PCIE standards for GPUs are fast evolving, and vertical display of video cards is becoming more and more popular. In order to do this, you need a riser cable. Buyers beware. Most PCIE risers are from knockoff companies that claim the speeds will reach their potential maximums. This is far from the truth. In this space, both price and brand deliver and guarantee what you're looking for. Trust Lian Li, who has been in computing for ages with high end cases, RGB cables and now riser cables at true PCIE 5 x16 speeds. Take a look at the pictures comparing a knock-off PCIE 5 Riser (white) with the Lian Li PCI-520X PCIE 5 Riser (black). The cabling on the left side of the ribbon tells you all you need to know. How do you know your cable is PCIE 5? EZ PZ Follow these instructions: 1) In your bios, make sure your PCIE Link is set to PCIE GEN 5 for your GPU slot and not AUTO 2) In your bios, make sure your multiplier is set to x16 and not AUTO That's it! If you leave it at Auto, if you have a knockoff PCIE 4 or PCIE 3 riser being advertised at PCIE 5, it will work because the mobo will automatically set the speed to work. That's why it's automatic. That's why people buy the knockoffs because the system posts and you're none the wiser. If you set PCIE GEN 5 at x16, a knockoff cable will NOT allow your system to post past the bios startup screen. Your Windows 11 login will never show up and you will only have a blacked out monitor that doesn't receive a signal because the cable cannot transmit at these speeds. There are a few other ways to verify, but this is the easiest. CPU-Z doesn't always show 32 GT/s for current link speed, which is the max for PCIE 5x16. This does not necessarily mean you're not at PCIE 5 x 16, it just means it's not transmitting at that speed (e.g. false negative). The other way you can verify is to slot your GPU directly into your motherboard, benchmark, and do the same with the riser and vertical mounting. You literally should get the same score within a few points on 3D-Mark and any other benchmark for GPU. If you see a huge discrepancy the riser is a scam. Perfect compatibility with my new MSI RTX 5070 Ti. Fits perfectly into the slots securely, and the 90 degree connector to the GPU is amazing. Makes routing the cable much easier. The quality of Lian Li is amazing. Highly recommended for $70 dollars. Read more

Straight up did not work. Was able to confirm by taking a cable from another system this this riser was the problem. Took HOURS to barrow down the problem, I dont feel a refund even makes it right. Read more

Works great, and PCIE 5.0. Read more

Good Quality! Works as described! Read more

It is not as advertised or as shown in the box... if you check the cable it shows pcie 4 unfortunately. And i had issues with it (the blue screen of death). Read more
