Yup, I just saw these specs on the internet. It landed me on the same page links, and it looks like that your system is pretty decent, and it also has a compatible PSU as well. On the product page, it says,
""Support for two PCI Express® x16 Gen 2 or Gen 3 graphics cards up to 300W (total for graphics): ""
And since you plan to use the Nvidia GTX-1650 graphics card on this system, it should run fine since being a dual-slot card, the NVIDIA GeForce GTX 1650 does not require any additional power connector, its power draw is rated at 75 W maximum.
However, some custom AIB models do indeed require a 6-PIN PCI/PEG cable for the GPU. So just make sure your current PSU has at least 1 6-pin cable, should you plan to buy a custom variant card requiring this. But I'm almost certain it will have these cables.
The full database can be found here,
https://www.techpowerup.com/gpu-specs/geforce-gtx-1650.c3366 .
Even the current PSU in this workstation system has sufficient wattage for the GTX 1650. The specs say, ""825 / 685 W (input voltage of 100 VAC-240 VAC) "", and
Power Supply (externally accessible, toolless, 80 Plus® Gold Certified, 90% efficient): 825W or 685W
".
So based on this you should have no problem running the GTX 1650 gaming GPU as well. List of supported cars are listed as QUADRO, FirePro series, but you should also be able to install any gaming card from either AMD or Nvidia. I don't see any huge issue here.
