Here is the thing guys, I wonder if my current PSU will handle the new GPU of AMD.

My Config:
> Intel i5 750 @stock (198W in full load)
> ATi Radeon HD 5870 @stock (354W in full load)
My PSU is a SevenTeam 550W

I will change the processor, I'll buy a i5 4670 that consumes 80W in full load. What means that I'll gain 204W, right?
If the TBP of the 290X is 404 informed by the PCOnline is correct, will my PSU handle the R9 290X? These calculus of mine has logic or not?

The i5 750 at max is 95W. And the HD 5870 at max is 50W. I have no idea where you got your numbers. The R9 290X isn't out yet so I cannot say what the requirements are. But if it is close to the R9 280X, I would say a quality 550W should be fine. Your SevenTeam 550W PSU appears to be a decent PSU so you're probably good.

I'm sorry I made a little confusion.

Those numbers are what the total system draws, measured at the wall. So you have to subtract the power lost in the power supply and the power consumed by other components.

An Intel i5-750 (Lynnfield) only draws 85 Watts @ full load with stock clocks when measured at the CPU's power VRM input.

The CPU would have burned out long before it was able to draw 198 Watts.

The i5-4670 would be drawing around 71 Watts @ full load with stock clocks.

A Reference Design Radeon HD 5870 1 GB draws up to 206 Watts when running Furmark stability testing and up to 158 Watts during gaming.

What is the Seventeam PSU model number?
