Update :
So took mine to the local gigabyte service center. The idiot over there was saying they cant give me a RMA as this looks like physical damage. Then found out another rep in India who was helpful (like Giga man). Finally got the RMA number from the service center. Then i get a call sometime back from Gigabyte saying they dont have the component needed to replace the connector block in India (isnt it like a 1 dollar cable ?) Also they told me they cant issue a replacement for now since there are no stocks. So they are issuing me a credit note and a full refund for my purchase.
Iam just going to get the refund and wait for a bit. This is such a botched launch by Nvidia and Gigabyte. I spent nearly Rs 91,000 on the GPU which is around 1235 USD (coz of customs, etc) and they make me run around. The worst part is that outside the UK, this issue is unknown to most retailers. For those who are looking to get this card, id suggest going for another brand (preferably Asus). Also before you buy the GPU, google " issues with that brand/GPU" and browse through diff forums before buying. Had i done that, would have saved a lot of time/effort. Gigabyte has screwed up the RTX 3080 experience for me.
