What happens if you try to use a power supply with insufficient power output?
I bought a desktop about 4 and a half years ago. Later, I installed a dedicated graphics card, but it required a 400W PSU, so I bought a cheap 500W PSU to replace the existing 300W one. Now the 500W one is dead, and I’m wondering what would happen if I reinstall the old 300W PSU without removing the video card. None of the computer’s components are really worth anything to me, and I probably won’t actually do this; I just want to know what would happen if I tried it.
What happens if you use a 300W PSU with a video card that requires 400W?
