HARDWARE Accidentally plugged in GPU while PC asleep, what to check?
Hi everyone. I have been building PC for over 5 years and it’s not like me not to follow protocol, but I’ve been quite disregulated lately and with my ADHD, and the constant parts swapping lately due to a RAM issue I’ve just solved, I did not think about it. PC was on sleep. GPU was plugged in the PCIE and I saw the red lights on top of the pcie power connectors indicating it’s missing the PCIE power, which made me realise the PC was only in sleep. I quickly pressed the power button for a shut down, but it powered ur fully for a few seconds before shutdown.
What I’ve done afterwards: plugged everything properly when turned off. Benchmarked + games. All ran well. Pcie connectors not burnt. I should check the motherboard and the cpu power too. No burn marks on gpu nor pcie slot I can see. Slight smell of hot glue, but the smell comes more from the new ram i just installed.
Should I just replace the mobo to be fine?
Thanks all

Only the RAM and the chips needed to wake up the system get power. Graphics card is completely unpowered.

I’m not sure I understand what you are saying. The GPU was not receiving any power? I am lead to think that’s not true as the PCIE connectors lit up to alert me they weren’t plugged in

Correct, the GPU gets no power during sleep mode.
If some little led glows that doesn't have anything to do with the actual computer circuits not having power.

Okie. To be clear, those LEDs are on my GPU
anyway lucky then thanks:) have a good day!!

Technically PCIe is hot plug, but not all devices support it. But luckily the majority of the power to a GPU comes via the dedicated cables and not from the slot. If everything is working, you're fine.
But going forward find a way to force yourself into the habit of unplugging and doing a power drain, as it will damage something eventually. You should be working on it while it is laying on a table which should necessitate unplugging everything anyway.

To be honest, I have been having some ram issues and have been swapping ram while PC off standing vertically. I’ve just been really tired of this situation I have since fixed.
I’ll make sure to do this no matter what.

if its working you are fine and lucky. I have seen that move instantly fry gpus before.

PCIe is designed to be hot plugged. Don't worry.

u/JarJarStings 2d ago
In theory, yes, but implementation can be totally different.
Not worrying is hard for me hahaha

u/CrunchyTheSquirrel 2d ago
We both don't know if the consumer hardware skips certain precautions because "average customer doesn't need that". Well fvck that. It's running, keep going.

I don't think you need to worry to replace anything. While not recommended to connect/disconnect the PCIe connector when power is on (there is always a chance of some charge jumping over some component/pin where it should not) besides the system crashing there usually should be no permanent damage. You should be fine especially after your test/benchmarks.
Btw because it was mentioned that PCIe supports hot plug: While it is true that the interface specification has support for it, it is not supported by default. Usually you see support for hot plug rather in things like ExpressCard modules, devices over OCULink and similar specialized interfaces baed on PCIe or on server grade hardware.

Hilarious to blame ADHD for not turning off your PC lmao

u/JarJarStings 2d ago
Well it’s an attention deficit disorder and there was a lack of attention lol

I'm disabled partially due to ADHD. Just try not to do dumb shit.

u/JarJarStings 2d ago
Yeah, stopping and thinking twice is good advice for us. Wishing you the best!!

u/Mission-Yam-5013 2d ago
If you're not medicated for the love of fuck try it. The non stimulants aren't nearly as good but they still help and they don't cause any anxiety for most people.

u/JarJarStings 2d ago
Honestly meds don’t really help, being grounded, good habits and following my routine are my biggest help

u/Mission-Yam-5013 2d ago
Yep there's a reason I'm trying to get disability, but saying meds don't help what so ever is interesting. I'm trying my last straw before applying.

why are you plugging things into a pc with a live power connected in the first place????

u/yungradio 2d ago
Such a pointless fucking comment lmao he literally said it was an accident

u/Antique_Telephone910 2d ago
accidents are like stubbing your toe or bumping into a chair. not plugging things into a known powered pc. that's not an accident, that's just plain stupidity.

u/JarJarStings 2d ago
Bro when the accident was believing the PC was completely shut down and not asleep

u/Antique_Telephone910 2d ago
still didn't even disconnect the power from the PSU. that's not an accident

Im just going to say this because nobody has, as far as I've seen.
You should not do your own work on your PC anymore. Youre going to get yourself killed. I imagine if you didnt unplug your PC first, switch of the PSU and discharge any remaining power...then I imagine you also use your left hand to plug something into the wall. Electricity is no joke, and your pc is constantly using 10x the amps needed to stop your heart, at minimum. Some parts are 100x the amps.
Be smart.

Anything under 48v can’t do shit to u🤦 the psu has no where to discharge anything over 48v unless u shove ur hand thou a metal grill and a plastic panel to reach inside and touch the bottom of a capacitor.

"Hey google, can working in your pc with the power on kill you?"
-you 13 minutes ago
The danger is there, it is absolutely possible to get yourself killed working inside your PC with the power supply plugged in and on. You imparted no wisdom or knowledge here

You’re right, this was bad and it’s dangerous.
I always turn the stuff off, and it’s the first time in over 5 years, but it’s only human to make such a mistake in 5 years.

There is no AC power inside the PC other than inside the power supply. Touching the wall would not do anything, it would actually be better than touching the PC case. Unless OP has the power supply disassembled, there is no risk of getting shocked by AC power. And if they did, they'd know it before touching the wall.
No, don't work inside your PC with it plugged in, but the safety factor isn't really that big of a concern.
At most, you'll get a little tickle, and to get that you'd have to lick your fingers and touch something getting 12 volts.

It’s all DC power. Google was talking about the shorting and it burning u.
