My stepson and I are trying to build a pc to use with the upcoming Microsoft Flight Simm. His out of state Grandmother sent him the following items from Best Buy and returning is not an option. I have been trying to fit the XFX AMD Radeon RX 590 into the HP ENVY Desktop. I quickly realized the power supply needed to be upgraded and have the EVGA 600W ATX. I am able to get the video card seated in the motherboard however I am stuck on how to connect everything. I did some searching and thought I needed the 24 pin to 6 pin connector (I bought this on Ebay). I am still not able to make the connections needed. Has anyone done this (i did try searching on here), or is this not an option to add the video card to this pc? Money is tight as his mother is off work due to the pandemic. Any help/suggestions would be greatly appreciated. Thank you in advance.
