Power supply fried graphics card

[jingkai.xie007]

Hi there! Few days ago, my pc turned off while I was playing PUBG, and I couldn’t turn it back on. After many searches I did online, I found out that if I unplug graphics card from power supply , my pc works fine, so I concluded that the graphics card has been fried. I am planning getting a new graphics card(gtx 1070 or beyond), so my question is: if the power supply is still safe to use?

My power supply is EVGA 600b 600w 80+ bronze, and my pc was 2+ years old

just got the new power supply, connected to everything except for GPU, works fine. then I connect my GPU to PSU, my pc didn't turn on, lights on my case flashed, and then there was smoke coming out from my GPU. so I turned off power supply immediately. so it was indeed GPU problem.

Which is EXACTLY why I said we don't like to assume something is bad until we can prove that either it IS or that everything ELSE is good. Seems jankerson was jumping the gun, not the first time either, and would have you convict a part that was not in fact faulty. REGARDLESS that the GPU card you are planning to get really ought to be paired with a better PSU than the one you originally had, the fact remains that it was the card, not the PSU, that was faulty, and had you not planned to upgrade to a higher end graphics card, replacing the power supply would have been a waste of money and time.

Lesson learned, for some people at least. In the future when you ask for help and somebody attempts to help you, might be worth you while to at least entertain the idea they might know a thing or two rather than simply blindly listening to those who want you to throw parts at it or upgrade unnecessarily. Glad you got it sorted either way, if in fact you have, which remains to be seen once you get a new card.

Hopefully, installing that new power supply and connecting it to a faulty card did not

A. Damage or destroy your new power supply.

B. Void your warranty

EVGA comes with standard 3 year warranty. Have you checked with them?

I checked my serial number on the back of my card on EVGA website. it says it is out of warranty...

I guess that's one reason not to buy prebuilt.

Actually both the GPU and PSU were suspect from the start.

The old PSU could have cooked the GPU.

So to actually check the PSU it would have to be loaded up with another GPU to see if it was good, not something I would want to risk hooking up a $400+ GPU to a suspect PSU.

Or

What I recommended, replace the PSU, the better cheaper solution that would have been replaced anyway.

It's not like MOST people have extra GPU's and PSU's sitting around to test things, I do have spares for testing personally, both PSU's and GPU's. And also a few test machines. The benefit of working on thousands of PC's over the years screwdriver in hand.

What I recommended was nothing different than what I would have done here. 1st thing I would have done was hook up the graphics card to a known good PSU.

In the end the GPU is DOA and the old PSU is still suspect as it hasn't been tested with a good GPU. I would just trash the old PSU being what it is personally.

Making excuses does not change the fact. I don't know why you are finding it so hard to accept and admit that you offered bad advice. It happens. I've done it myself in the past and will probably do so again sometime or other.

No, the PSU does not need to be connected to another GPU in order to test it. Power supplies can easily be tested under load using fans, automotive light bulbs or load specific fixed resistors. All are cheap methods anybody with a multimeter and a few dollars can do.

This too, is wrong. It's NOT the better, cheaper solution. The better cheaper solution is always to replace the component that NEEDS to be replaced. Not the one you FEEL should get replaced because you don't like it or are guessing.

I would just trash the old PSU being what it is personally.

THIS is why you suggested replacing the PSU from the start. Not because it was the primary suspect. Not because there were indications that it might be faulty. Not because the system was displaying signs of power supply failure. ONLY this, and nothing else. This is not how knowledgeable technicians or enthusiasts identify and fix failures. This is how untrained persons fix failures based on not being willing to put in the work necessary to properly diagnose and repair the problem that actually exists.

I'm done here, but you were wrong with your knee jerk recommendation and we both know it. Let's move on.

I concur with your comments here.

I'm using an EVGA 600 B1 80+ Bronze 600W power supply as a replacement in my old 2009 model Dell XPS 435T i7 940 system to run it along with my MSI GTX 1060 6GB video card. The one thing I was careful about with this power supply, after reading good reviews about it, was that it offered at least 20A on the 12v rail for my GTX 1060 - it offers 49A.

Been running this power supply for over 2 years now without issue. It only has a 3 year warranty, and that usually means it won't live much past that time, but I will have built my new computer before that, anyway. The old Dell will become a retired backup.
