NVIDIA Tesla Referral T4 Graphics Card PCI-E Model:PG183This is a data center Tesla Referral T4. It does NOT requires a special adapter power cable to connect to an ATX power supply in a workstation. It uses 70w-75w from the PCIe x16 motherboard port. It has 16Gb of VRAM. I know people have been able to successfully run these in the right kind of workstation for an AI stack. Unfortunately my motherboard just does not handle the card from a BIOS perspective. Do your homework before purchasing to be sure it will work for yours. This package includes the T4 card only.
