Q:I installed a second DVD/RW drive on my computer, but I only plugged in the data and power cables, READ MORE?
Are your drives IDE, SCSI or SATA? If they are IDE, are the jumpers set correctly for master/slave or cable select?
Q:HP Pavilion dv9500 power cable broke?
Contact HP, this laptop was designed for Vista so more than likely there are no drivers available for xp.
Q:What is the installation specification for the cable tray bracket?
In accordance with the requirements of the general requirements of the installation of the switch installation height is 1300mm, the socket is 300mm, air conditioning socket is 1800 ~ 2200mm; wall in accordance with the norms is not allowed to take the horizontal pipeline, so the conventional approach is vertical inside the floor of the pipe is near run.
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
I have to integrate a graphics card, you buy a separate graphics card is really a waste of money now I also listed, showing a lot stronger than the 2100 performance, and the market in the low-end discrete graphics upstairs you upstairs a lot of results Even a display did not give people with the price exceeded
Q:Why do power cables have a big sag in the middle?
Gravity okorder.com/
Q:The lights in my room goes out when I take out the power cable on my PS3?
Bad wiring in the house? Sounds at least like a situation like that. Not uncommon in buildings of certain times.. older types of wiring used. And worse not ready for todays amount of electronics. So yeah check the wiring. In between time buy a few extension boxes, you know the type with more then 1 electronic socket. But most important a switch. That way you can switch it off and that way such discharges won't happen any more.
Q:Connecting jumper cables to power inverter cables (mini jumper cables)?
That's fine for a temporary use situation. However, if you are going to be using this regularly in the same vehicle, I would recommend a more permanent installation using 4 ga power wire directly to the positive terminal of the battery. Make sure you install a fuse on that wire as close to the battery as possible. If the jumper cables are cheap and thin, or the contacts are coroded or not making good contact, this can cause the voltage to drop to your inverter and cause it to draw more current and possibly fry the power supply.
Q:sata power input?
No, there is a separate power cable for SATA devices - the same as PATA devices. Interestingly enough, the SATA cable is 7 pins, and the power cable is 15 pins!
Q:What power cable can I use for Fender FM15 DSP Amp?
Looks OK for the price.
Q:Can you use any power cable with any amp?
It means that it has 300 watts of power . Thats a lot of power. 120VAC means that you connect it to a regular wall plug. If you can connect it to the amp and the wall socket , you got yourself an amp.
