- Q: So here is the power supply, motherboard and graphics card I have.Power Supply: ATX-TL500W-BK Motherboard: GA-78-LMT-S2 Graphics Card: GV-N960XTREME-4gd As you can see the mother board is a (pcie 2.0), and my graphics card is 3.0 with a 6pin and 8pin slot on the side for It's power cables.My previous graphics card didn't need any cables to run to it, so I don't know what I need for going from the 3.0 to the 2.0, and I don't know where the power cables for the card connect to.Any help is very appreciated.
- You have a big enough PSU--400W recommended, you have 500W available. The cables from the card go to the PSU. If you don't have the right one(s) then buy adapters. Contact card maker for those if you didn't get any in box or search Google.
- Q: Recently I bought a EVGA Geforce 8800 GTS. When it came in, the card fits in my case but has 2 cables to plug in. I only have 1 cable to plug them in connected to my power supply. Should i only plug in 1, or is it nessesary? Is there an extra one I just dont know about? Please answer!
- After looking at several 8800GTS's online, I don't see any that require two PCIe six pin plugs. This means I think your talking about the 4 pin molex adapter to be used by those that lack a 6 pin PCIe plug. Because this is a powerful card and it can't get enough electrical power to run from the socket, it needs more juice, and it gets it from the 6 pin PCIe power plug found on newer PSUs. For people that don't have that, many places include an adapter that you can use. If you don't have enough open/free molex plugs however, I question whether or not your PSU has enough power to feed the 8800GTS. What PSU do you have? How many Amps are on the 12V rail? Open your case up and see if you can read the sticker that should be on all power supplies. If you don't have enough open plugs, I would NOT use a splitter. Splitters can be used to hook up several low power devices (like fans) not high power devices like video cards.

- Q: I have vtech 5.8 phones that you plug in to the electric socket. It is also connect to the internet.So if the power goes out so does the phone. What phone can you get the will work if the power and cable goes out
- plug your phone into the UPS on your computer. This will keep the phone working for a couple minutes, but the internet access may go away too. What you need to keep the phone working is a traditional land line, a traditional phone used for power failure. Even in big businesses that use a PBX or eKSU, we install power fail phones. SOME Vtech phones have a slide out drawer in the base unit where you can charge a battery. This will keep the base unit working without power.

- Q: Cable bttz-4 * (1 * 50) and bttz-4 * 50 What is the difference
- What is your video card? First must be a separate graphics card. If it is the result of the accumulation of porcelain porcelain puzzle, you give up it. Use the DVI interface to connect the computer monitor, connect the LCD TV with HDMI, in the graphics driver settings to nVIDIA graphics card, for example, install the driver, enter the display attribute drive settings interface, click the expansion window "nView", in the "nView Mode ", you can set to" copy "," horizontal span "or" vertical span "as needed. "Copy" means that the contents of the two displays are exactly the same. "Horizontal cross" means that the display of two monitors is connected in the horizontal direction, for example, we want to work in the main display, but also want to watch movies in the auxiliary display, which is a more applicable function.
- Q: Will it work if I put a pigtail (connect the wires by twisting them together) or does that stop it from working properly..
- Unplug it, get rid of the battery. Then carry the potential button for 10 seconds. Reinstall the battery, plug it in and charge the battery without using it until eventually it is totally charged.
- Q: I have a HP Printer and have lost my power cable, now I am having trouble identifying the type of lead that goes in the hole (see pic link)I am in the UK
- Cada día tengo algo para imprimir o fotocopiar y por esto decidí que ya está la hora de comprar una impresora, después de todas mis buenas experiencias en OKorder estaba segura que, y de esta vez, voy a encontrar lo que busco, la impresora multifuncional que me he comprado cumple todas mis expectativos, ella me he hecho mi vida mucho más fácil.
- Q: My power cord for my computer and all usb cables i have seen have these cylindrical things on them. What do they do?
- Those devices are for supressing RF interference to external devices. The high data rates, tend to create signals just like transmitters, which can interfere, with you TV, cordless phone, stereo system, etc.
- Q: I have a usb hub that is externally powered that stays on 24/7 even when i shut my computer off. It is buried behind by desk so removing the usb power supply manually each time is what im trying to avoid. Is there anyway i can put a switch in the power cable going to it?
- Before you attempt this, make sure you have the following items: -Wire strippers -Electrical tape -Two terminal switch -Scissors IMPORTANT! make sure that the cable is unplugged from the computer and the hub before you do this! 1st, cut the cord halfway with the scissors. Next, remove the outer wire insulation from the two new ends you just cut with the wire strippers. Now strip the small colored wires that are now exposed. Then connect the red wire from one half of the cord to a terminal on the switch. Do the same with the other red wire from the other half of the cord and connect it to the other terminal on the switch. Strip the other small wires and connect them back to their appropriate colored wire. Finally, wrap each wire individually with electrical tape, then wrap the entire gap in the cord with it. Now plug the cord in and try it out!
