I bought my MSI 1080 ti back in June and was in LOVE with the results. It ploughed through the heaviest games I threw at it, and tolerated HUGE scenes in 3d animation programs well worth the update from my old 980.
Two months after purchase however, I steadily began to experience total failures more and more frequently, fans boosting to max while my monitor lost all input, requiring a restart.
Never needed to RMA a part before, but it seemed due that I'd hit some bad luck. Handed the card in to the local MSI in Industry and got my replacement weeks ater, back to full tilt.
...Then a week back, AGAIN my GPU starts to fail. Not failing output, but causing driver crashes, and this time it happened all at once like a switch flipped. Anything that required 3d rendering, even an empty 3ds max infinite plane, would cause the driver to fail and recover after crashing the program.
Furious, I prepared to RMA again, but after hearing sometimes that these things were the result of power failure, I impulse bought a new EVGA Supernova 850 Gen 2, which was listed on sale for only about $100, slashing a third of its price. I've been planning an upgrade to Threadripper for a while now, and already had this PSU on my wish list.
Got it and installed it the morning before, delighting in its modular design and avoiding intense cable management of a rats nest. Powered it in and just to humor myself opened 3ds max.
Shocked, I opened a heavy Max scene file, booted up a Unity engine game, finally settling on Rise of Tomb Raider. No frame loss, no crashes, it just WORKED. Even the benchmark worked.
I haven't had any opportunity to test it further, but... could it have actually been my PSU slowly failing?
It's an older Corsair 750 watt I bought back in 2010 or so, but it's shown no signs of failure, and should HANDILY power the 1080 ti. The EVGA only puts out an extra 10 or so amps to the 12v rail.
The only PSU failure I had before was the unit going out like a lightbulb, and that was over a decade ago. Can a PSU supply less and less power to a specific rail sporadically? In which case, why would my replacement GPU work immediately and take all this time to lose power and screw up again? Or is the GPU still defective (twice in a row) and just likely to fail again after whatever culprit sets it off again?
It's possible. I've heard of that graphics driver error coming from a PSU that wasn't too weak.
I mean, if you replaced the PSU and it fixed it, I guess a new psu can fix a gpu.
I'm sure the mobo makes the most use of the psu so yeah it was probably dying.
A failing PSU can cause issues like that, if the GPU cannot draw enough power other parts are likely struggling under the load as well. Which could cause all sorts of problems.
That is why whenever shit goes wrong on PC's I always check the PSU first, then go from there. I've only had once instance that my mobo went bad on its own due to a power surge. Other then that, failing PSU's have caused issues for me. I've had a PSU that lasted nearly 10 years over multiple builds fail and it caused me problems.
Yeah, my previous PSU would cause driver crashes, bad performance from time to time and red screens, and the issue would go away randomly. Getting a new PSU fixed everything.
