Not really as they are proprietary. You could put in a second smaller ATX or SFX PSU in your MT (just below the HDD cages) to power a graphics card. Just run the power cable out through a back PCI opening in the case. A 350 or 450 watt is enough for a 570 or 580.
i built (installed a HD and OSX) a 8300 CMT for a friend and he used a spare PSU just to run a NV 1060 GFX card, i have also read about someone that makes a wiring harness that allows you to run after market PSU in the full size CMT 8300, i think he sells them on ebay.
It's best to avoid cables sold on Ebay. The quality is generally sub par. Some people have reported frying their motherboards with low cost adapter cables. The only ones I would attempt to use are from Moddiy. These are the only ones HP recommends (in their forums) if anyone wants to upgrade the PSU.i have also read about someone that makes a wiring harness that allows you to run after market PSU in the full size CMT 8300, i think he sells them on ebay.
I've run 1440p with no issues from HD4000 displayport and have driven ultrawide displays with no issues as well. I'm not sure what you are experiencing - sorry!Has anyone else experienced this and if so, were you able to fix it? It seems logical that if Windows 10 can easily use the proper resolution using the onboard video from displayport, and SwitchResX makes it work on OS Mojave using a PCI video card, that there should be a way to have Mac OS Mojave work with the onboard video.
That's one reason I don't suggest replacing those. HP doesn't want the end user to upgrade to higher wattage PSUs at all. Hence they make it rather difficult to do that.When I tried to physically put an ATX PSU in the CMT none of the bolt holes lined up - it was like the ATX PSU was a different size.
