Need new PSU for my GTX 780Ti

[FunkyFresh_]

So before I've had a GTX 750Ti and I got a 780Ti today. However, the PSU I believe doesn't have sufficient power to power the graphics card and I'm wondering which PSU I should be getting since my current PSU also doesn't have the cable/s necessary to fit in with the GPU. Could someone tellme which kind of brand and connection of a PSU I should be getting in order to both fit my case and power my GPU. If necessary I will post photos for you guys. Thanks

A budget, location and a preferred site for purchase and a list of your full system's specs would be a good starting point for us

List them as:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

CPU: i7 4790k 4.2 GHz (not sure if OC)
Motherboard: Gigabyte GA-Z97-HD3
Ram: 8 GB DDR3 (Two 4 GB sticks)
SSD/HDD: Corsair Force Series LE 240 GB SSD
GPU: GTX 780Ti
PSU: Not sure which one this is, but here's a picture of it:

Chassis: It's a really old one and it doesn't have any sort of model number so I don't really know either but here's pictures of it

OS: Windows 10 Enterprise

My preferred place to buy would be NetOnNet since I can't really order and this is the only place I really can go to easily, I live in Sweden in the city of Helsingborg so that you can see if they have any PSUs in stock in that preferred city. My budget would be pretty much anything as long as it's not over 100 dollars pretty much

(Sorry, if I wasn't much of help, I'm not a professional in these kinds of things).

I fixed your image links and their tags

You're going to need about 750W of power for your system to give you some headroom with overclocking since you own a K suffixed i7. You're going to need an aftermarket cooler to perform an overclock on that processor though.

Can you afford this unit?

Yes, I think I can but would this one suffice or it won't fit my case? Or the connections don't fit? https://www.netonnet.se/art/komponenter/nataggregat/modulart/evga-supernova-750-g2/202020.9009/
