That depends on the number of PCI-lanes (
not slots) of you Mobo and firmware compatibility,
if it's a low-end mobo with old procie (
typical 2-slot MoBo), it wont work.
You'll never know unless you try, or...
You should provide your Rig's specs (MoBo model and processor) to know if anyone who have the same model have tried a '1-4 riser' that worked.A random guy who said "
yes" but with different specs won't be reliable.
1. My mobo model is F2A88XM-D3H. Below is the link.

Right now this motherboard is handling GTX 1060 and GTX 1070 cards. I wanted to use risers to increase the number of cards and also I wanted to keep them ventilated. Due to space constraint this 1 to 4 PCIE riser seems best fit for me since it just uses one USB Cable to connect to 4 GPUs.
