Hi All,

Does anybody have a clear idea of this error

BIOS screen saying "please install the psu's 4-pin power cables to the 4-pin power connector on your motherboard".

I have 1 psu - 1050W and have power to both MO molex.   One GPU ok in either x1 or 16 sockets but when i add another gpu i get this above error in the bios so stopping me from booting.

have ribbon powered risers.

Set to gen2 and default to onboard graphic card.

Any Suggestions?

cheers

Nick
