I think you're getting this turned around - at least this is how I am interpreting this:If the GPU's thickness specification includes the backplate, then it can be up to 45mm.If the GPU's thickness specification does not include the backplate (but the card most likely still has one!), then it can't be thicker than 40mm, as there will inevitably be "additional" thickness behind the PCB from the backplate that isn't accounted for in the spec.In both cases, actual, physical thickness of the GPU can be the same - up to 45mm total - the difference is how thickness is measured and specified by the GPU maker.I might be the one who has everything turned around in my head, but at least this is how I understand what has been said.
