The R4 is a fire hazard waiting to happen. They burn all PCI power connectors, probably a fault in PCB routing.
You should purchase a S9 and load it with braiinOS and underclock to 10TH / 850W isch
Much quiet than a R4 in this mode also run safer.
I havent had any problems with the two im currently running, they are solid pieces and wouldnt trade them for many other devices
They have been running nonstop since almost 2-2.5 years back
