Corsair CX750 750W ATX Power Supply CP-9020015 or Antec TruePower Quattro 850W Semi-Modular 80+ Bronze ATX Desktop PSU TPQ-850 which is better
Both the Corsair CX750 750W and the Antec TruePower Quattro 850W are reputable power supply units (PSUs) from well-known manufacturers. However, the “better” choice depends on your specific needs and requirements. Here are some factors to consider:

1. Power Output: The Antec TruePower Quattro offers a higher wattage at 850W compared to the Corsair CX750’s 750W. If you have a power-hungry system with high-end components or plan to upgrade in the future, the Antec PSU might provide more headroom for your power needs.

2. Efficiency: The 80+ Bronze certification indicates that both PSUs meet a certain level of energy efficiency. However, the Corsair CX750 has a slightly higher efficiency rating, as it is listed as 80+ Bronze certified, while the efficiency rating of the Antec TruePower Quattro is not specified. If energy efficiency is a priority for you, the Corsair CX750 may be a better choice.

3. Modularity: The Antec TruePower Quattro is semi-modular, which means some of the cables are detachable, allowing for easier cable management. On the other hand, the Corsair CX750 is not explicitly mentioned as modular or semi-modular, so it’s likely non-modular, meaning all the cables are permanently attached. If you value easier cable management and a cleaner build, the semi-modular design of the Antec PSU may be preferable.

4. Brand Reputation and Customer Support: Both Corsair and Antec are well-established and respected brands in the PC hardware industry. They offer reliable products with good customer support. You may want to consider factors like warranty length and customer reviews to assess the overall reputation of each brand.

Ultimately, the choice between these two PSUs depends on your specific requirements, such as your system’s power demands, desired efficiency, modularity preference, and budget. Consider these factors along with any other specific needs you have, and choose the PSU that best suits your setup.
