The ASUS ROG THOR 1200W Platinum III is the objective winner of this comparison, securing more individual specification victories than its counterpart. While both units share several identical features, the most impactful advantage for the THOR 1200W Platinum III is its SATA connector count, which provides a 33% increase over the alternative. This hardware superiority makes it the more robust option for systems requiring extensive peripheral connectivity and higher power overhead.

Users prioritizing budget efficiency should select the ASUS ROG Loki SFX-L 1000W Platinum, as it offers a 35% advantage in MSRP compared to the larger unit. Conversely, those building high-capacity workstations or systems with numerous storage drives should choose the THOR 1200W Platinum III to leverage its superior SATA connectivity. The choice between these two power supplies ultimately depends on whether your build requires maximum peripheral support or a more cost-effective power solution.
