The DeepCool PX850G is the objective winner of this comparison, securing victories in six out of seven evaluated specifications. Its most significant advantage over the competition is its warranty, which provides 233% better coverage duration. This superior reliability profile establishes the unit as the more robust option for long-term system stability. While the EVGA 500 BQ manages a win in a single category, it cannot match the comprehensive technical superiority demonstrated by the DeepCool PX850G across the board.

Users prioritizing long-term hardware protection and peace of mind should select the DeepCool PX850G for its significantly extended warranty. Conversely, the EVGA 500 BQ is the appropriate choice for budget-conscious builders who prioritize a lower MSRP, which is 64% better than the alternative. By weighing the importance of extended manufacturer support against initial acquisition costs, buyers can determine which of these two power supply units best aligns with their specific build requirements.
