Tried support w/o success. I need to get some computational TFLOPS for an HP Z620. The 1660 TI (PH-GTX1660TI-O6G) seems like a good compromise between cost and horsepower. The Z620 has an 800W power supply but only 6 pin PCIe connectors headed out. Looks like I can deliver 150W to the card. I assume I'll need an 6-to-8 pin adapter which doesn't apparently come with the card. Will this setup work correctly as I'm going to really push the card as a computing engine?
