i have a sapphire r9 280

it has 2 power cables on it and both of them have molex connectors

the packaging says i need to install the gfx card directly to the power supply

the power supply doesnt have molex connectors but it did come with a molex connector adapter

do i need to use the PCI cable that came with the power supply

or can i just use the molex adapter and plug that into the power cables on the graphics card?

this would put the connector labeled type 3 into the power supply
