Your definately going to need a PSU with more than 300 Watts

If this is one of the smaller form factor cases (slimline) then you really struggle to get decent PSUs for them....

 

And why they build a decent spec PC like that and then just use integrated GPU is just madness....

Well then I guess I'm looking for a maybe 550watt that would fit, got any suggestions?
