Quick Answer: Where Does The CPU Cable Go?

How do you check your PC power supply?

The AnswerPlug the power supply into the wall.Find the big 24-ish pin connector that connects to the motherboard.Connect the GREEN wire with the adjacent BLACK wire.The power supply’s fan should start up.

If it doesn’t then it’s dead.If the fan starts up, then it could be the motherboard that’s dead..

What is the PCI E cable for?

This connector is used to provide extra 12 volt power to PCI Express expansion cards. Many video cards draw significantly more than 75 watts provided by the motherboard slot, so the 6 pin PCI Express power cable was created.

How does the CPU get power?

The CPU does not receive power from a cable. Its power comes from the socket on the motherboard. … If so, your motherboard and case are getting power.

How do I overclock my CPU?

The only reliable way to overclock your system is to change the settings in the computer’s BIOS. The BIOS (sometimes referred to as UEFI) contains the PC’s key settings. To access the BIOS, you must turn off your computer and turn it back on.

Are CPU and PCIe cables the same?

3 Answers. They are completely different. The EPS connector is meant to supply power to a motherboard cpu socket while the PCI express connector is meant to supply power to a GPU.

Where do I plug in my graphics card power?

The cable on the right plugs into the 6-pin port on the graphics card. The other end of it has 2 3-pin power connectors. The middle and left cables plug into the 8-pin ports of the graphics card.

Is it safe to use Molex to 8 pin?

Yes, using an adapter is safe. From personal experience I didn’t have the correct PCI-E cable so I had to get an 8-pin adapter to power up my MSI GTX 970.

What makes a CPU fast?

A computer’s processor clock speed determines how quickly the central processing unit (CPU) can retrieve and interpret instructions. This helps your computer complete more tasks by getting them done faster. Clock speeds are measured in gigahertz (GHz), with a higher number equating to higher clock speed.

How efficient is a CPU?

If you’re talking in terms of their power efficiency, the figure is around 70%-80%. For example, my processor draws roughtly 200W of power, and dissipates about 150W. That’s 75% efficiency, an estimate, but pretty close. If you’re talking in terms of their power efficiency, the figure is around 70%-80%.

What is the CPU power connector?

Nowadays it is the P4, or EPS connector, to provide the cpu with power. Cheap motherboards are equipped with a 4-pins connector. More expensive “overclocking” motherboards have 8-pin connectors. The extra 4 pins ensure that enough power can be provided to the cpu when overclocking.

Where does PCI E cable go?

Every modern-day graphics card comes with a PCI Express x16 connector that goes in the PCI Express x16 slot of your motherboard. PCI Express x16 connector connects your graphics to the motherboard and is the only interface through which communication happens.

Can I put a 6 pin PCIe into an 8 pin?

Lifer. All the 12VDC pins on both the 6pin and 8pin connectors are connected on the video card so it doesn’t know the difference. The reason for 8 wires vs 6 wires is because as current increases you need larger wire. They could do it with 2 wires but then the wires would be larger and harder to maneuver in the case.

How do I connect my 8 pin CPU?

How to Connect PSU CablesConnect your power supply cables beginning with the 24-Pin Motherboard connector.Next, connect the 8-Pin CPU/ Motherboard cable. … Next, connect the 6 or 8-Pin PCI power cable to your video card. … Next, connect your storage or disk device such as your HDD, SSD, or DVD Drive.More items…•

Where does the 8 pin connector go?

8-pin goes to PSU and 6+2 goes into GPU. There is usually a label on one side that says what it should go into but not always, just a little surprising though.

What cables do I need for my PC?

Computer Cable types and descriptionsVGA Cable. Also known as D-sub cable, analog video cable. … DVI Cable. Connect one end to: computer monitor. … PS/2 Cable. Connect one end to: PS/2 keyboard, PS/2 mouse. … Ethernet Cable. Also known as RJ-45 cable. … 3.5mm Audio Cable. … USB Cable. … Computer Power Cord (Kettle Plug)

Is a 6 2 pin the same as an 8 pin?

The only difference between 6+2 and 8 pin is the fact that you can detach the other pins for compatibility with 6 pin PCI-E devices. There is no electrical difference between 8 and 6+2 PCI-E cables.

What is 8 pin PCIe?

This connector is used to provide extra 12 volt power to PCI Express expansion cards. … These are sometimes called “PCI Express cables”. They are also occasionally called “PEG cables” where “PEG” stands for PCI Express Graphics. 8 pin PCIe power connector at the cable. 6+2 pin PCIe power connector at the cable.

Can you run a graphics card without a 6 pin?

The graphics card needs the additional power, and no, it won’t run without it.

How much power does a CPU use?

Most computers are built to use up to 400 kilowatts of electricity per hour, but they usually use less than that. The average CPU uses about as many kilowatts per hour as the typical light bulb. Any computer that’s running on a Pentium-type processor uses about 100 kWh. This is with the monitor off.

How do you plug in a CPU?

Plug the 24-pin power connector into your motherboard first, then go for the 4 or 8-pin CPU power connector. Plug in the optical drives, SSDs, and hard drives. Finally plug any required PCI-E power connectors into your graphics card, then double-check all of the plugs to make sure they are securely seated.

Can I use PCIe cable for CPU power?

No! Don’t do it! You will destroy the motherboard and PSU if you plug a 6+2 PCI-e connector into the 8 pin CPU power connector! The PCI-e connector has 3 12V lines and 5 ground lines, the CPU power connector has 4 12V, and 4 ground, you will have a direct short between 12V and ground if you do that.
