Best power option for GPU on MP3.1

crwdns2934249:0crwdne2934249:0:

Hi guys,

I want swap my old HD4xxx (2x6pin power from board) for RX560/570/580 (1x8pin). But I am not sure what will be best power option ? All RX 5xx have max 225W what should be OK for board so no need PSU modification.

Power over PCIe is 75W + 1x6pin 150W = 225W - it's on the edge. And Also most of the GPU have 8pin instead 6pin so I need different cable. But instead 6pin->8pin I like to use 2x6pin -> 8pin.

Will this solution (2x6pin to 8pin) take power from both 6pin connectors from board + pcie ? So I don't have to worry about any crashing etc?

Any ideas welcome, but I'd like to avoid modifying the PSU :)
