Tests on the PALIT Omniblack RTX 4090 at various power levels show that running at 100% power offers the least efficient balance between consumption and performance. Operating at 33% power appears to be the safest and most stable option, allowing for continuous 24/7 use over several weeks without risk

I realize this might be useless information, but maybe someone will find it interesting. Personally, I'd love to see similar tests from other GPU hunters — mkeys, power usage, temperatures, and so on
