i have this power supply and i wish to upgrade the gpu from a gtx 760 to a 1060 6gb , the issue is that the 1060 uses 1 8 pin connector and my 760 uses 2 6 pin connectors can i use a Athena Power PCI Express 6-pin to 2 PCI Express 2.0 8-pin (6+2-pin) Adapter to complete the 8 pin requirement? . According to the manufacturer the card needs 400w psu and mine is 500w can this be viable to do or should i get a new psu (don't want to not enough money unless its absolutely necessary) thanks !
