i was wondering yesterday. "What would happen if i unplugged the 6pin power cable from it, whilst it was on?" i thought this because i like to know things like this. would the computer somehow fry itself, or would it just rev up, and a quick restart would fix it with no problems. i am asking if anybody on this forum has ever done this or had any past experience. do not judge me, this is just a question.
It would turn off. When you plug it back in it would turn on again. The PC would switch over to built-in graphics when it turns off and switch back when it turns on.
It would most likely bluescreen (of course you would not see this as you would loose video) and then refuse to boot, because the pci-e can't provide the power needed. i'd not suggest doing this however since you could cause permanent damage to your hardware.
This is literally the exact same thing as asking "What would happen when I unplug my fridge?". It'll just turn off, nothing will explode.
really, ok. so it would not cause any perminate damage, if so ok that is good. i just want to know as i will literally do things without thinking and messing with computer hardware is one of the things i have been known to mess with --- Post updated --- how?
hmm, does it like throttle, like my CPU has two power connectors, once i only plugged in one of them and the CPU didn't turbo boost all the way, it was like a power limit imposed upon the CPU, then i plugged in the other connector and then all was well
It would blue screen, source: done it Neither amd or nvidia cards are equipped to switch power source at runtime. Their behaviour in undefined at this point and resulted in a driver crash in turn causing unmount of pcie device from the OS, something windows does not actually support and causes a blue screen. Neither my gtx460 or 1070 will power on without power connector in place. Yes there is the potential for physical damage as the vrms try pulling more current than they should from the mobo to account for power brownout, overloading both motherboard and vrm phases
If it didn't detect the second power connector to be missing then it would draw the maximum amount of current, which could pull too much on that connector and drag the voltage down, then the CPU would bluescreen from not having enough Voltage at the high frequency under load. I will try disconnecting the power from my GTX 960 to see what happens
