Using 60cm(2 feet) USB 3.0 cable as extender cable ,premium quality and super speedWith 3x FP solid capacitors, making graphics power supply more stable and secure.With SATA 15pin Male to 4pin power cable,more powerful,and reduce the burden of the motherboard.Compatible with 1x,4x,8x,16x PCI-E slot of the motherboardWith side clip to fasten other card
Risers are mainly for mining rigs(an may now they will be used in machine learning). The applicability domain is so small so I doubt a large manufacturer produces them, so I don't think you will find a well known brand.
The only advice I can give, is just to buy the ones with separate power cable and to avoid the ones with ribbon cable like this.
I would take a look in the picture and I would pick the one which appear to have the largest capacitors(the cylindrical electronics on the board, they are there to make the electrical current more stable).
I've built a couple of these sort of things and I've always used something like this for powering the HBA and then something like this to trick a normal power supply to turn on without a motherboard.
I just setup my rig (5 x RX480 8gb) with these: https://www.amazon.com/gp/product/B01CU1U2XG/
Just plug and play and they work without a hitch. Let me know if you have any questions.
The GPU has 5x PCI-1x and 1x PCI-16x slots. If you are using 6 cards (the maximum number supported by your motherboard), you will need 6 risers. You can actually fit a PCI-1x male end into a PCI-16x female slot in the motherboard, so 6 of these would do.
The cables may not be large enough to fit in whatever case you are using, but you should get the idea.
I would suggest grabbing 6 of those 8GB 480 cards. I think that is a better choice.
