I'm building my PC today and trying to figure out if my power supply unit (PSU) is compatible with my graphics card (GPU). I've noticed that my GPU has a 3x8 pin power connector, but my PSU only came with 2 PCIe cables that are 6+2 splitters. My GPU manual warns against using both ends of a splitter on a single power connection. Is it essential for me to order another PCIe cable or can I work with what I've got? Sorry if this seems like a silly question!

You can use one of your PCIe cables as is and the other with a pigtail. Just be aware that one pigtail will be left unused. It should work fine, but double-check to make sure it doesn't violate your GPU's power requirements.
Is that really safe? My GPU's manual explicitly says that using both ends of a splitter on one power connector could potentially cause damage.
