i reckon when the golden throne finally breaks the emperor dies, as in whatever lifeforce remains in his corpse is extinguished and his mind (which is still connected to his withered flesh) also dies.

this would be an exceptionally painful and woeful death. because the emperor believes his warp presence is the only thing that's helping the human race to survive then he knows his real death will result in the death of our species. the guilt and grief he then feels for letting us down results in galaxy wide warp storms (as he is winking out of existence), decimating the other species of the galaxy because if we can't have it then no-one should (along with his inability to understand general emotion he is also toweringly arrogant, and a little petty).

so the imperium disappears, the eldar are enjoying their 'sexfest ' (nice one legion :) ) and the rest of sentience are much reduced allowing the tyranids to have a gentle picnic on the remains :)
