So I am wondering if I am able to overclock with my ryzen 7 2700x, with an msi x470 gaming plus motherboard. I've only got the 8 pin connector plugged in cpu power 1, but not the 4 pin in cpu power 2. Does this make a difference?

MOBO: MSI x470 gaming plus
CPU: Ryzen 7 2700x
GPU: ASUS STRIX ROG GTX 1080 TI
PSU: Corsair RM750x
RAM: Corsair vengeance DDR4 3000 mhz 2x8gb
Cooler: Stock for now, but getting corsair h100i v2

The 4 pin is there for a reason.
It will supply extra power for overclocking and extra pcie slots.
Your motherboard manual should tell you under what conditions it is necessary.

If your psu has a second 4 pin cpu atx power lead, by all means, plug it in.

You can try things without the 4 pin plugged in, and it is likely to work ok.

I might just buy a molex to 4 pin cpu atx power adapter and plug it in.

And, if your case has 160mm available for an air cooler, I would buy a noctua NH-D15s.
It will be cheaper, quieter, more reliable, cool equally well, and will not leak.

Of the 1XXX and 2XXX series CPU's so far available none draw enough power to require use of that 4 pin.

Only AMD knows what's coming but listening to rumors: some are saying there will be more cores in the Zen2 product stack with maybe up to 16 cores/32 threads available. If so, that may very well be the only AM4 motherboard "future proofed" enough to allow safe operation of those CPU's.

When/if that day comes: buy an adapter 'Y' cable to split out one (at least) of the other 4 pins into two more. That won't help the fact that you're still using only 2, 4 pin connectors from the power supply but if something gives the meltdown won't be be on the motherboard at least. Of course, this also assumes you've a power supply that will deliver enough clean power in the first place.

UPDATED: Just noticed you've an RM750. That surely should provide enough power for a (theoretical) 16 core Ryzen on AM4. And isn't it modular? Did you lose the extra 8 pin CPU cable? If so you can buy one of those from Newegg: should be about 9 bucks.
