vostro 3910 psu problem

the dell site shows that the dell vostro can came with a gtx 1660 super and 300w psu but heres the thing i have seen that the 300w psu that comes with dell vestro has 8+4+4 pins if the motherboard takes a 8 pin then how does the gtx 1660 super gets power if i recall the gtx 1660 super needs a 8 pin does dell use a special oem gtx 1660 super ?or the psu comes with 8 pins for the gpu and im wrong?
