Is anyone using RX 480s with powered risers? My system runs for about 8 hours then reboots. Plus the control center is the newer one and doesn't show temps.
I have the molex powered risers. That is connected to the motherboard PCIE slots as well. That is safer.
I ordered some they should be here today or Tues. Waiting for them before I add the 4th card.
Do not use the USB powered risers as they do not connect to the motherboard, all the 75W is from the SATA power cable.
I am using the H81 Pro BTC ASrock motherboard.
Molex powered and also PCI-USB3 riser powered from SATA cable from PSU (EVGA-G2-1300w)
My test system is running solid at 24.xxMHs per GPU for more than 20 hours!
Does the USB powered risers also connects to the PCIE power +12V slots on MB? If it does, there is no problem.
