This review is for the 4 to 1 expansion board. This thing works amazing. I only needed it for three video cards so I can't say if all 4 worked but it works well. I am using an Asus Z-270A motherboard and running Ubuntu 16.04. This rig now is running 10x EVGA 1060 SSC video cards with the memory transfer overclocked by 1000+. Getting between 22-23 MHs with all cards regardless through PCIE or motherboard or the 4 to 1 expansion board. I will definitely buy one for my other 2 rigs and expnd them here shortly.

This works, here Is what it did for me. I have three video cards. two gtx 1070's and one gtx 560 ti without this card my motherboard would only see the 1070's in the primary slot. If i put them on a riser in any other slot they were not detected. they would be detected if the riser was in the primary slot. the 560 would get detected no matter where I put it so at max I could have one 1070 and the 650 going. I plugged this in to a random slot and connected my 2nd 1070 and the 560 card to it. when I got in to windows I could see the two 1070's but not the 560. shutdown connected both 1070's to this put the 560 in the primary slot started up everything was detected. I used the same slot on the card that the 560 was not detected in for one of the 1070's so its not a port problem its just this riser does not see the 560. So moral of the story it may not work for older video cards but it did make it so I could see all my 1070's running two cards at exactly the same speed as when they were in the primary slot. I have two more 1070's on the way but probably wont update this review unless I have trouble.

For all the miners out there: THIS WORKS.

Please note: do not put this in the primary pcie slot or system will not boot! Have 1 card in primary slot. Will work in any other slot.

The risen serve the purpose of extending the PCIe x1 ports to four PCIe x16 ports, although obviously we are only sharing one line for all.
It does not work to perform CrossFire and much less an SLI, since everything you connect will be connected to the same port and using the same PCIe line to the processor, so you will not have enough bandwidth to play or perform any demanding application.
The purpose of these riser is exclusively (at least 85%) is mining, I bought it to prove that such a Dell R200 server accepted four AMD graphics cards and mine some cryptocurrency, I worked perfectly and according to the purpose of these components.

Well built parts, worked for me for my needs, all things considered. It actually comes with a splitter and 4 risers. I used the splitter for two cards in a computer and used one of the risers in another card. It really depends on your mobo if it will support more cards though. Mine only supported 2, but that is not this product's fault. I used the other risers in another computer, so it worked out well. Seemed to work in Windows 7 and Windows 10 for me.

As other users have stated, I was unable to get the 4 Port PCI card to work in the Asus z270e board, but since this kit also came with the PCI connectors, I was at least able to use this as a standard riser kit. I tested this board in several slots, but none were recognized by Win 10.
I assume it's an issue with the Asus board however.

All four risers worked flawlessly. The first splitter board burned up after 2 days of use with a very noticeable "something electronic fried" smell that filled my office. No smoke sparks or flames that I noticed. I contacted the seller and they quickly shipped me another that has worked fine, but I'm dropping a star because that does make me somewhat paranoid about it. It didn't hurt my system any.

Works well on a biostar racing GT intel 1151 motherboard. I didn't realize that board had some PCI slots on it, this solved the PCI-E shortage.
Comes with complete single PCI-E to USB riser cards to plug into mother board if the quad card doesn't work, though mine seems to be fine.
Pros: all of the above, the riser cards are nice.
Cons: None so far except that windows 10 took a reset with power on in order to notice the first gpu on this thing. Before that it seemed to not be working at all. Power cycles and reboots didn't do it, but I hit the reset with windows running once and it fixed everything, boots fine now. Quirky behavior that might be unique to my setup
