new graphics card has 12 pin pcie power connector

[wells2nn]

Looking at the specs of the 8gb RTX 3070 TI graphics card that I have just ordered it states that it has a 12 pin power connector on the card (but an 8pin to 12 pin adaptor comes in the box).

on the manufacturers website it states it needs 2 x PCIe 8-pin), what would happen if I only had one available ? or should there normally be spare ones coming from the power supply ? (I do have a 750w power supply fitted to the pc )

any comments / suggestions would be appreciated

You would need two separate pcie 8 pin cables from the PSU and both would need to be plugged into the gpu.

Hello, Thanks for the reply.

sorry, i am not near my pc at the moment. would the power supply not have come with spare 8 pin pcie cables already installed or will i probably need to get another cable ?

many thanks

You'd have to check, depends which model you stated you had. The welcome box would contain all spare cables so it may just need a secondary cable fitting.

ok thanks

The TXm 750 just comes with a single Pcie cable with a double 6+2 connector at the GPU end so would work, but ideally you'd want to get another Pcie cable with just a single 6+2 connector, or to make things look even better 2 of them so you don't have a spare 6+2 hanging around
