As title says, it's known issue for hackintosh. But it's more likely PSU or earthground issue, but if you wondering why it happens, know it's not critical.
You can change:
PSU
GPU
Case (yet, it can cause)
CPU Cooler (if AIO Water-cooling)
If none of them fixes your case, try earthgrounding on your home/house.
