me know, I got the graphics card for christmas and I dont want to end up with it not even working.
I okorder ) And no, it won't work. The PCIx power is drawing from a different part of your PSU than the molex is. Send me an email, and we can talk about upgrading that PSU. If we figure something out, I'll edit the post on here to reveal our findings. Cool?
Q: The only thing that im worried about is that my PC power cable has three little slots where you plug it into the brick and my brick only has 2 slots, th cord still fits and powers up my xbox 360 but im just worried about it quot;fryingmy new system. Thanx
i'm sorry, yet it rather is an somewhat unusual question. Why could it no longer be secure to plug something right into a surge protector? Are there contraptions obtainable for which an electric powered surge is a good factor? No, i easily do no longer think of so. unusual.
Q: i have a SATA hard disk and i connected it with a sata power cable and recently i bought a sata optical drive and i have no power cable for connecting the drive, so i decided to connect it with the power cable of hard disk(I have two sata hard disk)
while you're meaning are you able to boot off of the IDE annoying force and get entry to the Sata force, the respond is sure. in basic terms connect the SATA annoying force, and make beneficial the BIOS settings are set to boot from the IDE force.
Q: as far as i know, the only cable that connects the hdd with my motherboard is the sata cable, is this the cable that will do both transfer data and also provide electricty? or do i need another cable to connect the hdd and to power supply? same for my sata dvd burner, thx!
That all depends upon the present cable and the slots to which it is connected to.
Q: I'm getting some upgrades for my pc and that includes a new power supply with the necessary amperage and 2 6-pin pci-e connectors to power my card. The card is already here but the psu probably won't get here until next week. I want to know if there is any way to run the card from the power coming from the pci-e slot. The card requires 2x 6-pin connectors, but i want to install it now to get that out of the way...
You can but the system will be very unstable, that's even if it boots at all.
