I find that strange. I have purchased a fw products from PNY and had a somewhat similar experience that turned out positive.
The exact same GPU failed me after 1 year and 5 months.
I submitted a claim and PNY honored it straight away. The only requirements that had to be met were.
Product registration when I purchased and provide them with a copy of the original invoice.
Once that was done they sent me a refurbished GPU that served me well till I sold that unit.
Yes, it was refurbished and not brand new but they did honor the warranty as welas sent it our with a return label for the faulty GPU.
Maybe I got lucky I don't know.
