@soumenmaji there are actually quite a few but these are the common ones:
GPU upgrade options for Lenovo ThinkCentre M82 Tower with the stock 450W power supply
GPU Power consumption Memory Req.
NVIDIA GTX 1660 Super 130 W 6 GB DDR6 *SATA to PCIe adapter
NVIDIA GTX 1660 Ti 125 W 6 GB DDR6 *SATA to PCIe adapter
NVIDIA GTX 1070 145 W 8 GB DDR5 *Dual SATA to PCIe adapter
NVIDIA RTX 3050 130 W 8 GB DDR6 *Dual SATA to PCIe adapter
* Typically, the stock power supply in a business PC does not have the necessary 6 or 8 pin connectors to power the GPU. In such cases, you may need to use a low-power GPU or a SATA to PCIe power adapter. Alternatively, you can change the entire PSU. from [https://www.hardware-corner.net/desktop-models/Lenovo-ThinkCentre-M82-Tower/#:~:text=You%20can%20upgrade%20Lenovo%20ThinkCentre%20M82%20Tower%20with,in%20the%20chassis%20and%20the%20PSU%20power%20rating.|here]
