I look at it this way. I think EVGA was always going to charge $2499.99 but with the changing market conditions and glut of PSUs as everyone waits for the new standards they decided to bundle it with it to give more value to their always known MSRP and ship out some PSUs too.
Considering the 3090ti Hybrid was $2199.99, $2499.99 seems just about right for the pricing even before throwing in a PSU.
