I'm interested in installing a GPU that has an 8-pin connector in my HP workstation, but it currently has a 6-pin connector. My PSU specifications show that it has a +12V output of 18A on the rail for the 6-pin. I want to know if I can safely use a 6-pin to 8-pin adapter with my current setup without risking any damage. Is it safe, or could it potentially cause any issues such as overheating or failure?

I wouldn't rely on that 6-pin to provide 216 watts. Typically, a 6-pin connector can only handle about 75 watts. If your power supply only delivers 18A on that rail, you might run into problems if you push it too hard with a GPU. Just be cautious with adding power-hungry components!
Well, keep in mind that the PCI-e socket also gives you an additional 75W, which could theoretically bring it to 150W, but you're still underpowered for most modern GPUs.
It really depends on the GPU's wattage rating. For a GPU around 150W, you should be okay, combining the 75W from the slot and another 75W from the 6-pin. However, stay cautious and use it at your own risk. Do you have two 6-pins available? That would definitely help!
In the long run, it seems like you might need to upgrade to a proper 8-pin connector if your GPU pulls higher wattage. The 6-pin just might not cut it for performance or longevity.
Make sure to check the specific wattage output on that rail. 18A on a 12V rail equates to 216W, so you might have more headroom than you think if the GPU isn't too demanding.
