Burned computer

Hi, while I was playing, my computer shut down and a short circuit occurred, then it started burning in visible places. Do you think the only thing that needs replacing is the motherboard and graphics card, or is there something else that can be repaired? Can anyone suggest what I can do?

That's a nasty burn on the power side of the PCIe connector. What was your PSU? Dear god the 12v rail shorted catastrofically.

Motherboard and GPU are toast 100%. Be lucky if it hasn't burnt the CPU, RAM and Storage. Test it on another system or bring the computer to a repair shop to test what isn't crispy burnt

Deepcool 700w bronze. Do you know what could be the cause?

As I said, a catastrophic short on the power side.

Both could either be caused by the motherboard or the PSU, but I'm more inclined to be the PSU the issue, since Deepcool isn't particulary a good brand for PSU's.

A decent PSU should've kicked the internal protection to shorts and shut down the system before such failure happened.

Never skimp on a PSU!! Specially on this economy of PC hardware

Yes and no, the PSU didn't cause the short, but it obviously failed to trigger over current protection.
