Your PSU will be bottleneck. To find right wattage, please enter your details here: Please select Basic option. Expert option might be overwhelming https://outervision.com/power-supply-calculator

1660ti require power connector 1*8-pin which draws 150W So, your Graphics Card will drawing total 225W (including from PCI-Express) You have not shared the other PC Configuration like Processor, RAMs and HDD/SSD details. So, cannot answer about total wattage. Btw, You can enter your details and check the exact power consumption online from here: https://outervision.com/power-supply-calculator Apart from that, No doubt Antec VP series is good one [Personally using 700W Model] but it's the cheapest PSU in Antec range. So, I won't recommend stretching your luck on 500W Model. Source: 1. Power Connector: https://www.techradar.com/news/best-nvidia-geforce-gtx-1660-ti 2.
