CPU 105W
GPU 166W (peak power from the 2060 review here at toms)

leaving 229 W for the drives, motherboard, and RAM and factory overclock.
400W should be plenty at stock speeds. the numbers above are at full throttle, most of the time the consumption will be under 100W.

what brand? what model unit do you have now? how old is it?
Well trust me its a poopy psu. And i dont even think its available outside turkey... never mind that psu. And btw you are saying 500+ watts is enough for my pc right?

a quality unit yes. ideally you would want the unit to run at 50% when the system is at full load so for your load @ around 300 W, 550 - 650W would be ideal for maximum efficiency.
as long as the unit can actually provide 500W. this is why I asked for the model and make, it may provide 300W on the 5V (junky units do this) and that is not gonna get your system up and running. you need at least 400W on the +12V rail

Do you have any personal recommendations for reasonable priced psus?

budget but good.
the seasonic S12II or the M12II that are 520W or 620W, the 450-500-550 units ending in 50 or 00 are junk and to be avoided.
the corsair CX series PSU with the grey label the green labeled units are junk and best avoided.

if the budget allows the corsair TX or RM series, the EVGA G2 or G3 series. the seasonic Focus series
