8GB The card has not been opened from its box, I haven't touched it, and I haven't done anything to it. The box is factory sealed. The reason is that I intend to gather a respectable amount of money + I have a power supply that is suitable for the card. For those who intend to buy both pieces together, for your information, the power supply is also factory sealed, not opened from its box like the card.
