Our power supply units (PSUs) use an 8-pin EPS12v CPU cable that can be split into two 4-pin connectors. If you want to connect our PSU into a 4-pin EPS motherboard port, simply pull the two halves of the connector apart and connect one half into the motherboard port.
Can I use a 8 pin power supply on a 4 pin motherboard?
As with plugging a 24 pin cable into a 20 pin motherboard connector, you can plug an 8 pin cable into a 4 pin connector and leave 4 pins hanging over the end but you can also have the same problems with things preventing it from fitting. It will work fine if it fits.
Do I need both the 8 pin and 4 pin CPU power plug?
The 4 pin is only necessary if you are doing extreme overclocking, such as LN2. Otherwise the 8 pin will provide all the power you will need.
Is a 4 pin to 8 pin adapter safe?
Typically no, it’s not considered safe to use a 4-pin (molex?) to 8-pin PCIe adapter. Adapters are not standardized and can use thin gauge wire that can melt if too much power goes through them. It’s worrisome that you say 4-pin to 8-pin, because the 4-pin connectors are for the CPU and cannot be used for a GPU.
What is the 8 pin CPU power connector for?
Each 4-pin EPS 12V connector can deliver up to 75W. This means that with an 8-pin power connector, your CPU has access to up to 150W of power.
What is the extra 4 pin connector on a motherboard?
The “X” AM4 Motherboard has an additional 4-pin ATX power connector but the “Y” Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking may require it.
Do you need 8 pin CPU power connector?
You have to plug in the 8pin connector. If you’re going to overclock the cpu plug in both. If you’re not just the 8pin connection.It’s definitely not needed for normal operation or even a slight overclock.
Is PCIe and CPU power the same?
Yes, as they both provide 12 V. Also You can see it on description of those ports, if they have common description of “CPU/PCI-e” then You are sure that there will be no problem. As You can see in above photo those ports are interchangeable and have the same connector outlay.
Do I need both 8 pin GPU power connector?
Some low-end and mid-range graphics cards can only use the PCI Express x16 slot as a power source, but more demanding cards will need to use 6-pin or 8-pin PCI Express power connectors.
Is 6pin to dual 8pin safe?
It’s just a plug. The only thing that matters is what’s on the other end, namely 2x 6pin pcie. Those can be adapted to a 8pin pcie, but don’t try using that board connector.
Can I use a 6 pin on a 8 pin GPU?
Yes, you can use a PSU that has one 6 pin and one 8 pin PCIe power cables for connecting to a GPU with two 8 pin sockets using an adapter like this: or this: BUT, be sure that your PSU (power supply) has enough power on the 12V rail to support that much power.
Is it safe to use Molex to 8 pin?
there are other similar adapters that combine the power connectors of a couple sata/molex plugs into a single 8 pin. Simply put, you’re on the edge – if it’s a very high quality 450 W unit, it will indeed run the RX 570 just fine.
Is 8 pin CPU the same as PCIe?
They are completely different.
Do I need 4 pin ATX?
This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it.
Can you use a CPU 8 pin for GPU?
Any combination of power pins can be used for a GPU, as long as the GPU doesn’t exceed what the supply can provide.
Do I need the additional 4 pin connector?
Usually you don’t need to connect the extra 4-pin (for a total of 12 pins), which means you only need the 4+4 pin (8 pin total ) connector on your Seasonic PSU. 8 pins are required, the extra 4 pins are optional.
Do I need both the 8 pin and 4 pin CPU power plug for my MSI b450 Pro Carbon?
From experience, it suffices to install the 8 pin connector on the left. The right 4-pin-connector is basically a redundancy that the CPU may draw upon under extreme load most likely only relevant when you do extreme overclocking.
Can I plug PCIe power into CPU?
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.
Can I connect CPU power to GPU?
Unfortunately, if you successfully connected a CPU power connector to the GPU and now the GPU doesn’t work, it may have been fried.
How many PCIe cables do I need for a 3090?
If you have two of NVIDIA RTX NVIDIA 3090 installed, then you will need 6 x 8 pin cables. The rest of the common expansion cards like a video capture card, network adapter, sound card, USB hub, etc do not require a PCIe cable.
What is the P4 connector used for?
1. The P4 connector is a 12V power supply cable used with motherboards that have an Intel Pentium 4 or later processor. Today, the connector is a standard power connector and is used with both Intel and AMD motherboards.
