Lenovo Ultrabay Removable Graphics Card NVidia GT755M 2GB for Lenovo IdeaPad Y510p Laptops

These are Brand New and an official Ultrabay card from Lenovo, and ONLY work in the ULTRABAY slot of a Lenovo IdeaPad Y510p laptop THAT HAS AN EXISTING GT755M single card. This will NOT work if you have a system with an existing GT750M card. Note that you may need a larger power supply adapter (170 watt) from Lenovo if your laptop shipped with a smaller one - this card will not work without the higher power supply. You may need to contact Lenovo Technical Support to get assistance in setting up the drivers and SLI configuration once you insert the Ultrabay card.
