I burned my power source (Pixiv Fanbox)

I burned out the power supply of my main PC, the positive side is that the computer still turns on, the bad thing is that I don't want to turn it on and so my files are stuck on the hard drive.

I'm setting up my old PC to work from it in the meantime. I think it should be ready to work on soon, but I'll have to delay the projects that were stuck on my main PC until I get a new power supply.

I hope to be able to purchase a new power supply in a physical store in the coming days, or else I'll have to order it by courier (I don't know how long it will take)
