I'm not sure about that...
Compare, say, 10th level (to give the sorcerer maximum edge). He'd got say 4 x 5th level slots (assuming great Charisma) with which he can cast empowered fireballs. He only takes 5ft steps, since it is a full round action for him.
Each fireball does avg 35 *1.5 = 42.5 damage, Ref save DC 18 for half.
The psion can have the meditation feat that allows him to recover focus as a move action, so as long as he isn't unlucky he'll probably be able to use his metapsionic feat each round (assuming concentration = 13 ranks, +4 from Con would be +17 on a DC20 check).
So each round he casts an overchannelled maximised energy ball (fire), spending 12pp (his normal maximum of 10, +2 for the overchannel. A previous application of vigour could have given 50 temp hit points, so we won't worry about the damage from overchannelling).
Each fireball does 8d6+8, maximised = 56 damage, Ref save DC 20 for half.
At the end of those four rounds the sorcerer has used all his 5th level slots, the psion has used 48pp out of 113pp, less 10 for that vigour, means that the psion still has 55pp handy - so he could drop another four of those fireballs if he wants...
...assuming he doesn't have to worry about more encounters per day, as said above
