LINKUP - AVA5 PCIE 5.0 Riser Cable | RTX5090 RX9070 GPU Ready | x16 128GB/s Speed | Compatible with PCIe 4.0 | Designed for ITX | Single Reverse Straight, Black 23cm (Total Length 27.5cm)

tldr: get the 20cm cable for a Corsair Frame 4000D case. Supports both gen 4 and gen 5 pcie.This 15 cm cable just barely fits on a Frame 4000D. It’s fully stretched with it being installed on the holes meant for the 4 slot cards. I would definitely recommend going with their 20 cm cable instead, as I’ll probably be returning this one for a 20 cm myself.Now, Corsair includes 2 standoffs that must be installed first. The screws provided do not fit through the holes on the riser cable easily, you kind of have to force them in a bit. Unfortunately I can’t test gen 5 capabilities yet; I’ll update when I get my new card. 4080 Super is currently doing great under full load though.EDIT: got my 5090. GPUz is reading at the full PCIe x16 Gen 5 interface. Holds it well in stress tests. I would like to clarify the standoffs; you can in fact screw the riser cable directly onto the Frame 4000d. However, this works ONLY if you buy their 20cm cable. The 15cm would definitely be too short. I waited to get my 5090 to tell anyone buying this cable with this case in mind, the connector bends if you keep the 15cm on the standoffs. Hopefully the picture helps.

I built a new PC in a Dan A4-H2O case and was experiencing intermittent crashes and restarts. I thought it might be due to the riser cable included with the case. I ordered this cable as a replacement and the crashes and restarts stopped happening and have not happened since (it has been a month or so). This cable is rather expensive, and maybe I could have gotten a replacement cable from Lian Li, but I wanted something delivered quickly. This cable is also a few centimeters shorter than the original cable which had too much slack, so it is a more efficient use of limited space in the small case.

I have been vertically mounting GPU's for awhile, I upgraded to a 3090 RTX card when available and had to switch back to horizontal mounting. Why? Because the vertical mounting kit I was previously using had a riser cable that simply did not work with Nvidia 3000 series GPU's.Ordered this cable and it works now, back to vertical mounting! I ordered the 20cm, my case is a Lian Li 011 XL. To be honest it is a tiny bit long, I think I could have gotten by with the 15cm cable, but it would have been a close fit.With newer cards like the 3080 etc I would even suggest vertical mounting is functionally a better choice too in a large case. I saw the temps on my RAM and various other system points go down anywhere from 2-5 celcius after switching back to vertical. This is because the horizontal mount blocked the intake from the fans at the bottom of my case, and placed the GPU much much closer to the other components on the mobo. Meanwhile the GPU itself under full load basically hit the same max temp regardless of mounting orientation.UPDATED NOTES: I am seeing the same questions asked constantly and relentlessly, which cable should I buy, what length, etc etc etc. The answers are almost always the same, so read on if you want to know which one you should buy or if you even should buy one.1: Right angle or Straight?Answer - Is your case an ITX case? If not, the answer is Right Angle, the end. Doesn't matter if it is full tower, mid tower, or what vertical mounting adapter you are using. Unless your case is an ITX case you want the Right Angle version. If you ARE using an ITX or Mini ITX case you want the Straight angle.2: Will it work with my motherboard XYZ into infinity? Answer - Is the primary PCI Express slot of your motherboard PCI-E 3.0 or higher compliant? If the answer is yes, then yes, this cable will work with your motherboard.3: Which length should I buy?Answer 1 - If your case is a ATX Mid Tower or Full Tower case you are almost guaranteed to be fine with the 20cm length. If anything it will probably be slightly long. You may even be okay with the 15 cm length, for example with the Phanteks P500A case (which I have used in computer builds) the 15cm version will be long enough though it will be a little snug. Any less than 15 I probably wouldn't risk it unless you are vertically mounting the GPU in the highest possible position. For reference both of the riser cables included with the old Phanteks vertical mount kit and the new EKWB kits are around 18cm.Answer 2 - But what if I have an ITX case? Then you probably already had a riser cable included with the case. You need to remove that riser cable, measure it, and order accordingly. I am sorry but doing anything else is just rolling the dice unless you have specific manufacturer documentation stating the required length.4: The question you should ask but probably don't... Do I even need this cable?Answer - That depends. Do you need to replace your existing riser cable for some reason? Maybe it went bad or there was a recall on it? If so than this cable is a good choice. Alternatively, are you in my situation where you upgraded to a newer card like a RXT 3080 or Ryzen 6800XT and your new GPU wouldn't work with your old riser cable? Then yes, this cable is a great buy.However if you are buying this cable for no reason other than "PCI-E 4.0!!!!!!" You absolutely do not need, and should not buy this cable. You are extremely unlikely to get true PCI-E 4.0 speed over a riser cable, even this one. Also extensive tests have been done by many trusted tech groups and reviewers that have proven forced PCI-E 4.0 has extremely minimal performance gain over 3.0. Most often less than 5% gain, sometimes as little as 1%. A theoretical maybe gain of a couple percent (which translates generally to only 1-3 frames) is not worth 70 dollars.The thing that makes this cable good is that it has been factory tested with all modern graphics cards and is guaranteed to work with them. No other riser cable on the market that I know of, and certainly no included riser cable that comes with a kit, can claim the same. The PCI-E 4.0 compatibility is a cool marketing spiel, but it is not a reason to buy this riser cable. 4.0 compliance does not mean 4.0 speeds.

Update: So LINKUP reached out and provided me a refund. They also updated their item description that shows the cable will work with the case with a mod only. It is more a hit on Phanteks to use a non-standard size bracket at the end of their pcie cable. The cable itself funcions as advertised. Thanks LINKUP!Original: So the cable technically functions as PCIE 5.0. The problem I have is that the width of the mounting bracket at the end of the cable (with the 2 screw holes that connects to the case) does not, I repeat DOES NOT fit a Phanteks Evolv Shift XT case. It clearly states in the 2nd photo in the description that the 19cm double reverse v2 and v3 are compatible. I no longer have the box that cable came in because I thought it would be impossible for it to not fit... sigh. I will try to do a return but I doubt they will support it. I will update this depending on the outcome.

This exact one, "Double Reverse, Black 20cm (Total Length 22cm)", is the one you want for replacing the riser in the Lian Li A4-H2O case.I was able to fasten screws in the top most outer holes on both sides into the case mount.I did have to cut a piece of the top plastic off (see picture) in order for the riser to not come directly in contact with my AIO fans.

While testing three 25 CM cables with three 5090s (plus a 5090 connected directly) with a VLLM workflow, I consistently crashed when I hit ~16 GB VRAM usage with a strange GPU exception "NVRM: Xid (PCI:0000:XX:00): 13, Graphics SM Warp Exception on (GPC 0, TPC 0, SM 0): Out Of Range Address". I restarted and looked through BMC logs, nothing obvious, still hitting that same exception when compiling. Once I connected the 5090s to the PCIe board directly, however, on next boot my VLLM workflow compiled without a hitch. Maybe it is my fault for using this length but I am not sure why you would sell them this long while still claiming PCIe 5.0 support if you cannot deliver a stable PCIe 5.0 experience, especially at this price point.
