Q:My power supply cable to the motherboard is only 20 pin and the motherboard has a slot to take a 24 pin power cord. The 20 pin will fit but 4 slots are just left empty. The motherboard LED light comes on showing it has power. When I try to boot up the motherboard runs but the hard drive doesn't boot or the screen isn't working. Could this be b/c of not having a 24 pin power cable?I know the video card and HD work b/c I just transfered them from another motherboard that was a 20 pin. Any ideas?

I believe it'll work, 4 pins will just hang off to the side. The same goes for 8 pin power cables to a 4 pin power socket on the motherboard.

Q:I mean like the power connector cables. All power supplys have the same cables to supply power from the PSU to components right?

not all PSUs have the same cables but they do all come with the same standard connectors. for example all PSUs regardless of wattage and brand will have the 4 pin molex conectors but not all will have the 6 pin and the 8 pin PCIe connectors and the higher end models will also come with 2 CPU 4 pin power connectors. which PSU you get depends on wattage demand of your system, amperage demand if you have a video card requireing extra power and the number of molex/sata power cables and PCIe 6/8 pin connectors you need.

Q:i have a ASUS M4A87TD-USB3 mobo and a Corsair 550 Watts Power Supply. Ive looked in the manual andit says you need to connect the one that ive connected and a 4 pin. It says that if you dont connect the 4 pin the computer wont boot! is there a way around this or it f**ked?

Just replace the power supply. What's the problem? You have an OLD ATX powersupply with 20-pins. The NEWER ATX power supply is 20+4 pins. --- Kasey C, PC guru since Apple II days Make it idiot proof and someone will make a better idiot.

Q:im curious what a good rule of thumb would be for determining how strong a fuse to put in line to the amp. im getting a 2300 watt amp but dont know how many amps of fusing it uses. so i dont know its power draw. any help would be great

current(A)=power(W) / voltage(V) go with Jeffs answer so you can blow them all-idiot do the math! 2300/12=191A! How hard is that!

Q:YJV three-core cable and the difference between the four-core cable

Q:Hi, Recently I bought nikon S550 digi camera from U.S, their power supply is different from India. In the power cable they mentioned 125 7A, do i need any convertor or directly i can use.

India power outlets run 220v, not 120, so you are going to need a converter or a completely new power-supply.

Q:How can i fix it and how much would it cost?

Well... It depends. First things first, never move your laptop with the ac plug connected to the laptop. This is why the plug stopped working. The connection is very fragile, it cannot withstand very much abuse. To get it fixed, you would have to bring it to one of the local computer repair shops to have a new AC jack soldered to the board. You will probably have a hard time finding a larger repair shop that will do this for you. You would be looking at around $120-180 just in labor. The jack will probably run around $10.

Q:Can anyone help? my pc wont turn on without them hooked up.

If you look very close the position for these connectors is written on the motherboard along side of the pins that they connect to in very small letters.

Q:Hi, Whether it will causes any problem the power and speaker in a same path? I dont have a separate path for speakers to mount it in wall. I plan to use the existing path which is used for other electrical items. If i use the same path for electrical wire and speaker wire, it will damage the speaker or will make any short circuit in the electrical line?Thank you.

If you parallel a power cord, you could get 60 cycle in the speaker cord. This is why they would like you to run them at least 4 apart. However, you might not be able to do that. It will not damage the wire, nor create a short circuit. Just possible noise (a low frequency buzz).

Q:When wiring a power cable to your car battery, should you always put a fuse close to the battery or does it matter if you don't use one?

you don't have to but its highly suggested you do, it will save your amp if anything happens
