I recently got my hands on a new 5080 graphics card, and I'm curious about using a pigtail connector with it. I plan on connecting that to my GPU's adapter, along with another individual cable. I've been using a similar setup with my 3080Ti for about four months without any problems. My power supply is the EVGA G5 Supernova 1000 watts Gold. Is this safe?

From my calculations, using a pigtail should work fine, but I don't recommend it for long-term use. There are concerns about adapter failures in the future, so investing in a native ATX 3.1 power supply is a better solution.
Yes, that's generally fine! Just keep an eye on the power draw and make sure the cables are rated to handle it.
If you're using a pigtail, make sure it's a dedicated 8-pin to 12vhpwr cable, as recent Nvidia cards have warned against using multi cables due to their increased power demands. Using a native 12vhpwr cable or direct PSU connections is the best route to avoid any issues.
While it might work in the short term, it's not the best idea. The 5080 pulls more power than the 3080 Ti, and using pigtails could lead to overheating or melting issues since those cables aren't really designed for high loads. It's safer to go for dedicated cables directly from the PSU.
Got it! What would you recommend instead?
So, just to clarify, using two connectors including the pigtail should be okay? Why do people say it’s risky?
