The Seasonic Prime TX-1300 ATX 3.1 is the objective winner of this comparison, securing victory in five out of seven evaluated specifications. Its most significant advantage over the alternative is the inclusion of the 12VHPWR connector, which represents a 100% improvement in connectivity capability. While the Seasonic Focus GX-750 remains a viable option, it only leads in one category, specifically offering a 74% better MSRP compared to the higher-tier model.

Users prioritizing modern hardware compatibility and high-end power delivery should select the Seasonic Prime TX-1300 ATX 3.1 for its superior connector support. Conversely, the Seasonic Focus GX-750 is the logical choice for budget-conscious builders who do not require the advanced connectivity features of the more expensive unit. Choosing between these two power supplies depends entirely on whether your build necessitates the latest connector standards or if you prefer to prioritize a more favorable initial purchase price.
