I am not here to complain or pretend that I deserve everything in the world. I am just humbly asking to hear your honest opinions. I have (had) an EVGA GQ 850 Gold and for some reason, it started melting the VGA port and cable. A bunch of bubbles appeared in the 8 pin cable that connects to the GPU 8 pin port. The damage extended partially to small part of my carpet; the damage could have been my whole house if it was not for my sense of smell. I called EVGA, they complied with the warranty by sending me another unit (for which I am grateful), but I think that should at least discuss replacing my GPU. I was simply told that they are not liable for the GPU, that I should go thru the GPU warranty.....and obviously not liable for the carpet. I am wondering what would happened if the house actually would have burned down ( which was very possible and I am not exaggerating on this)? Anyway, pics attached..... Thanks!

What gpu is it? That is vsry strange that the cable start to melt like that, and great catch on your part. Have you tested the gpu at all? Was there visible damage on the gpu?
Use two separate cabled if your card requires two 8 pin connectors or an 8 and a 6 pin.. especially if you are overclocking or using a high tier card. I wouldn't trust a wingle canle with dual 8 pin or 6+2+6, because the gpu is going to want more power than the single cable can technically provide.

Yes, I agree, but its not a particularly power hungry GPU and at that moment was not overclocking. The GPU, I used is a HD7990. According the AMD website, the recommended PSU is a 750W unit. That is the reason why I picked a 850W unit, to be extra safe.

Bummer to see this. Myself I always use two separate 8-Pin Cables, mostly for my own safety for what I use my cards for. Some times I will use a single cable with One 8-Pin and One 6-Pin though but only for a short time and for testing. What is the Make and Model of your AMD HD7990 Graphics Card? Can you post a Photo of the Power Connectors on the Graphics Card?

If the faulty power supply caused physical damage to GPU, they could use that as grounds to void your GPU warranty.
2016 seems to be the year of electronics burning/melting/blowing up.

It's the video card BIOS programming and it's voltage regulation components that dictate how much power the card is allowed to draw from both the PCIe slot and any 6-pin/8-pin supplemental power connectors. Specifically, PCI-SIG (industry standard) specs dictate that up to 75W (6.25A) can be drawn through a PCIe slot, up to 75W (6.25A) can be drawn through a 6-pin supplemental power connector, and up to 150W (12.5A) can be drawn through an 8-pin supplemental power connector, at 12V..Your video card likely failed for some reason and caused that by allowing too much current (Amps) to be drawn through the connectors and the PSU happily obliged, because it could. A single-rail PSU like an 850 GQ has no per-rail Over Current Protection which is great for stability, but it's a double-edged sword..A multi-rail PSU would have probably tripped the Over Current Protection before that damage occurred, that's what OCP is supposed to do..Intel writes PSU rules in their Power Supply Design Guides that should be adhered to and had done away with the multi-rail requirement some years ago due to more modern hardware demanding more power and hardware manufacturer outcry. Long story short = A PSU will supply only what it's asked to supply, up to a point, by the hardware, even faulty hardware..Almost certainly not the fault of the PSU.

I guess one has to become a computer and electrical engineer to not be afraid to use a GPU and a PSU. I read 750W PSU on the box of the GPU and assumed the 850w PSU would suffice, but wrong I was. The 7990 is out of warranty, so to the garbage/recycling bin it goes. I would post pics, but there was no physical damage to it. I stopped the burning madness on time, before the 8 pin connected to the GPU melted too. All I know is, the GPU does not work anymore since this event. Well, as soon as that replacement arrives, on sale it goes, and so the other parts of the computer. I will buy a prebuilt computer, probably a Mac and forget about building my own computer again. It is definitely not for me. Thanks a lot for your opinions, I really appreciate them. Good Luck!

I'm sorry to hear for your HD7990.
The worse thing is when no more warranty and hardware still work and than something like this happen and GPU die.
Bad luck.

I wouldn't blame yourself for faulty hardware acting up. The circuit board on our brand new Trane XV95 central Heat/Air furnace fried itself two different times within the first year.

I just had similar event and noticed that my VGA port and cable melted at the PSU. Its a P2 1000w PSU about 3 months old. So I'm digging through info now about RMA. So it looks like I will have to pay for postage, right? Anything else I should be aware of? I wonder if I should just get a new cable and clean out the melted port? Also, does anyone know why they use only 18 AWG cable for their pcie connectors? note PSU appears to be functioning, but one of the VGA ports is a little melt warped. Haven't done too many tests to confirm extent of damage. ok thanks for help below...

Great First Post p2andrew for 2017. Did you read Post #7 above? "Long story short = A PSU will supply only what it's asked to supply, up to a point, by the hardware, even faulty hardware..Almost certainly not the fault of the PSU." Maybe you should have created your own Thread as you do have a different PSU an unknown Graphics Cards an unknown Motherboard. The EVGA GQ 850 Gold PSU and the P2 1000w PSU are not the Same Power Supplies. Any Photos to show the damage you are writing about?

Bob's answer was great but I just want to add one thing. As Bob said that is a single rail psu and I find it odd that an EVGA moderator would suggest using 2 separate cables since that wouldn't make any difference. The only way that would matter is if the resistance of the psu cable was high enough, which its not, you could safely send like 30 amps through those cords. Like Bob said though, the fault was the GPU and it caused the psu to send too much power which caused a surge back down the line melting the connectors. EVGA's awesome customer service is still replacing your psu despite it not really being their products fault. If you want more help post detailed pictures of the graphics card after you remove the fan and casing. You most likely blew a capacitor and that's can be a cheap easy fix. Just need a capacitor which you can get from AMD and $10 soldering iron. GPU chip could also be fried then it would be done. Also its a good reason to always by EVGA they would have most likely replaced the Graphics card too had it been one of theirs even if outside the 3 yr warranty.
Also friends don't let friends buy Apple Computers don't do it!!

I have similar situation as you, but distributor on my country (Indonesia) refuse to replace my PSU
short story is, i buy a brand new two EVGA power supply 750G3 and 550GQ in June 2017, and then the 550GQ burned when i attach it into my motherboard and one cable is melted, i'm really sure that i receive defected product, so I return it to EVGA distributor in my country, but they refuse to replace my PSU, and tell me to post in this forum for warranty, what the??

your problem is you chose an evga product. ever since they did away with the lifetime warranty the quality has went to crap. second don't bother thinking you have a warranty of any kind with evga because you don't have one, they like to manipulate your registered product page in order to not honor warranties. I myself have 3 evga GTX 560Ti 448 core GPUs that were from rma on lifetime warranty cards but my product page claims I bought them from 2 different locations which is BS. so I have since ditched crapvga, and moved to an msi gpu on the current rig, at least till I can finally aquire the funds for the rest of the parts for my 1900x threadripper pc which I intend to use gigabyte/aorus for and im sticking with my lepa G 1600 watt psu. I know its way overkill but considering I have one that has been running 24/7 for 8+ years now I felt it was the best bang for buck option for actual REAL quality. friends don't let friends buy CRAPvga.
i am offended by your sig so you need to remove it.
