1st Player NGDP 750W PSU Review

Epilogue

Like the 850W unit, I don’t know the price tag of the NGDP 750W, but I believe that 1st Player will do its best to keep it lower than competing offerings, which are quite many. The PSU achieves a decent overall performance at 115V and high enough at 230V, thanks to its tight load regulation at 12V, the good ripple suppression, the long hold-up time, the low inrush currents, and the high PF readings. The platform’s average efficiency is also high enough, although I would like to see an above 70% efficiency level at super-light loads. Lastly, the fan’s speed profile is relaxed, leading to a silent operation even at higher loads.

The build quality is good, and the ten-year warranty shows Helly’s faith in this platform. I am not familiar with the provided support, though, so feel free to leave a comment about that if you know anything more or even better if you have first-hand experience. Long warranty periods only matter when the support is proper.

 

The areas where Helly should focus on improving are the same as the 850W model. The most important is the 12V rail’s transient response, especially under the challenging ATX v3.1 test scenarios, with up to 200% load levels. The 12V rail drops lower than other units with similar capacity and specs, so the platform needs some tuning and probably more capacitance on the secondary side to fix that. Moreover, the PSU should achieve higher than 70% efficiency with a 2% load, as the ATX spec recommends. Lastly, the sky-high OCP triggering points on the minor rails need fixing since they jeopardize the platform’s reliability.

You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

  • Silent operation
  • Properly set OCP at 12V
  • Within 1% load regulation at 12V and 5V
  • Good ripple suppression
  • Low inrush currents
  • APFC converter performs well (high PF readings)
  • Low vampire power
  • Good soldering quality
  • Long hold-up time
  • Alternative Low Power Mode (ALPM) compatible

Cons:
  • Sky-high OCP triggering points on the minor rails
  • 12V rail’s transient response should be better (normal loads and ATX v3.1)
  • Mediocre transient response at 5V and 3.3V (normal loads)
  • Not tight load regulation at 3.3V (and 5VSB)
  • Below 70% efficiency with a 2% load
