Right now I have 8 4MP and 4 4K cameras running BI on a Dell XPS 8930 w/ I-7 8700 cpu, 32GB DDR4 ram, 6TB WD purple hdd, using onboard graphics. But I plan to have 16 4K Cameras running on BI on this same machine. Problem is the original 450Watt power supply has gone south. So I'm looking for an upgrade. Currently I'm looking at a AGV Series 750W Power Supply, 80 Plus Bronze Certified. Would this be adequate for my setup. Would something in a Gold or Platinum certified PSU be better for this setup? Also would a dedicated video card be called for to handle 16 4K cameras. If so, any suggestions for that would also be greatly appreciated.

450 Watts is more than enough on a PC like this, if you don't have plans to add a GPU to the system. Even with adding additional cameras, as they don't draw any power from the PC, and Blue Iris won't have additional power demands with more, either. Even with a dedicated GPU like a GTX 3050 that draws about 70 watts, 450 watts would still be more than enough in your system.
Prior to the demise of the PSU when I opened BI the processor usage would go from around 10% or 20% to 100%. And processor temp would Spike to just below 200ºf. Then hover between 175ºf and 190ºf. On closing BI the usage and temperature would almost immediately go back to normal. Around 125ºf to 130ºf at idle. I'm sure it has to do with processing existing cameras bandwidth. And will only be worse if I go with the new camera setup. I went with BI and a PC because I just didn't like the nvr software. But I suppose I could go back to the nvr if I can't get the temps under control. But the nvr presents another whole lists of problems. I even returned it to the manufacturer and they couldn't fix it. So they sent another one to me and it was no different.
