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 higher than that of the NZXT HALE82 N 650W PSU, we can test it to the maximum.
The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.
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 with a total drop of .19V from start to finish. The 5V rail also stayed within 2% voltage regulation and displayed a total drop of .11V. Moving towards the 3.3V rail, we see that regulation was again within 2% with a total voltage drop of .09V.
DC output quality was good from start to finish. Starting out, we were able to see a ripple on the scope during Test 1 where we measured noise at a low 21mV 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 28mV. Under Test 4, we saw that the noise on the 12V rail had crept up to 46mV at full load.
The NZXT HALE82 N 650W PSU 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 N 650W power supply had no trouble achieving this while on our test bench.
NZXT is doing a great job capturing their share of the power supply market. Their entrance was marked by the HALE90 series and it made a very strong impression on the enthusiast community. Now that NZXT has a solid reputation for their power supplies, they are making a push to grab even more of the market. The HALE82 N is a perfect unit for capturing the low end and entry level computing market. It may not have all the bells and whistles, but it solid performance and that is what matters most.
The HALE82 N surprised us for an entry level power supply with its excellent voltage regulation. Years ago this level of performance was only seen in high-end enthusiast grade power supplies, but now we are seeing it in the lower end power supplies. DC output quality was rather good, especially considering the CapXon capacitors on the secondary side. Most units that we have seen with these capacitors tend to have sub-optimal DC output quality, but NZXT has managed to pull it off. The HALE82 N is 80Plus Bronze rated for efficiency and it doesn't disappoint on this front either.
As more and more of these lower end power supplies enter the market, it becomes much harder to justify spending your money on a higher end power supply. The differences are becoming negligible to the point where the only significant differences you find are in efficiency, modular connectivity, silence, etc. This is great for those looking for an entry level power supply and why we think that the NZXT HALE82 N 650W is such a great power supply. You simply can't beat the performance when you're on a tight budget.
