Explain: 
Regarding the output cable you enquiry is the model of other suppliers, we don't know the exact specification of the cable, so we cannot offer the price of the cable. Because the cable is the accessories of GPU, we can make the quotation and supply these cable, after we get the specification and length of the cable.
