So I recently started building a pc by buying new or second hand parts. The motherboard is second hand but in brilliant condition. I had all the parts and plugged everything in and it seemed to start up. 5 seconds later it completely shuts down and proceeds to restart. After some careful online research, I concluded that the psu was not providing power to the 8 pin conection on the motherboard and so I spent another week buying a cheap psu from my local Saturn. I get home and plug everything back in. The thing powers up but again goes into the 5sec boot loop. Frustrated, I flick a switch on the back of the psu which had 230/115 on it. A sudden pop, sparks and a broken fuse for all my room sockets. There was NO smoke. On closer inspection I find the motherboard is looking ok with nothing out of the ordinary e.g. melted solder, burn marks or popped fuses. I concluded that the 8 pin was faulty ON the motherboard and went about my day praying that the cpu and gpu are ok. Im thinking about getting a new motherboard but on close inspection of the current motherboard I found that it has a z87 chipset (best for the cpu line) and on amazon it is waaaay out of my price range. So now I'm thinking if it's possible to somehow repair the 8 pin conector? This would be so much better than getting the bottom of the barrel €50 motherboard and I want to keep this a's cheap as possible

There are a lot of problems here. First off, you're all over the place, it's hard to pinpoint your problem as you haven't listed anything about the specs, the budget, or the purpose of this build. Second, you seem to be assembling this by just throwing it all together, like croutons into a salad. And it sounds like you're using literal garbage power supplies in this build, which complicates matters, especially when you're just hitting switches for no reason. It wouldn't be shocking if you've already caused serious damage to your components.

So let's start at the beginning, with a list of your parts.
