Introduction, Specifications, Availability and Pricing
Recently we took a look at the new NZXT HALE82 850W power supply and we were very pleased with what it had to offer.
We decided we wanted to take another look at the see if the entire series represented just as much value as the 850-watt PSU model offered.
Today we are taking a look at the 750W HALE82 power supply and are running it through the ringer on our bench.
Specifications, Availability and Pricing
NZXT rates the HALE82 750W for 25A on both the 3.3V and 5V rails with a combined total output of 150W. This is certainly a welcome step up from before. 62A of power is served up on the single 12V rail which should provide plenty of power for the four PCI-E connectors available with the unit.
NZXT expanded the features just a little bit on the HALE82 power supplies. This time around we get a full range of protections with the addition of over temperature protection. Usually when this is added they also rate the unit for 100% continuous output at 50C but oddly enough, we couldn't find any documentation that the unit had the rating. The power supply still sports both native and modular cabling.
NZXT has the HALE82 power supplies readily available through all of your normal online merchants. Once again, the cheapest we were able to find the unit online at the Directon for a total of $114.99 with free shipping.
NZXT gladly backs the HALE82 with a 5-year warranty. If you keep your receipt or register the unit online, NZXT promises to have your unit replaced in 3 days should it die AND they will pay for shipping both ways.
The packaging is almost identical to the HALE90 series with a small window to catch a glimpse of what is inside and some of the major features highlighted. Note the sticker on the front that also lets you know about their new warranty. You have to <3 the name, Less Than Three.
The back has a good list of cables and specifications.
One side has a few charts depicting the efficiency and noise of the unit.
The other is simply blank.
The top is not quite as simplistic as the last picture, but very close as it only contains the NZXT logo.
Checking out the bottom you will find a list of features in multiple languages.
Inside the Box
Here we find out things are packed inside the box. The unit is protected by plenty of foam so that it doesn't receive any damage during shipping.
On top is the I/O specification label and serial number.
On one side we find a simplistic side with just the NZXT logo stamped into the metal.
The other side is as plain as can be as it doesn't even have the logo stamped into it.
Moving to the back of the HALE82, we find the standard honeycomb mesh with on/off rocker switch and AC input.
Here we have the modular connections on the front as well as the native cables exiting the unit. NZXT uses both a grommet and a zip tie to protect the native cables exiting the power supply.
The bottom of the unit houses the white fan with wire grill that cools the HALE82 power supply. The white fan gives a nice look to the unit if you are seeking something with high contrast.
All of the modular cables included are of the flat ribbon type and are not sleeved.
Also included are the user manual, AC power cord and mounting screws.
Cabling Arrangement and A Look Inside[Heading]Cabling Arrangement
NZXT makes sure that you have plenty of cables with the HALE82 series. Dual ATX4+4/EPS12V and four PCI-E connectors ensure that you'll be able to use all the juice it offers while the five peripheral cables make sure that you'll be able to power all of your drives and accessories. As before, there are two very nice things to note here is that there are both short and long SATA cables as well as no floppy connectors.
NZXT keeps the rail distribution sweet and simple with a single 12V rail.
A Look Inside
Opening things up, we find ample cooling inside a very busy power supply.
A pair of Japanese made Nippon Chemi-Con caps adorns the primary side of the HALE82 750W power supply.
More Nippon Chemi-Con can be found on the secondary side of the PSU.

Test Results and Final Thoughts
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.
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.
