One month ago I bought brand new Gigabyte Radeon RX Vega 64 card and SilentiumPC Supremo FM2 Gold 750W PSU. Card worked perfect for the first three weeks. One week ago I started have freezes, black screens (this combined with max fan speed of card) or blue screens while gaming. I read somewhere else on this forum this is PSU problem and I need to connect card with two seperate 8-pin cables (which I did) and two different PSU rails, but I don't really know what it means. I also read it can be motherboard problem. Is it possible that my motherboard can not handle 750W?
My computer specification:
Motherboard: MSI B250M Mortar
CPU: Intel Core i5 7500
GPU: Gigabyte Radeon RX Vega 64
RAM: Corsair Corsair DDR4 2400MHz CL14
PSU: SilentiumPC Supremo FM2 Gold 750W
Thanks for your help.
