"Power Supply does not provide a -12 V supply voltage" warning

[Anthrasite]

I'm looking to replace the PSU in my PC. One that I was considering is the NZXT C1000 (2024) 1000 W 80+ Gold Certified Fully Modular ATX Power Supply, but it gets filtered out by the compatibility filter in PCPartPicker, and when I include it in my current PC build, I get this warning:

 

However, I've been struggling to find information about what exactly this means online. The manual for my Asus ROG Strix X570-E Gaming ATX AM4 Motherboard doesn't have much information on -12V, although it is listed as one of the pins on the ATX power connector:

 

However, the manual for the NZXT C1000 (2024) 1000 W 80+ Gold Certified Fully Modular ATX Power Supply doesn't seem to mention anything about not providing -12V or any potential incompatibilities, and lists a -12V pin in the pinout diagram for the motherboard power connector:

 

The only other thing I've been able to find about this pin that seems relevant is this post, which seems to indicate that this pin is old and isn't really used by any modern hardware:

Is this warning message relevant? Is there some meaningful incompatibility between these two products? I find it very strange that PCPartPicker is filtering out this power supply and providing a warning about potential incompatibility when there doesn't appear to be any information about what this means online.

The -12V rail is optional. Unless you know you have something that uses -12V, you can just ignore it.

PCPP tends to prefer giving too many warnings, rather than too few warnings. They are just so you know some things to check for manually, not them telling you that something isn't compatible. They didn't show the RMx Shift for ages, due to the cables coming out of the side of it, despite lots of cases accomodating it without issue.
