Do 1 into 3 PCIe Risers work?

[Storx]

I was reading up on builds different people posted, one build the guy posted i noticed had 8 GPU's...but when i looked up his motherboard he listed that he used it only had 1 x16 slot and 5 x1 slots.. so it boggled me how he had 8 cards running and when i looked closer i seen a riser with 3 cables coming from it.. googled it and found these risers... do they really work? any issues using them?

yeah it work some motherboard will support that, but why you want to spending more money on something like that when they are releasing thr h110 pro btc, with 14 pcie 1 slot? it will cost you much less

Yes they do work but there are also many motherboards that have been found that do not support this.
It's actually a shot in the dark at times but if it does work then enjoy!
