For a while now I have been wondering: "what would happen if I removed the 6 pin auxiliary power from my graphics card, while the computer is powered on?" This may sound ridiculous, but I have been asked this a few times and there seem to be no answers about it on the internet. So, my plan is to purchase a used graphics card from cheap on eBay and put it in one of my old Dell Optiplexs. I have conducted similar experiments before and they have not to lead to permanent system failure, however, I am not convinced the Quadro I have ordered will survive this experiment. I will not be using cutting edge technology for this, it will literally be an old Quadro from 2008 which came from a dell precision. 3 experiments will take place: unplug while on - power off the machine. unplug, and plug back in, while the machine is on if it stays on. power on the machine without the plug and put it in while it is on. so what do you guys think will happen? will the graphics card live to tell the tale? will it go pop? will it simply not output anything? will it be repairable?
I find these helpful to understand more about how GPUs are build etc: I think your greatest risk lies in removing and connecting power connector in a way that all pins connect and disconnect at same time. I would think that there might be issues if some pins connect at different times, so that positive is connected without negative or something like that. Somehow I would worry about PSU and other components more than GPU, but watch those videos and see what you can get out from them. Someone might ask if such experiment makes sense, but what we would do in name of science, craziest experiments are needed to bring sense to world.
Your system will crash (kernel panic/BSOD), and you'll lose video output. It may also emit a high pitched sound, a notification that it is not receiving power, which is normal. It is unlikely that anything will be damaged, as modern systems are fairly graceful when hardware changes occur unexpectedly.
I will be recording this experiment on Monday. The computer I have decided to use is a hp pro 3010. Or a Dell dimension e5520
only just seen this, but is that noise coilwhine or a speaker that dell computer (e520?) can have a bios update to 2.4.0 and cpu upgrade to c2q q6600 if required makes quite a nice machine if you do so
if you remove it whie the card is powered on it will just go blank and might damage the card because the power going to the card has been removed i do not recomend it it could damage the card sory for the bad splling im on a bad school, chromebook
i tried it and as can be seen from the video, it does nothing. it just powers off the card and it makes a ringing sound. plugging it in again makes it stop. resart the sstem and it will be fine. it is the same with dual 6pin cards and 8 pin cards
