    1Do I have to use both CPU power ports?

    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.

    2Do you need to plug in 2 CPU cables?

    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:


    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.

    5Will 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.

    6Can you run a PC with 2 power supplies?

    Secondary Power Supply Unit adapter. Add a second PSU to your PC. To add more power to your computer components without having to upgrade your existing Power supply unit, connect two Power Supply Units together to bring more electricity to your computer components. Your computer will need enough space to hold two PSUs.

    7Do you need both 24 pin and 8 pin?

    Yes, you do need to connect both cables.

    8How many CPU cables do I need for PSU?

    Almost every PC’s power supply will have an 8-pin connector that breaks in two, also known as a 4+4-pin. This allows it to be connected to both 4-pin and 8-pin connectors, so you can leave one of them at home if you don’t have to use it. You may find more than one CPU cable in some power sources.

    9Do I need both 8 pin GPU power connector?

    6+2-pin and 8-pin Power Connectors Some graphics cards require just a single 8-pin connector. Others, however, need two. Others still get their power through a 6- and an 8-pin connector (300W in total).

    10Can CPU work without some pins?

    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.

    11What is the extra 4 pin CPU connector 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.

    12Can 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.

    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.

    14Do I need to connect all ATX 12V?

    If the 12V power connector is not connected, the computer will not start. To meet expansion requirements, it is recommended that a power supply that can withstand heavy power consumption be used (500W or greater).

    15Do I need all the cables from my power supply?

    Do I have to connect all of my power supply 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.

    You actually don’t.
