The PCI-E Riser for BitcoinLitecoin ETH Coin Ubit Mining Dedicated Graphics Card PCI-E Riser 1X to 16X Riser Card 164P / 60cm USB 3.0 Extension Cable & MOLEX to SATA Power Cable(6-PCS,6pin)

I would not recommend this riser. I ran the mining system for 4 days, and the system stopped working all of sudden. I thought it was psu problem in the beginning. However, it was one of risers that cause the problem. How did I find it? well, one of gpu got fried. I am so angry about this incident. I just lost $500.00 ,EVGA 1070 FTW, because of this cheap part. I have never left any comment in my life. If you want to avoid any hassle, STAY AWAY FROM THIS PRODUCT.

As most reviews have mentioned, the QA of these devices is low. I had a few bad and contacted the seller whom sent me replacements. None of the defective items have any visual signs of why they do not work.

Work great. Been running several months, no problems. Only issue I've had is that one of the foam pads fell off the bottom of one of the cards. No biggie at all.

Bad QC leads to burning video cards (in my case - fried Mother board PCIex16 where the display card goes). For sure not buying any risers from these guys! I thought I would pay a bit more for quality - but no! Disappointed in this product due to devastating results...

I found out after seeing smoke on my motherboard

Whats the point of having a foam on the bottom if it falls off after a day or two potentially hitting a fan.

no issues but newer models have come out

As described.

Spent two weeks in configuring BIOS, searching lot of google and other sites. None PICe riser worked. GPU works fine directly into the PCIE slot but same doesn't work with any of these risers. I didn't think for a second if all 6 PCI E risers are defective. When exhaust I bought a single PCIE riser from local shop to test and found it worked. Immediately I returned back these risers

Terrible risers. Do not use. One was burnt and actually destroyed my motherboard. The motherboard doesn't post anymore. Upon talking to UBit "support", they claim that the risers are installed wrong? I have 4 setups of 6 GPUs each and each one of them are working properly. Also, you can't install these wrong because they go in one way.

These risers are terrible. The ones i received are not the same as the ones pictured in the ad. Also a fee came with capacitors broken off, and others just didnt work . I purchased other risers and each one worked right out of the box. Dont cheap out on your risers.

Beware! I bought 4 boxes with 6 risers in each box. Three of those boxes came with faulty USB cables that don't work. The risers using the angular shaped USB connections did not work. I could swap the good cables between the connector boards from the other boxes and saw that all the pcb's worked. But, any time I tried to use the angular tipped USB cables in any combination of PCB's, video cards & motherboards, the rig wouldn't recognize the video cards. I've attached a picture showing the bad USB cables and the good ones.

Rated 1 star because so far NONE of the risers I've attempted to use thus far (2 out of 6) are working.My GPU does not power up with the risers. I've checked to make sure my GPU has power (it's plugged directly into the PSU) and I've even tried connecting the riser directly to the PSU instead of using the MOLEX/SATA adapter to connect it to the PSU.
