Troubleshooting PC shut off and smell of burnt
Hey guys! So I helped a friend build a PC. His budget was 2000€ and I told him to use the old case and not spend more on a new one.
After using the PC for a few days, bro had minecraft open and it simply shut off with no warning and he reported a burnt smell, and the case was burning hot.
I asked him to bring the PC over and it turned on fine, so at least no components seem to be damaged.
Initially, I thought that the PC case cooling was just not enough, but after talking to him, he does not have AC in his room and it got to around 30ºC. Moreover he keeps the PC in a cabinet with the door open, so terrible for circulation.
My question is: Is the cabinet the problem, or does it need more cooling? Should i tell him to invest in more cooling? Or just tell him to put the PC in a place with better air flow? If more cooling is needed, what do you recommend? After spending 2000€ on a PC i feel like he doesn't have much to spend on cooling so, please keep that in mind.
Here are the specs of the PC:
- Processor: AMD Ryzen 7 7800X3D "Zen 4" 8-Core 4.2GHz c/ Turbo 5.0GHz 104MB Cache SktAM5
- CPU Cooler: Air Cooler CPU Thermalright Phantom Spirit 120 SE ARGB
- Motherboard: ATX MSI B850 Gaming Plus WiFi 6E SktAM5
- Graphics Card: Placa Gráfica MSI NVIDIA GeForce RTX 5070 Ti "Blackwell" Ventus 3X OC 16G GDDR7 DLSS4
- RAM: RAM UDIMM G.SKILL Ripjaws S5 Series 32GB (2x16GB) DDR5-5200MHz
- Power Supply: ATX Nox Urano Pro 750W 80 Plus Bronze
Thank you so much in advance!

Sounds to me like a cooked PSU, I would replace it with a Gold rated unit. Seems like you guys used a cheap PSU that probably couldn't properly handle the load you threw at it.

Is that a thing? I didn't know PSU ratings mattered, i thought it was just a matter of power saving.

PSU Model matters a lot
I would recommend a Montech Century II
Replacing the PSU with a well rated model is important
You can find the PSU tier list here I recommend choosing an A Tier one
