Some users may believe that a 2017 model might be outdated, but I find its performance still excellent for my requirements. I had worries about the cooling system, as water cooling is effective but complex to install. However, the CX750M’s semi-modular design simplified the process more than expected.
Overall, the CX750M’s 80 PLUS Bronze certification provides assurance for my decision, ensuring both reliability and affordability. While it doesn’t offer the highest efficiency, the energy savings over time make it a worthwhile investment for my system.
