  • The illustration shows one GPU adapter installed on each riser card. If there are two GPU adapters installed, the GPU power cable is a Y cable.

  • If your GPU adapter TDP is equal to or lower than 75 watts, the adapter can be powered directly by the riser slot. Power cable connection is no needed.

If you need to install an M.2 backplane on the GPU air baffle, refer to below illustration for cable routing on the air baffle. Route the GPU power cable from riser 2 beneath the M.2 backplane holder to the GPU power connector on the GPU adapter.
