New Vega64 burnt plastic smell?

    Hi guys, i'm not really sure where to go with this question but i thought someone here may have knowledge in the matter.
    I just recently bought the Saphire RX vega 64 nitro+ from overclockers. I am running it with a ryzen 1600, 16gb ram and one ssd. My power supply is a corsair RM 750x.
    I have noticed whilst playing not very demanding games like rocket league that a burnt plastic smell starts to come from inside my pc and it also becomes very hot.
    The smell seems to either come from the PSU or the new vega card but after swapping back to my old r9 390 card i have not experienced the same issues.
    My pc is not overclocked in any way and i'm not sure what would cause the card to do this other than the power supply possibly being overloaded but my thoughts would be that the power supply should be able to handle the card. I have also given the pc a thorough cleaning and removed all dust.
    I tried monitoring the temps with the side off/on and the temperatures seem to be sensible enough except for the fact that the card is creating the same temps on less demanding games as it is for more demanding ones. Any ideas or recommendations would help. Thanks [​IMG]

    Check for any burnt power connectors. Not just the ones for the GPU either.

    Have you taken the plastic film off the backplate?

    Are you using the correct leads from the psu? And as above, unplug and check for burnt power connectors.

    I've checked for burnt connectors and haven't noticed anything iregular. There is no plastic film anywhere on the card. I'm currently using an 8pin type4 connector with 2x 6+2 pin coming off it into the card. I have also tried running it with 2 8pin connectors coming from psu.

    I'd not be happy - you absolutely sure it's coming from the GPU and not the PSU or a short somewhere? I'd RMA it if I took it out, walked into another room and the GPU still stank.

    I'm not 100% but there doesn't seem to be a smell when using my old card. I don't have a spare power supply to test it on that either. I've even ran it through a wattmeter under load and there was plenty to spare so i'm pretty sure it's not the power supply. Is there a chance that the thermal compound can cause an odd smell when the card is hot? I ordered the card just over a month ago and it is only recently the smell has become more frequent/noticeable.

    Use separate connectors from psu to card

    Gotta do the smell test. Does the card alone smell of burning at all?

    Burnt electronics has a pretty distinct smell.

    This x2.

    You have to run separate connectors - the power draw of a vega 64 is too much for a split cable.
    The burning smell is your cable - throw it away and use two 8 pin connectors.

    Worth inspecting the PSU cables or connectors to the GPU if there's an expansion.

    If they've got too hot, then that'll cause some burning smell. Look for any bubbling on the cable sleeve.
