Just ordered two on amazon, hopefuly thats gonna solve the issue...
Did it solved the problem? I have almost the same issue...
And if anyone know, how to connect them when using 2 PSUs.
Is it better to connect all PowerRisers to the 1st PSU (which powers the MB) or they should be connected to the same PSU where GPU Power PCI-e connect to....
PR = Power Riser
PR1 to PSU1, GPU1 to PSU1,
PR2 to PSU1, GPU2 to PSU1,
PR3 to PSU2, GPU3 to PSU2,
PR4 to PSU2, GPU4 to PSU2...
Thanks in advance!
