1Why does my PSU have 2 CPU cables?

Sometimes one of the cables can be split in 2 CPU 4 pin connectors, perhaps explaining why it says in smaller letters on a cable. This makes it possible to power a motherboard with only one 4 pin CPU connector or motherboards with just one 4 pin connector.

2Do you have to plug in both CPU power 2?

If you have two, connect two. The extra 8 pin connector can be used to power up cards in the pci slots as well as increased clock speed for overclocking. In testing, I used only one which worked fine.

3Do I need both 8 pin CPU connectors?

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:

-No

4Do 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.

5Can 8 pin GPU run on 6 pin?

No you can’t. The GPU has 8 pins and will expect an 8 pin plug. You can convert your 6 pin power into 8 pin power, however, using an adapter like the one shown below. If you do this, be aware that you are sucking more power from the 6 pin rail than it is actually intended to handle.

6What is the CPU power cable for?

The processor socket is mainly responsible for the CPU power connector. Both PCIe cable and EPS cable are labeled for the same look. Otherwise, it will be impossible to tell the difference between them. The pins are mainly due to different power requirements.

Nowadays, EPS cables differ in terms of PSU. Here are some examples of EPS cable you may have seen in the market 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+4-pin Or 8-pin+390W, etc.

7Do 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.

8Do 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.

9Do I need to use all CPU power connectors?

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.

10Do I use both CPU power headers?

If you have two power headers for the CPU in the board it’s best to use both if you can but again, DO NOT try to use what’s for the GPU (PCI-E power plug) in these slots or the other way around – You’re just asking for it when you mix those and you’ll get it too.

11Is 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.

12Can 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.

13Is 4 pin enough for CPU?

In order to use the motherboard, the 8-pin ESP is required. Since the CPU is not capable of drawing enough current, you will not need the extra 4-pin ESP connector for your CPU.

14How 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.

15Does 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.
