1x8gb 2400mhz or 2x4gb 2400mhz?

Which can do more power?

Typically dual channel performs better but there are some games that actually perform better with a single stick but tbh the differences are still pretty minimal (range from 2-10 FPS), If your motherboard has 4 slots then I'd go with a 2x4gb kit, if only two slots then 1x8gb.

Note that if you add any kits to an existing kit there is a small chance that it won't be compatible even if its the same exact model.

I also want to add in that I was questioning this recently and the results are mixed, at least for gaming.

2x4gb

Assuming your MB is 64-bit and supports dual channel, 2x4gb will perform better if they are matched (paired) by the manufacturer. But 2x8gb is even better yet IMHO.

2 x 4gb will operate in dual channel mode which is faster than 1 x 8gb which must operate in single channel mode.

Not so important if you have a discrete graphics card, but very important if you use integrated graphics.

Today's games are starting to use more memory and works better with the combo :
At least 4 CPU cores and 8 Thread.
A good gpu that works well in Dx12 and older games with at least 6gb gpu memory ( Nvidia 1060 6gb or better / And Rx 580 8 GB or better )
And For System memory I'd advise fast memory at 2600 or faster for Amd Ryzen and 2x8Gb to start with.
Hard drive should be a good SSD for system and most played games, normal hd for other stuff.

So if you can't buy right now 2x8 GB I'd personally go for one 8gb and upgrade later, the performance hit is not huge but rather low ( 6 to 10 FPS at low Res ).

What are your other components? Do you plan a future memory upgrade? How many memory slots does your motherboard have? What do you use your configuration for?
