This feature ensures superior compatibility with modern high-end graphics cards that require this specific power delivery standard, making it the more versatile choice for current hardware configurations.

Users prioritizing modern connectivity and higher power capacity should select the Corsair RM1000x (2024) for their builds. Conversely, those who prioritize power conversion efficiency should opt for the Seasonic Prime TX-850, which holds a 50% advantage in that category.
