The Corsair SF850 is the objective winner of this comparison, securing more individual specification victories than its competitor. While the ASUS ROG Loki SFX-L 1000W Platinum offers a notable advantage in total power capacity, providing 18% more wattage, the Corsair SF850 maintains a superior position regarding overall value. Its most impactful advantage is a 29% better MSRP, which makes it the more cost-effective choice for users who do not require the higher power ceiling of the alternative.

Users prioritizing budget efficiency should select the Corsair SF850, as it delivers a more favorable price point while matching or exceeding the competition in the majority of measured specifications. Conversely, the ASUS ROG Loki SFX-L 1000W Platinum is the appropriate choice for builders whose specific system requirements demand the extra 18% wattage capacity. Choosing between these two power supplies depends entirely on whether your build necessitates the higher power output or if you prefer the cost savings.
