We know that time is precious and not everyone enjoys reading long articles, as such, we suggest you to watch the following video, however, feel free to still read our article if you want more in-depth information!
1Does my CPU need 2 power cables?
In most cases, you only need one of the EPS 8pin cables for CPU power, but in some other situations in which the motherboard has a 2 8pin or 8+ 4pin configuration, you should plug both cables in.
2Do I need to plug in CPU power 1 and 2?
You only need one to power it fine. If you want to overclock or fully utilize the auto overclocking that ryzen does not have, you should do both. When it comes to increasing voltage and clocks, the cpu will draw more power.
3Do I need both 4 pin CPU power connector?
If you’re doing extreme overclocking, such as LN2, the 4 pin is only necessary. If you’re looking for something else, the 8 pin will have all the power you’ll need.
4Do I need to connect both ATX 12v z690?
Use both of your PSU’s 8-pin EPS plugs. If not, use just the one you have.
5Can a CPU run without one pin?
If you can pin it out and reinsert it, there may be a chance of it working. A CPU may even function without all the pins, but this is extremely unusual occurrence in which redundant ground pins are removed.
If a damaged CPU is repaired and reinserted, it will work fine, but there is also the possibility that it will shorten the other pins, resulting in permanent damage to the CPU and motherboard.
6Do you need both 24 pin and 8 pin?
Yes, you do need to connect both cables.
7Will a CPU only go in one way?
If you take a look at the bottom of your processor and the socket, you will see that they only fit together in one way. On a corner of both your CPU and socket, there are also little triangles. Line everything up so it fits together and then close the socket.
To lock the lever in place, you may need to use a small amount of force. This is normal.
Now that the CPU is in place, it’s time to install the cooler. Start by taking it out of the box. On the bottom, there should be a small square of what looks like silver glue. This is the thermal paste that allows heat to sink into the cooler. If there is no square, you’ll need to buy your own thermal grease or paste and apply it yourself.
Intel and AMD coolers are a bit different. I will be showng how to install an AMD CPU. If you’re using an Intel processor, please refer to the user’s manual for instructions. Start by making sure the locking lever is in the unlocked position. Align the locking hooks with the motherboard’s location. Push the hook opposite of the lever into place. Follow the lever side down until it clicks into place. This may take a large amount of force.
8Do you need to plug in all CPU power cables?
You actually don’t. A variety of non-modular power sources will be available, but not all of them will be compatible with your computer to function properly.
9Can I just plug in a new CPU?
Yes, you can easily upgrade CPUs in Desktop PCs. You’ll have to make sure the CPU you want is compatible with the Motherboard and CPU Cooler that you already have. In addition, you may have to update some other parts to make the new CPU compatible.
10Can you run a 8 pin CPU with 4 pins?
In short, your mobo needs 8 pins from your PSU to your mobo, and 4 pins will never work.
11Do you need to use both power connectors on a motherboard?
For modern mainstream Intel and mainstream AMD, you should only ever need to plug in 1 of the 8-pins for normal use. While some boards may profit from having both 8-pins wired in for “cleaner power,” there is no concrete evidence to back this up.
Basically, if you have two on your PSU, you may as well plug it in as soon as possible, but don’t be concerned if the board has dual 8-pins, but your PSU only has 1.
However, do check your manual to see if they recommend which connector should be plugged in first. On my Unify-X, I have dual 8-pins, and it makes no difference which I use, but it never hurts to know. So:
12What is the extra 4pin CPU for?
This connector is used to supply additional 12V power to the motherboard. Although the system will likely still function without it, new demands such as extreme overclocking or large video card current draws may necessitate it.
13Do I connect both eatx12v and Eatxpwr?
Eatxpwr = 24 pin is essentially your Mobo power, and eatx12v = 8 pin is essentially your CPU power. Any board has 2x 8 pin (2x eatx12v) and with this your CPU will have more juice. However, 1x 8pin must be wired in (some high-end boards require both 8pin). So just plug both and ejoy your build.
14Why does an ATX power supply have 12V?
The ATX12VO’s design is that it ditches the 3.3V and 5V rails, leaving the power supply’s only job as to provide 12V to the system’s components. This simplifies the power circuitry layout and, in turn, lowers the component manufacturing cost.
15What is ATX 12V used for?
This is the ATX 12V or the 4-pin CPU Connector This is the 4-pin connector that supplies electrical current to your CPU and is required to connect in the motherboard if you are not using the EPS12V connector, which is described below. A vast number of processors, whether Intel or AMD, are using the ATX12V 4-pin connector.
