I think the real question is why could the MW gate take the charge of a planet exploding but the Destiny gate couldnt take the live feed of a sun?

Assuming the MW gate did take the charge (I don't think it did) it would probably be because they're more advanced, also if memory serves it wasn't the Destiny gate that couldn't handle the charge, it was the ships conduits.

Gates can absorb enormous amounts of energy. Like KEK said, the conduits was the problem. It's practically always the problem of having enough energy, and when you have a sufficient energy source, you still need to get it into the gate.

Also, Rush made sure the power flow was limited.
