The Corsair RM1200x SHIFT is the objective winner of this comparison, securing more individual specification victories than its competitor. The most impactful advantage offered by the Corsair RM1200x SHIFT is its total power capacity, which provides 20% more wattage than the ASUS ROG STRIX 1000G. While both units share several identical specifications, the higher power ceiling of the Corsair model establishes it as the superior option for systems requiring greater electrical overhead.

Users should choose the Corsair RM1200x SHIFT if their build demands maximum power delivery for high-performance components. Conversely, the ASUS ROG STRIX 1000G is the better choice for budget-conscious builders, as it holds a 12% advantage in MSRP. Selecting between these two power supplies depends entirely on whether your priority is the increased wattage capacity of the Corsair unit or the improved cost efficiency provided by the ASUS model.
