Question about my pc components god I'm not good at this

[Bugplayer]

Hey there!
I'm totally close to 0 knowledge when it comes to pc, feel free to roll your eyes as much as you want.

So I have this graphic card sitting here. It's the msi R7770-2PMD1GD5/OC.
And I want to take out the one from my computer which is totally garbage, and put this one instead.

Unfortunately. my case is very small, so it doesn't quite fit because I have these 2 cables plugged (unplugged in the picture) in the first 2 of these 4 sockets of this image here.

So my question is. Can I move these 2 cables a couple sockets down to make a bit of room?
Also, while I'm at it. How can I know if my power supply can support this new card?

Thanks a bunch for your help.

Looks like SATA cables so, no problems at all.

About the PSU, depends the wattage of it. If you can take a photo, i will help.

Sure thing, and thank you for the reply.
Here's the image.

I assume that Max power output is what we're looking for. If that's the case, 200w seems pretty low.

You may have a bad time, think upgrading it!
