Best Answer

Many/most motherboards have a separate power connector for the CPU. Check your motherboard's installation instructions to locate the CPU power connector. Then connect the matching power supply cable to the CPU power connector on the motherboard.

Is CPU a peripheral device?

No, peripherals are things like monitors, keyboards, mice etc. CPU is a major component that a computer must have to operate. It is a processor, all other parts are peripherals. (Some computers, some severs for example, do not need any peripherals to operate.)


What does the CPU connect to?

The CPU is connected to all the peripherals, which include the keyboard, the monitor, the speakers, and anything else that is connected to your computer. Strictly speaking, the CPU is physically connected to the motherboard.


What is bus architecture?

Bus architecture is the pathway between the CPU and other peripherals. It is usually a shared input/output pathway. Bus is short for omnibus, which means, for all.


What are the function of registers in microcomputer system?

The function of registers is the same in all computers. They are the fundamental binary interface between the internal and external structure of the CPU. All binary transactions between the CPU and its peripherals pass through registers. From the inside, they are the final periphery to the pins.


What is a motherdboard?

I believe you mean a "motherboard". This common computer hardware connects the central processing unit (CPU) to all of its peripherals (input, output, signaling, and storage devices). It is also responsible for drawing power from the power supply unit (PSU) and distributing it to all of the integrated circuits (ICs) that are attached to it. Permanent and removable media devices typically draw their power directly from the PSU, while the motherboard routes power to USB devices, input devices, CPU, RAM, and the various IC chips and addon modules (such as PCI and ISA buses) that operate from the power matrix that the motherboard supplies.


Do you have to install the CPU before trying to power on the computer and see if the fans work?

Yes. you cannot start a computer without a CPU, or at least you should never try to do that, cause im sure something is going to go wrong. Install motheboard in case first, then CPU, then ram, then CPU fan, then power supply,then harddrives and disk drives, then make sure all wires are connected, including fan wires. Now you can start your computer.


What is wrong when my CPU does not respond no front panel light's the fan is running and monitor is blank?

If the PC powers on and performs no bios or mainboard functions (nothing comes up on the monitor screen, the monitor remains in power save mode) then the CPU may not be receiving enough power, or the CPU may have burned out. Check the power cables going to the mainboard, and or contact someone who can troubleshoot your PC. Power cables are good checked them, mainboard is good too, it you reboot it all comes back up.


What is the function of the control unit in the CPU?

The control unit provides the timing and control signal to all operations of microcomputer. It control the flow of data between microprocessor and memory and peripherals.


Can you buy a adapter to connect 1 monitor to CPU?

You need a graphics card for a monitor and this card needs a cpu, a cpu needs ram and a motehr board. all need a power supply. and all this together is call a computer.


How can you tell if your power supply or CPU has gone out?

Pull out CPU and turn on your computer, if you hear BIOS error complaining about CPU absence: most likely your CPU is dead. Also try to test power supply harness. All required wiring diagrams and standards you can find in internet, just use google.


What are different point s between microprocessor and micro-controller?

Microprocessor = CPU Microcontroller = CPU+peripherals+memory A CPU cannot run independently, it needs peripherals and memory circuits. In embedded systems microcontroller designs are easier than microprocessor design. For example 8051 controllers will have EEPROM, RAM, timer circuit, serial port, SPI, GPIO, etc. If ur application need not have all these, just EEPROM, RAM, GPIO is enough then u can go for 8058 CPU with 8055, EEPROM, RAM. In otherwords CPU designs may provide more flexibility to ur Embedded design. whereas microcontroller designs can make designing easier. Hope this may help u !!


What is the importance of plugging the CPU and other computer peripherals in the Automatic Voltage Regulator and not directly to the power source?

Because in laymens terms, the regulator provides clean even distributed power throught everything that is plugged into it. You never want to plug into the source with any kind of tech. For the simple reason of power spikes failures and "dirty power" that can harm your tech in anyway. For more info check the link for all the info you would ever want on power supplies and why they are used.
