Q: So, I built my first computer 6 months ago, only to have the power supply fail, and maybe fry the CPU or the motherboard (hope not), and I ordered the XFX 550W from newegg. Now I built the computer, but this is actually going to be the first time I'm taking out the cables of the power supply to the motherboard, and it looks like it's quite tightly in there, do I just take it out by force? I don't want to exert too much pressure because I'm a pussy and I don't want to ruin it haha.: Hi, There is often a plastic clip holding the connection in place, check for that first then pull gently as they are not normally that tight. Arnak

Q: I have a 2003 hyundai tiburon and need to know where in the firewall should i drill my hole to run the power cable i know it goes throught the firewall but where if you have ever done this to a tiburon please let me know.: Sometimes there are unused holes plugged with rubber stoppers. Otherwise, locate an object coming through the wall for a reference point.

Q: I bought this graphics card tonight, and went to install it on my new Dell PC and while the card itself is powered by a 6-pin, I don't have one on my power supply. Is there an adapter I can use? Or will I have to go buy a new power supply for a NEW computer..?: Depends - what are your system specs? Impossible for people to help you when we don't even know what hardware you're running. Don't ruin your new graphics card by putting it ; 1. On a power supply without enough wattage to handle it, and 2. On a power supply that didn't come with cables for a graphics card. Chances are you should invest in a bigger power supply. I would recommend at least 550w for a GTX550Ti. I recommend Corsair and XFX power supplies, as well as Seasonic.

Q: Hi, Im building a computer and my Power supply dosent have enough Cables/wires for all the slots. We do have enough to fill one motherboard power slot and we also have enough to fill about a hal of one. Can my computer run with just half of one of the slots? Also, my computer's Graphics card, a Gigabyte GV-N560UD-1GI nVidia GeForce 560 Ti, has two power slots, and the wires that it comes with have 2 4 pin peripheral power cables brnching off of it. My power supply only has enough to fill 1 of the cables. My dad says it will be fine but i dunno. Please awnser quickly! Any awnsers will be much a preiciated: for the GTX560 Ti Here is what your APEVIA ATX-TL450W 450 Watts has: Those are for your motherboard: 1 x Main connector (20Pin / 24 Pin) 1 x 12V(4Pin) Those are for SATA and Molex HDD, DVD 3 x peripheral (aka Molex 4 pin) 1 x SATA Plus 1 x Floppy which no one uses anymore Your only solution would be to buy a newer, better power supply, which is what I recommend. Or, as a compromise (not recommended, as your power is not big enough for all components). Use 2 Molex to PCI-e cable adapters to power your graphics card. Use 1 Molex to SATA to power your DVD drive Use the only SATA to power your hard drive. Good luck.

Q: i bought a 650w power supply for my pc because i bought a graphic card that needs 550w. So my question is will my regular power cable which came with my computer work on the new 650w power box.P.S- my computer is a 300w: Yes. it is the same cable that comes with every computer, printer, monitor. OK it's the same cable that comes with 95% of them

Q: We found a flat screen HD monitor in someone's trash can and we just need to find the cables. I searched online for cables for this model and can't find any. I just need the power cable for it and the DVI cable.: try radio shack.

Q: I just bought the 8800gt, but i don't have the cable to connect it to the power supply.So what cable do i need ??I found those but i am not sure: If you want to find out what cables you need there are two ways. 1. check the manual or guide that came with the device to see if it says what cables you need. 2. take the device with to a hardware or electronics store and ask the clerks there to help you find the right cables for you're device.

Q: Hello, I am looking to purchase a single power connector for 5 hard drives. I have a modular 1200W power supply, and all i can find on website is these single power connecters that do not even look like they will connect to my power supply. My computer came with power connectors for 4 hard drives in single cables. I do not want to waste another Power supply slot for just 1 more hard drive. Can anybody tell me how to search for this? Thank you.: I do not want to waste another Power supply slot for just 1 more hard drive. That's what they're there for.

Q: Hi,I have problem with power cable on Karcher 670m pressure washer. I pulled all of the power cable out and now it's stuck and doesn't roll back inside. What can i do to fix it?Sven: Throw the piece of crap away. Just kidding, but it wouldn't make sense to take it to a repair shop when you could buy a new one for $100 bucks. Just roll the cord up when your finished using it.
