So today I went out and purchased an MSI 2080 Gaming Trio GPU, I got home excitedly just to find out my cables are wrong, I have one 6+2 pin cable and it requires two 8 pin, little backstory, I bought this computer prebuilt from cyberpower, probably 6ish months ago, some claimed it was easily upgradeable, which up until now I've had no issues, anyway I go to see if I can replace the PCI-e cable, and the PSU is non-modular, is there anything i can do to get this to work? Or am I going to have to buy a new psu and reroute everything?
