The Best PCI-E Riser Cables for Cryptocurrency Mining in 2022

7 Mins read

PCI-E or GPU risers are one of the most essential components for building a reliable and efficient cryptocurrency mining rig. Their main purpose is to solve the problem of installing multiple GPUs onto the same motherboard, even if the motherboard doesn’t feature enough PCI-E x16 slots, or spacing between them is too small to accommodate multiple double-slot or triple-slot GPUs.

PCI-E risers come in different variants and forms. Some of them feature full-sized PCIe 3.0 x16 slots, while some of them come with multiple USB 3.0 ports and PCIe 2.0 x1 slots. When it comes to cryptocurrency mining, risers with standard PCIe 2.0 x16 slots are the most popular ones.

Since PCI-E risers are used to connect multiple GPUs to your mining rig and thus increase overall mining performance, they also require a reliable power delivery in order to power up all those GPUs. High-quality PCI-E risers are designed to deliver 75 watts of power to your GPU via a 6-pin PCI-E power connector. Some of them can even deliver all this power via a 15-pin SATA connector, however, we don’t recommend using this method to power up your GPU, as SATA connectors are unreliable and may catch fire. Using a Molex connector is another option to power up your GPU connected to a PCI-E riser. Compared to the 6-pin PCI-E power connector, a single Molex connector can deliver up to 55 watts of power, so keep that in mind.

Another thing worth paying attention to when buying a PCI-E riser cable is whether the cable conforms to ATX specifications. Cheap PCI-E riser cables can usually deliver 54 watts of power, which is 21 watts less compared to what is required by ATX specifications. This can potentially overdraw SATA/Molex connector, and eventually damage your GPU. Also, if a PCI riser features a very loose connection to the motherboard, this can potentially cause a voltage drop, and thus set your GPU on fire by overheating of the wires and connections.

Great thing about PCI-E risers is they can also be connected to the motherboard via USB interface, and can be placed virtually anywhere. This allows you to build your own custom mining frame, and design your own cooling system to keep all of your GPUs healthy, and operating at full speed. Some high-end PCI-E risers come with LEDs that flash in case of an error, which is a handy feature in case of debugging your system.

Although there are many other ways which allow you to connect additional GPUs to your mining system (e.g. PCIe expansion cards, M.2 adapters, Thunderbolt controllers), using a PCI-E riser is the safest and the most reliable method to do that. Here are the best PCI-E riser cables you can buy right now.
