It is still ineffective; nbase-t port requires more power than dac or optical, on desktops it is just not dense, so it doesn't show up to the same extent. Switches with no poe can also have not enough juice to power rj45 transceivers in every port; it is quite possible to be able to juice up only every fourth port or so. Nbase-T is also higher latency than the others.
