Can you extend PCIe power cables?

The Cable Matters 6-Pin PCIe Power Extension Cable provides a convenient solution for extending the connection from a power supply with a 6-Pin PCIe cable to a video graphics card. Extend the length of your 6-pin PCIe power supply cable for better cable management with this sleek-looking, sleeved cable.

Is there a PCIe Extender?

PCI-E PCI Express 16X Riser Card Extender Flex Flexible Extension Cable for 1U 2U Small Case.

How much power can PCIe riser provide?

PCIe and SATA Power Details The PCIe spec specifies a max of 3 Amps of 3.3V power and 5.5 Amps of 12V power. That translates to 66 Watts of 12V power and 9.9 Watts of 3.3V power.

Is PCIe powered?

PCIe cables connect directly from the Power Supply Unit to the installed PCIe Expansion Card; Graphics Card. A typical PCIe x16 slot on which you install the graphics card supplies 75 watts of power.

Are GPU extensions safe?

If still concerned then install the extension in some test environment so you are not risking your build and GPU’s. Run for at least 24 hours with some load – that should be enough to verify that the extensions are okay for use. Unfortunately, there is still no guarantee against failure.

What is a PCIe power connector?

The PCI Express x16 connector is used primarily for high speed data transfer between the graphics card and a motherboard. However, the connector has a handful of pins that allow it to provide up to 75 watts of power through motherboard.

Does PCIe connect to GPU?

PCI Express x16 Connector Motherboards come with the aforementioned PCI Express x16 slot that can provide a maximum of 75 watts of power. Some feature multiple PCI Express x16 slots in order to connect more GPUs but, as previously mentioned, this increases the power requirement.

Do PCIe risers need power?

The PCIe slot needs both 12V power and 3.3V power. So, in both designs we’ll need to generate 3.3V power from somewhere. The power connectors that drive GPU riser cards come in 3 flavors: 6 Pin PCIe power plugs, 4-pin Molex Connectors and SATA power.

Do PCIe extensions affect performance?

Retired Moderator. No extensions are perfectly fine. Also virtually no difference in lane SPEED.

Do PCIe risers need 5V?

The PCIe slot needs both 12V power and 3.3V power.

Do I need to power the risers?

Yes you need to power the riser, the GPU still draws power from the PCI-E slot. Yes you can power the riser via molex, but not more than two risers per string of Molex cables. A molex cable typically has 4 connections, you can only connect 2 risers to the 4 available per cable.
