[SOLVED] GPU Fans twitching and no signal

[Bulius]

My 980ti's fans are constantly twitching over and over again and it doesn't produce a signal. I plugged in another gpu to the same motherboard and PSU and it works fine. What could be causing this

Cpu - I5 9600k
Motherboard - H310-HDV
Gpu - 980ti ftw
Crucial Ballistix 8gb x2
Psu - 650 watt Power Spec 80 plus bronze

If you install another card and it works fine, then it can really only be the graphics card is dead.

Just out of curiosity though, what is the model of the other graphics card you used and what is the EXACT model of the power supply in use, and how old is that power supply?

msi gaming x 1660 super

and a Powerspec 650watt model: PS 650BSM it is a few months old

I'm wondering if it might be something with the power delivery on the actually card so maybe I can replace it.

Also it was in an old z390p motherboard before something caused the rgb header on that motherboard to short and ever since then it has been acting like it is not receiving power, the gpu heats up but there is no display.

From my PSU recommendations page:

The Powerspec units sold by Microcenter are a mixed bag. Some of them are fairly decent using the same platform as the Sirfa High power Astro lite platform, so not total dumpster fire type units, but not particularly good either, and some of their units are simply garbage and should be listed below in the DO NOT USE category, but I'm leaving them out because there are really no reviews of them and since there are a few units from them that are ok-ish, I'm giving them a "use at your own discretion but buy a better model if you can" grade.

Even a gray label Corsair VS unit would probably be an upgrade from one of those Powerspec models, and a CXm or 2017 CX would, almost certainly would, without any doubt.

Certainly there ARE some good units out there that you won't see above among those I've listed, but they are few and far between, much as a hidden nugget of gold you find in a crevice among otherwise ordinary rocks and don't EVER assume a unit is good just because of the brand.

If you cannot find an IN DEPTH, REPUTABLE review on Tom's hardware, JonnyGuru, HardOCP, Hardware secrets (Old reviews by Gabe Torres), Kitguru (Only Aris reviews), TechPowerUP, SilentPC crew or a similar site that does much more than simply a review of the unboxing and basic tests that don't include reliable results for ripple, noise, voltage regulation and a complete teardown of the unit including identification of the internal platform, then the unit is a big fat question mark. It is best to avoid question marks when it comes to your hard earned dollars, whenever possible.

I recommend not trusting such units as companies generally always send out review samples of any unit they feel is going to get a good review, and don't send them out if they know they are going to get hammered by the reviewer. No review usually equals poor quality. Usually.

Since the 1660 Super only needs a decent 430w or higher unit, and the 980 ti needs a good 600w unit, and THAT particular power supply isn't very good, literally, as it's labeled as a "650w unit" on it's box and at the top of it's label, but the specifications sticker on it clearly shows it is only capable of 585w meaning that it clearly is a POS, I'd say there is a VERY GOOD chance that it is simply the power supply. As you said, power delivery, just not in the way you thought.

There is of course always a chance that if something else got shorted and zapped, that the graphics card did as well, but since this power supply is pure junk and should be replaced anyhow, I'd replace it FIRST before convicting the graphics card.
