Dev Hardware reviews 2theMax GPX750 PSU and concludes that the PSU has nice power of 750W, has 4 separate 12v rails, is modular PSU, serious cooling ability, well constructed and will meet most power needs. However, it’s a little noisy with big fan and power fluctuations may deter picky users. Overall, “based on the above, as well as my testing, I give this PSU a rating of 8 out of 10, and Dev Hardware’s Recommended Product Award. This PSU delivers strong power and stays extremely cool. Had the power stuck a little closer to spec, and the fan been a little quieter, it definitely would have earned a higher rating.”
