Best PCI-E Risers and Extension Cables To Buy in 2021

Even though PCIe riser cables have been around for quite a time now, these cables have gained immense importance recently. A few years back, the hardware was not much demanding or space consuming. As a result, no one really cared about cable management or the aesthetics of a PC build.

Nowadays, the trend of spatial orientation is growing, and PCIe riser cables provide a perfect means to address this trend. The PCIe riser cable allows you to extend the PCIe port of your motherboard, so you can place your GPU at a preferred location inside your case. This makes it easier to build compact cases or even use a multi-GPU system.

In this article, we will review some of the best PCIe riser cables available in the market so you can make the most acceptable choice possible.

Why Use a Riser Cable?

A riser cable has many advantages, with the following two being the major ones:

  • Aesthetic reasons: The riser cable can allow you to flaunt your GPU in various orientations
  • Space Constraints: The riser cables permit much better placement of Single or Multi CPU configurations. This also provides better wire management and better air ventilation to keep things cool.

Manufacturing companies are focusing more on bringing out GPUs, which keep growing more powerful. Still, size also increases with power and better features. Although there are smaller GPUs available, they aren’t as powerful as the ones which are larger. GPUs are very bulky and occupy a lot of space.

Suppose you consider professional gamers or content creators. In that case, they will always choose the powerful yet more extensive GPU over a compact one with fewer features. Moreover, if upgrading an older system might also be a pain in the back.

The PCIe riser cables provide you with the ultimate ability to relocate your GPU to different locations within your case. This way, you can make room for other components which can be placed at specific preferable positions in your case.

The Riser Cable can come in handy, primarily if you use a multi-GPU system. This way, you can enhance your performance to the maximum.

What Is the Difference Between Different PCIe Standards?

PCIe slots come in varieties differing in types, sizes, electric bandwidths, and other features. The GPUs require the longest PCIe slots, which are the x16 PCIe slots due to the GPUs high bandwidth. The different PCIe bandwidths are the PCIe 1.0, PCIe 2.0, PCIe 3.0, and PCIe 4.0.

A PCIe 2.0 x16 will only be half as fast as a PCIe 3.0 x16. Moreover, a PCIe 4.0 will be much faster (almost double) for both of them.

So, if you’re shopping for a PCIe Riser cable, it is important you know a couple of things. First of all, you must be aware of the required electrical bandwidth of your GPU. For example, some GPUs run on x16 PCIe 3.0. Secondly, you must also know the required mechanical slot type of your GPU.

What Are PCIe Extension Cables?

A PCIe Extension cable is just another variety of PCIe riser cables. In place of a bracket, these cables are just plain male to female PCIe cables. These are so designed to provide you flexibility in where you place your GPUs. They are ideal, especially for gamers and content creators, as the extension cables maximize the cooling performance of your system.

The advantages are more clearly seen in a multi-GPU setup for GPU rendering. If you space the GPUs further apart, you’ll be able to achieve higher clocks on your GPUs along with longer boosts while keeping the temperatures low. This will result in a shorter render time.

When hunting for an extension cable, you must remember that length does not specify how good an extension cable is. Even though it provides you with better options to place your GPU, it can make cable management a hectic job. Other than that, longer cables are prone to decrease the signal quality being transferred. Therefore, it is recommended to get a cable as short as possible.

Will a PCIe Riser Cable Affect My Performance?

As long as you are using high-quality riser cables and you know how to handle them perfectly well, you won’t face any negative impacts on your performance.

Some users daisy-chain their cables and might face power supply issues. But this depends on how well your cables are built. Although this might not be a big issue for gaming and other tasks such as content creating, it’s still essential to check the daisy-chaining ratings by the manufacturer. This is especially important for crypto miners.

Some users also come across issues due to the locking mechanism. You must make sure the lock keeps the plug secured in its place.

If you further want to make the performance of the Riser cable better, make sure a decent magnetic shield is present. This will help eliminate any interference and provide you with the best performance.

What Should I Look for in a PCIe Riser?

There are a few points you should keep in mind before you shop for a Riser cable. This will help you choose the perfect product to gain maximum performance.

Cable risers are supposed to extent how far PCIe slots of your motherboard reach. That way, PCIe components can be placed and oriented in different ways. While looking for the best PCIe riser cable, you should lay most focus on optimal performance in bandwidth along with compatibility. You must be aware of your PC case dimensions, the bandwidth compatibility, and whether you’ll require holding brackets.

 You should know that there are two types of riser cables: The powered and the unpowered.

Powered Riser Cables

These riser cables use a secondary power supply, which is an internal USB connection most of the time. There are usually used for crypto mining and connect to an x1 or x4 PCIe port while housing an adapter for your GPU.

You should know that even though the GPU-facing slot on the powered riser cable has an x16 interface, the motherboard’s connector has only x4, meaning it cannot transfer speeds higher than x4 bandwidths. Of course, this will only suit you if you do not require bandwidths higher than x4, which is why it suits mining.

While buying a powered riser, it is beneficial to buy one having a USB 3.0 port. This makes it easier to connect to the motherboard.

Buying a powered riser with more capacitors is also beneficial as you’ll get a more stable power supply. Your riser cable should have at least three capacitors for optimum performance.

Unpowered Riser Cables

The unpowered riser cable does not extract power from an external source but rather draw power from the motherboard. These directly use the motherboard’s x16 PCIe port for their power supply and allow faster bandwidths.

Wrapping It Up

Well, this is the end of our in-depth review of some of the best PCIe risers and extension cables. Regardless of your bandwidth and needs for interfaces, the products on our list will suit you perfectly.

The best product on our list is definitely the Thermaltake TT Premium Extender Riser Cable which is absolutely flawless. You should know manufacturers provide varying sizes of the products, so it’s better you go through that first.

We discussed the best Riser cables available in the market for you to choose from. But, of course, the choice you make depends on your requirements, and obviously your budget. Hopefully, after going through this article, you’ll easily make the right choice and buy the Riser cable which suits you best.
