    1Do I need both 8 pin CPU power connector?

    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:


    2Do I need both CPU power slots?

    You need both to run the board. It has 18x 75 amp power stages. Without both EPS connectors, the board will not be able to post.

    3Do I need both the 8 pin and 4 pin CPU power plug?

    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.

    4How many pins does the i9 12900k need?

    24-pin connector for the motherboard.

    5Do I need both the 8 pin and 4 pin CPU power plug for my MSI b450 Pro Carbon?

    It’s enough to install the 8 pin connector on the left from experience. The right 4-pin connector is basically a redundancy that the CPU can rely on under extreme load, and it is likely only relevant when you do extreme overclocking.

    6Do I need to plug in the extra 4 pin CPU power?

    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.

    7Can I use a 4 pin in a 8 pin motherboard?

    In short, your mobo needs 8 pins from your PSU to your mobo, and 4 pins will never work.

    8Is 8 pin enough for Ryzen 9 5900x?

    If you aren’t OCing, you’d probably be fined on a single 4 pin, so an 8 pin will be peachy.

    I have a 220W 20 + 4 pin ITX PSU that i use for testing purposes on occasion, and i’ve never had it fail to post on 24/8+4 systems.

    9Do I need to connect both ATX 12V?

    Yes, you do need to connect both cables.

    10Does Ryzen 5900x need extra 4 pin?

    You do not need another 4 pin. When you take out the Powerlimit and then run P95, you won’t even need more than a 4 pin.

    11Can I use PCIe cable for CPU power?

    No, it’s not possible to use a PCI-e cable to power the CPU. Do not do this because doing so will shortcircuit the entire system and also permanently harm the device. Both PCIe cable and EPS appear to be the same, but have different power factors.

    You’ll have to deal with various types of cables when building a desktop. Since they all have different types of construction, different brands of cable are used for different purposes. For example, the SATA cable is used to wire the motherboard and the HDD.

    However, there are two similar-looking cables: the PCI-e 8pin or 6+2 pin, as well as the EPS cable. They look exactly the same. You can’t tell if there are no markings in the cable head.

    The PCI-e connector has three 12V lines and five ground lines. On the other hand, the CPU power connector has 4 12V lines and four ground lines. So there is a direct shortage of 12V. So, if you’re trying to connect the PCI-e cable to the EPS slot, then you’ll connect a Ground line in the 12V line.

    So if you do this, the CPU will not be able to respond in the majority of cases.

    12How much power does 8-pin CPU provide?

    A single 6-pin connector allows for 75W power delivery, while a single 8-pin connector allows for 150W power delivery.

    13Is an i9 overkill for gaming?

    Both the i7 and i9 series of chips are a bit overkill to argue for their higher price points relative to chips in the i3 and i5 brackets.

    14What power supply do I need for i9-12900K?

    A 700W PSU will fit a 700W PSU, with the EVGA SuperNOVA P2 delivering high performance and a completely modular layout to prevent cable-related mayhem inside your case. To power some of the best graphics cards in the PC game, stick to 750W and above.

    The be quiet! The Dark Power Pro 12 can handle up to 1200W of incredibly fast 80 Plus Titanium-rated performance, ready for any GPU you choose to pair with the Core i9-12900K Alder Lake chip.
