Can you extend PCIe cable?
Table of Contents
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.
Do PCIe extension cables affect performance?

Retired Moderator. No extensions are perfectly fine. Also virtually no difference in lane SPEED.
How long can a PCIe extension cable be?
The maximum length for PCIe cable (all lane sizes) generation wise are as follows: PCIe Gen 1: 15 inches. PCIe Gen 2: 12 inches. PCIe Gen 3: 8 inches.
Can I use a PCIe 3.0 riser cable in a 4.0 slot?
In theory he is right, IF (and thats a big IF) the riser was made well enough then it could work in PCIe 4.0, in fact AMD mentions this themselves, but they also say that while it could work, if its not certified at PCIe 4.0 it could cause stability issues, they highly recommend to limit the slot to 3.0.

Are GPU extension cables 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.
Where do PCIe cables go?
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. This, is not nearly sufficient for many mid to high-end graphics cards.
Does GPU extension cable affect performance?
Most likely, not. By introducing more space between two components you require the electrons to travel further. This increases latency.
Are PCIe risers universal?
Any PCI Express will do. You can use riser with any interface version: x1, x2, x4, x8, x16. The riser will always work on 1x speed, which doesn’t affect the mining performance at all.
How long are PCIe risers?
The Thermaltake AC-045-CN1OTN-C1 is a PCI-E x16 3.0 Riser Cable that will enable the full Bandwidth for your PCIe-3.0 GPUs. The riser cable measures 30cm in length, making it a great choice for long runs.
What is the difference between PCIe 3.0 and 4.0 riser cables?
PCIe 3.0? PCIe 4.0 is twice as fast as PCIe 3.0. PCIe 4.0 has a 16 GT/s data rate, compared to its predecessor’s 8 GT/s. In addition, each PCIe 4.0 lane configuration supports double the bandwidth of PCIe 3.0, maxing out at 32 GB/s in a 16-lane slot, or 64 GB/s with bidirectional travel considered.
Do PCIe 4.0 riser cables exist?
While providing double the bandwidth of PCIe 3.0, the Gen 4.0 riser cable remains backward compatible with a maximum transfer speed, offers great performance, and shows off the GPU at a great new angle.
Are cheap extension cables safe?
Yes, be wary of cheap extension leads – they are almost always cheap for a reason. It’s not worth the risk. The best way to protect you and your family from potentially dangerous goods is to buy from a reputable retailer.
How long is the PCI-E 16x riser card?
