NZXT HALE82 750-watt Power Supply Review

Test Results


Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.


The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are greater than that of the NZXT HALE82 750W, we can test it to the maximum.






Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rail, we see 2% regulation from start to finish with a total drop of .17V throughout all the tests. The 5V rail fared just as well with 2% voltage regulation and a total drop of .12V. Moving towards the 3.3V rail, we see that regulation stays at 2% with a total voltage drop of .09V.


DC output quality was good from start to finish. Starting out, we were clearly able to see a ripple on the scope during Test 1 where we measured noise at a low 18mV peak to peak. This steadily increased as the loads also increased. By the time we had reached around 50% load, the unit ripple had crept up to 32mV. Under full load, we saw that the noise on the 12V rail had crept up to 38mV.


The NZXT HALE82 750W is rated for 80Plus Bronze efficiency. This means that the power supply must perform at 82%/85%/82% efficiency at 20%/50%/100% loads respectively. As you can see, the HALE82 750W managed to score a pass while on our test bench. At no time was the unit close to failing for efficiency.



Final Thoughts


The NZXT HALE82 750W performs just as well as we expected it to and almost identically to what we saw from the HALE82 850W unit. Voltage regulation was great, DC output quality was good, and efficiency was just what you would expect from an 80Plus Bronze rated unit.


The same three day replacement warranty also applies to this unit. Unfortunately the price point is what sets this unit apart from the 850-watt unit. At a price of $115-$120, it puts it square in the middle of the price range for 750-watt units and right at the same price as units with better features and higher efficiency.
