It would just put extra thermal load on the GPU.

Passing power through doesn't have to put noticeable load on the GPU. The main problem I see there is getting even more power to the GPU - Nvidia's top cards are already at the melting point for their power connector.

    I specifically said thermal load. Power delivery always causes heat dissipation due to I^2^R losses.

    That's what I meant. Compared to the power the GPU is actually using, transmission losses for a pass-through should be negligible. If you have a good way to get it to the card in the first place.
