Testing the HALE90 750W PSU

Testing - 4W, 257W & 661W: 

We initially plugged the PSU into an EZ PSU Tester 3 in order to power it on for our "idle" measurements.  As noticed below, the voltage rails were fairly stable with no load, but these aren't necessarily indicative of overall load performance.  According to our Kill-a-Watt, the power draw was 4W.  We thought these results would be interesting to include and compare with other power supplies to see how they manage a non-load situation, and how much power the PSU itself will draw.

As I expected with I was given the opportunity to look at this high-end PSU, no matter what type of load I put on it, the voltage rails stayed clean, and had very little noise.  As you can see by clicking the images above, we captured a small 9.18mv ripple & noise measurement on the 3.3v rail, 18mv on the 5v rail and 36mv on the 12v line.  This is nice and clean power as ATX specifications state 50mv is allowable on the 3.3v and 5.0v rails while 120mv is acceptable on the 12v rails.  Even with a heavy load the NZXT HALE90 PSU stayed well within specifications on the rails.  The 5v line never strayed above 20mV while the 3.3v line stayed in the single digits in terms of ripple.  The +/- 12v lines stayed at less than half of their allowable ripple and noise.  This is a very solid result - even with a 661W load

Instead of taking a ton of pictures of each voltage line under different load, we've graphed the results below.

The voltage is very solid with the NZXT HALE90 750W PSU, and while it tends to be a bit on the high side, the biggest drop in voltage when a load is applied to any of the rails is 0.1v.  On the 3.3v line we see a drop of a mere 0.02v - almost perfect, and on the 5v rail we see a drop of 0.04v - again, incredible.  The +12v rail and -12v rail each drop 0.1v, but they are allowed to fluctuate an incredible 1.2v and still stay within ATX specifications.  Thankfully, they are all rock solid.



The NZXT HALE90 750W PSU is in the middle of the road when it comes to NZXT's new line of PSU as they range from 550W to a full 1000W, and is geared toward consumers with mid-range to high-end PCs with one or two video cards.  Our test system included a hefty Radeon 5870, an AMD 1050T 6-Core Phenom Processor, several hard drives and more and it handled it easily.  It pushes out a lot of watts through the single +12v line and proves to be solid, stable and it runs quite cool.  The hottest internal component reached 42°C when testing in our office with an ambient of 25°C.  It handled everything we threw at it without stumbling, stuttering or any undue concern.

There really isn't much of a downside to this PSU.  It is nice and quiet.  Although it can reach a maximum efficiency of almost 92%, NZXT states that typical load will still stay above 90%.  This is a very nice PSU that certainly deserves a second look.


  • Low electrical noise
  • Rated at 750W Continuous
  • Lots of peripheral and SATA connectors
  • Very stable with a fairly heavy load 
  • 14cm fan is very quiet and cools well
  • Standard size should work in almost every system.
  • Unique modular cables plug into any PSU port


  • Nothing major




NZXT has a rock-solid PSU on their hands with the 750W HALE90 series PSU and it easily earns a "Gold" award here at BCCHardware for performance, quality and low noise.
