Not all pins are needed in a given configuration.
Another possible scenario would be if your motherboard requires a 24 pin adaptor and the power supply only has a 20 pin interface. In this situation, the 20 pin could be plugged in and might provide adequate power to operate the basic components to make the system turn on and run. However, you will have power deficiencies most notably to the CPU. This could in turn be harmful to CPU, motherboard, power supply, etc. by components demanding more power than the available conduits can provide.
When a computer is plugged in it usually comes on right away to show you that everything is connected correctly. If it doesnt come on than you could have an electrical problem where not enough voltage is reaching the power supply.
The OCZ StealthXStream is a great camping power supply.
a computer power supply (PSU) provides poer to all the components in the system and makes sure they they do not too much power to overload them or not enough to cause them to shut off
Possibly not enough output power. Are you sure that you got the right size power supply?
The mother board, power supply, and chassis
Yes, provided that the power supply is big enough to handle the extra drain AND provided that you have enough space and connections. Those restrictions are all based on what the manufacturer put in the computer.
I am not sure why 2 things... What you need is powerful enough power supply, enough space in your computer case and good ventilation to prevent overheating. And a compatible interface.
If there is not enough supply for the demand, the demand won´t be able to buy the supply
If it is a computer power supply it is the box that gives the computer its power from the outlet.
In order to supply power supply to your computer you would need an outlet plug near your computer. Then you can plug your computer into that and necessarily, use an extension.
No most home speakers are supposed to be powered through an amplifier. A computer will not supply enough power to effectively run those speakers. Plus the wiring for computer and home speakers are very different.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
