Will there be bottlenecks? If so, how much?

Solution
They will run just fine on a CX500, unless you go bananas with the overclocking. And the FX4100 won't exactly bottleneck the 7970. It's fast enough to keep up with the 7970, but there will be maybe a 10% FPS difference between that and a 4770K in most games. Mind you, that's MOST games, not all. There are a few of them out there that really demands a beast CPU. But I don't think those games are too common.

would having a cpu cooler+ extra fans affect my power consumption that would surpass the cx500's watt?

That's a tough call, 500W would be cutting it close if you throw in extra stuff. The CX600 shouldn't be that much more expensive, better safe than sorry. And maybe look into the CX600M with semi-modular cables, it'll make cable management so much easier.
 
just pay the extra for a 600w. cx series arent that great. It it were a higher end corsair with more power available on the 12v, i would say yeah 500w is fine. You will see a bottleneck depending on game, eg bf4/3 multiplayer with 64 player maps will see the cpu as a serious bottleneck. But if you spend a little extra on a psu now, you can always upgrade to a 6 or 8 core piledriver cpu in the future.
