I'm at the beginning my project, gathering together the components for the power supply from the bags in the kit. It seems that I can't find the electrolytic capacitator C3 as there is no electrolytic cap marked 680/35. However there is one marked 680 µf 50 V and it seems that it is not used in any other place. Can I use that as C3 or has there been a mistake and this component shouldn't be used but I should get a proper one somewhere?

Same thing here. Regarding its size and the pretty close value I deduced it was C3.

It would be a problem if the voltage rating is lower than 35V.
So i guess you're okay with that particular capacitor you have in hand.
I also don't see such a big capacitor footprint on the mainboard btw.

Same problem here, 50v instead of 35...hope it's not a problem

It just means the capicitor can be used in a circuit up to 50 volts. Since the circuit is less than 35 (the original value) you are well within the values this capacitor is rated for.

same here I panicked
