My simplistic math based on the numbers off Tim1’s Sankey flowchart shows that the combined collector efficiency is expected to be 80% and each collector is individually also shown at 80%.

Furthermore if efficiency of the combined power collection drops to below 61% then their is no longer a net surplus for the grid (the device would just manage to maintain self-cycling while throwing off lots of heat). If we assume 80% for the beam collector (the more mature technology) then the X-ray collection needs to be greater then 33% to still produce net power.

Naturally the net power output increases with higher efficiency, for each 1% increase in combined efficiency above the 61% floor the total net power output to grid increases by 263 kw or about 1/4 of a MW.

Any increase in Fusion output / input energy would of course change the break even points considerably.
