You said the previous two units you tested shut down after you ran them at 450W. Did they both have the same switchers (FQAF11N90C)?

Also, 2SK2611 is rated for an ON resistance of 1.4 ohms max and 1.1 typical, and FQAF11N90C 1.1 ohms max and 0.91 ohms typical. That works out to a 27% difference, not a 32% difference.
