Value and Conclusion
- The V750 retails for $139.99 from Cooler Master's online shop
- Delivered full power at 47 °C
- Good build quality
- Excellent transient response at +12V
- Low ripple on all the rails (without using in-cable caps)
- Long hold-up time
- Sufficient number of connectors (including 2x EPS & 4x PCIe)
- Selectable semi-passive operation
- 10-year warranty
- High price (because of tariffs) and limited availability in the US
- The PSU doesn't use an MOV and an NTC thermistor relay combo, for surge and inrush current protection (measured inrush currents were still low)
- Overall performance is high enough but not up to the competition's levels (Corsair, EVGA, and Seasonic)
- Transient response at 3.3V should be better
- Not all that quiet (Cybenetics LAMBDA-S++)
- Small distance between peripheral connectors
The main problem with the V750 is its restricted availability in the US due to Trump's tariffs, along with its high price, neither of which is specific to this product since more and more brands are forced to increase the prices of their products in the US, and there are cases where products have been removed from the US market entirely until production has moved out of China. It is not a secret anymore that most manufacturers have started building production lines in other countries, of which the most promising country so far is Vietnam.
The V750 is of good build quality and has excellent transient response at +12V, along with a pretty long hold-up time and low ripple on all rails. There is also a selectable semi-passive operation, which makes this PSU compatible with all cases, and a ten-year warranty. But the good features stop there. Overall performance isn't up to the competition's levels (Corsair RM750x and RM750, Seasonic Focus Plus Gold 750 W, etc.), and at 34-36.5 dB[A] for the two samples I tested so far with 115 V input and 33.76 dB[A] with 230 V input, overall noise output is quite high. Finally, there is no MOV in the transient filter, and although CM's PSU engineer informed me that there is no need for one, I am of a different opinion. As for the lack of the NTC thermistor and corresponding relay, I didn't measure high inrush currents, and I conducted that test several times. Still, I would prefer to see those two components included.
It would be nice if my sample had AWG16 gauges on the PCIe connectors since it would result in tighter load regulation. According to CM, mass-produced units, those on store shelves, will come with AWG16 gauges on the PCIe connectors. My sample was from an earlier production batch, so it used the standard cable kit.
The V750 is suitable for users who want the best-possible +12V rail performance, but don't mind its higher noise output compared to other offerings of similar wattage. Also keep in mind that the +12V rail is the most important rail of all. However, with less money, you can find much quieter options with notably higher overall performance.
