With an MSRP close to $100, the TX750M is a very good choice, but I couldn't find it priced anywhere at close to its MSRP while reviewing the unit. As the pros list shows, this product has many positive aspects. That said, some of its cons are significant, with uncompetitive overall performance being at top of the list.
The TX750M needs more capacitance on the secondary side for a better transient response, a crucial facet of every modern PSU. Moreover, ripple at +12 V should be below 30 mV to be competitive. While 39.3 mV ripple at +12 V under full load and at 47 °C is still pretty good, the EVGA SuperNOVA 750 G6 is at 11.8 mV and Corsair RM750x at 8.9 mV under the same conditions, which should also give you a good idea of how tough the competition is in this category.
If you need a PSU with high build quality and don't care about the semi-modular cable design, or top performance in all areas, the TX750M fits the bill. It uses better parts than the RM750 and is sold at about the same price. However, the RM750 provides notably higher overall performance, and all of its cables are fully modular. On top of that, the RM750 is quieter than the TX750M, which doesn't mean the TX750M is noisy, though.
