USB3.0 PCI-E PCI Express 1X to 16X Riser Card Adapter with Big 4Pin and 6Pin Slot Connector

The riser seems to be high quality, it also comes with multiple options as far as power supply, etc. I don't like leaving negative reviews of products however I feel it is important that I do that with this product. I tried for almost a month to get it to work. (I bought 2 of them and neither would work)I tried 4 different video cards(3 brand new, one used) I also tried every port on the MB and every configuration of power cables possible. Nothing would work consistently. I also made sure my computer was up to date and also removed all video drivers and installed the latest ones. My computer would either freeze or go to a blue screen. I was monitoring the cards and when this happened while I was watching and could observe, it seemed like the card would lose connection. The fans on the video card would stop and the screens would flash right before it froze. I would have to restart the computer every time. I tried reaching out to the supplier with all of my specs, etc and wasn't able to receive any help with what was going on, other then it being suggested to return the product. I have returned it and received a refund.In the meantime, I have received some other risers, plugged them in and have not had any issues for 3 straight days. Same configuration, same power cable same slot, same video card. 100% stable with another riser!I am leaving 2 stars as I don't feel 1 star is warranted, as it would work sometimes, just never more then a day. I would think it might have been a defective product, but I had two of them and both of them did the exact thing.

Only been using it for a day, but it was plug and play, works great. Can finally move my 2nd GPU outside of my tower so it can mine quietly with proper airflow, the fans were driving me nuts.No instruction on if it needs one or two of the power connectors for the riser, seems to work either way, I've got 2 plugged in because I have the spare cables anyways. I suppose a more experienced miner should just know that anyways.

This was my first time purchasing a riser card for mining and I was very pleased how it turned out. I did some research and decided on this one due to the fact that it supports both 6pin pcie and 4pin molex power options.The package came well packaged and had an anti static bag. It came with a pcie riser card, 1x pcie to usb, usb 3.0 cable, and a sata to 6pin adaptor.It was easy to set up. Plug and play. I currently am using the 4pin molex connector, but I suggest using the 6pin pcie for power. Also, DO NOT use the included power adapter, plug the riser directly to your power supply!Performance. The riser performs almost identical vs plugging in directly to the motherboard. I would say within margin of error. I have pictures of benchmarks. Overall, very pleased with the product.

I am pleased with this purchase. Works as advertised. This is Ver 6 riser and supports my RX580 cards well. Came nicely packaged with good quality USB cable. Fits snuggly in PCI slot and the power cable is just right for the PSU that I have been using. Several of them using one outlet of my PSU.​

Works great in my mining rig. Bought a few extras but so far they have been running for 3 months and i have not had any issues

Worked great for the mining rig

This seems to work absolutely fine. I had an extra video card just lying around, but had no more room in the case. Now it is earning me an extra $1 a day.

I also received a dead riser as other reviewers have stated. Verified that another riser worked with the same configuration. Quality looked good otherwise.
