PCI-E slot died with RX 480

First-time poster here. I ran into a problem after upgrading my rig with an RX 480 today. Everything was working great but then after a 7-hour straight gaming session with Witcher 3 Blood and Wine (which by the way is AMAZING) I got artifacting and then everything went black and the sound cut out. I reboot my PC several times, but nothing would come up. After looking up the error code on the motherboard, I found that it was "No VGA present" so at first I thought the card was dead and I put back in my 750 ti, but it too would not work with the same error code. So I put the RX 480 in the second PCI-E slot and now everything is working just fine. After everything was A-OK I tried slot 1 again and it failed again, so now I'm in slot 2.

I did a Google search to see about this problem and I found several articles about the RX 480 overdrawing power on the PCI-E slot. HOWEVER, I'm not sure I'm ready to pin this issue on that yet, hence why I'm posting. I feel like having the card for just a day and only having a 7-hour gaming session is too soon to cause failure. What do you guys think? Maybe it's just a coincidence? I'm no expert on power draw or what overdrawing would actually do to a slot or even the motherboard as a whole. I also feel like if it was due to overdrawing of power that the whole south-bridge would get messed up and then the second PCI-E slot wouldn't work either, but it does work. I could be wrong in thinking that, though. Anyway, thoughts?

damn...i did suggest u try to undervolt to further reduce the dmg causes to your mobo 2nd pci-e lane.

If we overclock, surely it means more pull of wattage right ?

From what i watched online reviews, actually the standard for pci-e is more than 75w?

A lot of fear-mongering going on in the internet.

75W is the default specification for PCI-e. PCI-e can draw up to 2 or 3 times that IIRC (don't take my word for it, I didn't bother to look up the precise number). It is up to the manufacturer to specify the power draw and provide the circuitry for it. If you are using a decent MB, I won't worry about power draw.

Even the online reviewers were crossfiring, and runnining benchmarks for hours..nothing happened.

Maybe its for those running on low-end boards ?

so far only happens on PCI-e 2.0 boards.

I thought you posted about amd driver updates for that card to solve power draw issue? Don't you read what you posted?

Should wait for the update before using

did u read driver update on Tuesday (July 5, 2016). few more days till the issue is "solved".

Its also worth mentioning, there are other cards with far more aggressive PCIe power draw.

Not trying to portray a lesser of two evil scenario but this issue is far too overblown and its becoming confirmation bias.

Pretty sure he's talking to ts. Unless there are ts clones here.

Ironic statement is ironic.

Well, take this with a pinch of salt

And please, while I wish for this matter to be laid to rest, I have to intervene here because this claim was a wrong one from a redditor that misunderstood the specs. The limit for the PCI-E slot is unchanged.

Try that sustained draw and you will eventually burn your slot. Fear mongering wont result in burnt pcie slots, this kind of misinformation will.

PCI-E X16 slot draw a max 75W. Anything more would have to come from connector, either 6 pins 75W or 8 pins 150W.

Since when PCI-E itself can draw 2 or 3 times?? Basic common sense, if a PCI-E itself can draw 2 to 3 times more, why the need for power connector on a mid range graphic card??

Good point. I stand corrected.

Some good read here on this with details. Or just watch the YouTube there. http://www.pcper.com/reviews/Graphics-Cards/Power-Consumption-Concerns-Radeon-RX-480
