The Corsair SF1000 (2024) is the objective winner of this comparison, securing victories in five out of seven measured specifications. Its most impactful advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the alternative. This feature ensures superior compatibility with modern high-performance hardware that requires this specific power delivery standard, making the unit a more future-proof choice for users building systems with the latest graphics cards.

The Seasonic Focus GX-650 is the preferred option for budget-conscious builders, as it offers a 55% advantage in MSRP. Users should select the Corsair SF1000 (2024) if they prioritize the advanced connectivity required for modern, high-wattage components.
