Only plugged in half of the power connections to my GPU by accident. Left on for four hours. Was there any permanent damage done?

post #1 of 7
Thread Starter 
Not sure if this is the right forum here but this is what happened.

I just built my computer and I put in my gpu (r9 390). I only plugged in the 6+2 power supply from the PSU like an idiot. After I turned on my computer, device manager and my mobo bios failed to detect the gpu. However the light on the gpu was on but no fans were spinning. I then noticed my network adapter failed, and then a pcie soundcard i'm using failed.

In device manager I had device error code 10 "This device cannot start" on my network adapter. On my sound card I had device Code 12: "This device cannot find enough free resources that it can use". Are these just power mitigating functions the board will do to save itself? Cause I assume if I only had half the power plugs in from the PSU the 390 was trying to draw the other power it needed from the board?
A couple other sources online said it could possibly damage the board or even worse fry any parts attached to it.

Once I realized that I needed to plug in both the 6 pin AND the 6+2 pin supply for power to the gpu everything seems to be working properly now but i'm just wondering if any permanent damage could of happened. Any explanation is helpful, I couldn't find too much info on what could happen if this occurs on the net.

your system will be fine, once I totally forgot to connect power to my gpu.
and worse, one time I did not have my 24pin pushed all the way in and every thing went crazy, gpu fans at 100% case fans at 100% screen flashing etc, everything turned out fine, I'm using the system right now since 2010.

Thanks for the reassurance! biggrin.gif It'd just be such a bummer if I screwed this all up before I even got to use it .

This.

Actually not plugging in a GPU at all is safer than plugging in only 1 input (I would think). With 1 power source plugged in the card will likely try to power up and hopefully will have some safeguards in place that keeps it low clocked or something instead of blowing up.

There shouldn't be any damage if it was stock clocked and never went into 3d clocks. the 8 pin can supply a lot of power as well as the pcie slot. I would expect it is OK.

I should mention when this was going on, I was running the PC with the integrated graphics and the card was not registered in the device manager at all.

Here is another dumb move I did on my current system, I was installing a fan power cable extension on a fan with the system running redface.gif and I dropped the end of the cable that had the power pins exposed, it hit the bottom of my case and made a big spark, the other end was connected to my northbridge fan on my motherboard. and still everything is good and the fan header still runs the fan.
computer systems now days are pretty good about protecting themselves from our goofs. but I do know now not to touch anything in my system until it's powered off and I turn the power supply switch off also.
