I recently purchased an ASRock PRO-650B power supply and I'm a bit confused. The specifications claimed it would support PCIe with a "6+2 Pin x1" connector. I was under the impression that this would at least allow my GPU, which requires two 8-pin connections, to work properly with either two separate cables or a daisy-chain. However, upon receiving the unit, it only came with a single PCIe 6+2 pin connector, and there was no second connector or cable at all. My GPU is an RX 6700 XT (XFX QICK), which clearly needs two 8-pin power connections. I'm trying to figure out a few things: Is it standard for this PSU to only provide one PCIe connector? Is the specification poorly written? Also, am I right in thinking that using a 1x8-pin to 2x8-pin splitter for my 6700 XT would be risky? I've read that a splitter would only divide a single power source and not actually deliver the correct power needed for the GPU. At this point, I'm starting to think this power supply isn't suitable for my RX 6700 XT, despite being rated at 650W.

You're spot on. The ASRock PRO-650B indeed comes with just one 8-pin connector by design. I wouldn't recommend using a splitter; they can be risky since they'd split a single power source, which doesn't give enough power for a demanding GPU like the 6700 XT. Definitely consider getting a different power supply that meets your needs!
That PSU is pretty clear about what it's offering, and it sounds like you've got exactly what was advertised. If it only comes with one PCIe connector, then returning it for a model that has at least two connectors is a good idea if you need to power a GPU like yours.
Thanks for the input! I’ll get it returned.
First off, you’re not mistaken; the specification shows it only has one PCIe connector. As for using a splitter, that's a no-go. Splitting the power could lead to overheating issues if the gauge of the wiring isn't up to the challenge of two 8-pin connections. It's best to get a new PSU that fits your graphics card's power requirements.
Thanks for clarifying that! I’ll avoid the splitter for sure.
I appreciate your help! I’ll look for another PSU.
