Conclusion:

 

Price Per the Watt:

Power Supply NZXT HALE90 750W at $144.99 = $0.19/Watt (06-2011)

 

The NZXT HALE90 750W power supply produced good quality DC rails with very little AC ripple/noise. The efficiency wasn't quite up the level required by the 80 Plus Gold standard following the OCC power supply testing methodology, but most power supplies seem to fall a little short in this department. (I can't exactly replicate the rail loading levels used during 80 Plus testing so it's probably the methodology rather than the power supplies). The NZXT HALE90 750W power supply did reach 91% efficiency (230VAC) which is still up there with other power supplies in its class claiming 80 Plus Gold efficiency.

The NZXT HALE90 750W power supply got a little warm during testing thanks to a cooling fan that remained at or around 700 RPM at all times. I've come across this same behaviour very recently and on investigation the Sentey Golden Steel Power 850W and the NZXT HALE90 750W are based on the same Super Flower design. The introduction of a little warm air into the NZXT HALE90 750W power supply, like the Sentey, caused the cooling fan speed to ramp up to 1400 RPM.

The NZXT HALE90 750W power supply produced good quality DC across all the rails with high efficiency. The build quality is good and I'm sure the white finish won't be to everyone's taste, but it's certainly different and I have no hesitation in awarding it a OCC Gold award.

 

Pros:

  • Good DC quality
  • 80 Plus Gold
  • Flat modular cables
  • 5 year warranty
  • Plenty of connectors
  • Quiet

 

Cons:

  • High temperature/low fan speeds at full load (out of case)
