GPU Failure , Did PSU caused it ?

[Hamza93]

Hello everyone , i m not much of an expert , i m new to the computer and tech knowledge , so story goes like this , i bought an HP Z400 system and bought a used Gigabyte HD 6850 1GB , it looked quite used but when i performed 3 4 times heaven benchmark , it seemed stable , the psu is delta 475 W 80 % efficient bronze , 3 months back i was playing GTA V with high settings and then i shifted to NFS RUN on high settings and before previous night i was doing heaven benchmark test too to note temps , now as i ran NFS RUN , the system restarted and screen got blank and then suddenly HP logo appeared and graphics driver failure or not found was stated on the screen or something like that , and there were 2 blue large vertical lines on the screen ,i took out the GPU and was cheking it and then a screw fell of and the plastic was moving much , i didnt notice that before , quite strange , i contacted my friend as he is into computers , he told me that he has a friend who can fix gpus , i know that the only way was reballing i guess but i gave him the gpu , he got it fixed and i m running it now , in these 3 months i have completed 2 3 games on medium settings to high now , like GTA V , NFS MW , WITCHER 2 Etc and so on , havent used the GPU everyday since it got fixed but have done 5 6 hours gaming on it 2 3 times a week ,everything else also seem ok in the pc , i installed gpu back on the same slot , my friend said that may be the PSU have caused it due to an electrical spike or some other reason in PSU or may be the card died on its own but not sure what must have happened , it died after 2 months of buying it.
i checked with the watt meter and gaming wattage is around 250 Watts , card running alright now though temps are around 70s in gaming and i also did a little setting of one of the fans as it wasn't spinning fine much , what do you suggest as i m looking forward to an upgrade to 1050 Ti , just worried that is it safe to install , what to do and secondly how much life can be expected from a repaired card .

Thank you

System : HP Z400
Psu : Delta 475 W 80 % efficient bronze
Ram : 8 GB
GPU : Gigabyte Radeon HD 6850

yes it most likely was the PSU the cpu has a TDP of 130w and AMD recomends at least a 500w PSU for that graphics and this 500w is most likely for a 65w CPU which would put the system usage of power at around 550 watts when the PSU is rated at 475 which means sometimes the PSU will try to increase its output and can damage the system replace the PSU as fast as possible for one around 550w or to play it safe 600w

There's no reason to get a 550W or 600W PSU let alone change the one he has now.

That was one very long sentence. It's a lot easier to read if you broke that wall of text into two paragraphs with sentences.

So I don't get it. GPU was broken, got it fixed, now everything works. So sounds like your GPU was the problem.

Thank you for your replies , Actually the PC wattage is around the 250 watts to 260 watts on gaming so i don't think so that the PSU is under any load as i have checked and tested that with many games , it has a headroom of at least 200 watts if during games sometimes it peaks 275 watts for some minutes.
