| AMD RX 6600 XT | 165 W | 8 GB DDR6 | *Dual SATA to PCIe adapter |
| NVIDIA RTX 2070 | 175 W | 8 GB DDR6 | *Dual SATA to PCIe adapter |
| NVIDIA RTX 3060 | 170 W | 8 GB DDR6 | *Dual SATA to PCIe adapter |
| NVIDIA RTX 2070 Super | 215 W | 8 GB DDR6 | *Dual SATA to PCIe adapter |
| NVIDIA RTX 2080 | 220 W | 8 GB DDR6 | *Dual SATA to PCIe adapter |
Please note that upgrading to a more power-hungry GPU requires a better PSU. However, in most cases, this may not be possible because most OEM pre-built PCs have motherboards that use a proprietary power connector. Nevertheless, this problem can be solved by using a power adapter. The more challenging problem arises when the model has a non-standard chassis or power supply, in which case upgrading the PSU becomes much harder.
