i see a tiny spark on gpu where the power connector attached....every time when i power on my pc..no smell or damage found
Ok so if you can attach a different cable to it (your psu should come with 2 sets of pcie cables). If it still sparks try the gpu with another psu/other computer that can handle it. If it still sparks return the gpu because then it's defective and has a high chance of breaking soon (catching fire, frying itself, breaking your whole pc,...).
I don’t necessarily know why that is happening but it lost definitely isn’t normal or safe. It might be your PSU but I would wait and not use the PC till someone with a little more knowledge tells you the exact cause.
