I'm considering using a SATA to PCIe adapter to power a device that draws around 27 watts. Do you think this will work without any issues, or is there a risk of the adapter melting?

For 27 watts, you should be totally fine. If you're still worried, look into using Molex to PCIe or dual SATA to single PCIe adapters—they're often better for the job.
I really wouldn't recommend using that kind of adapter. The power limit for SATA is much lower than PCIe, so even if you're only drawing half the maximum, it's still risky.
This could potentially be a fire hazard. You don’t want to take any chances with power connections, so be careful!
Can you explain why you think so?
It's a bit odd to see a device using a PCIe cable at just 27 watts. What are you trying to power with that?
Not something I want to discuss until I'm ready to share it!
While SATA cables can handle up to 54 watts theoretically, it all boils down to the PSU's capability to deliver that much power. Just because the cable is rated for higher doesn't mean your PSU will provide it. I'm curious about what exactly you're adapting, though.
I'd rather keep that a secret for now!
Yeah, but I'm only going to use about 13 watts.
