Efficiency

Using the efficiency results from the previous page, we plotted a chart showing efficiency of the HALE82 V2 700 W at low loads and at loads equal to 20%-110% of the PSU's maximum-rated load.



Efficiency at low loads is above the average of the corresponding category, so it is good enough. The NZXT HALE 82 V2 takes the last spot at normal load. Overall efficiency at normal loads is fine for a Bronze unit, but not high enough to eclipse the second to last unit, the Integra R2. To speak frank, we didn't expect better results given its outdated design.

Efficiency at Low Loads

We measured the efficiency of the HALE82 V2 700 W at loads much lower than 20% of its maximum rated load (the lowest load the 80 Plus Standard measures) in the next tests. The loads that we dialed were 40 W, 60 W, 80 W, and 100 W (for PSUs with a capacity over 500 W). This is important for settings where the PC is in idle mode with Power Saving turned on.


At low loads, efficiency is high enough since the 80% mark is eclipsed in three out of the four tests. The unit even managed to stay away from the 70%-75% region with 40 W load, which is noteworthy for a Bronze PSU with 700 W capacity.

5VSB Efficiency

The ATX spec states that 5VSB standby supply efficiency should be as high as possible and recommends 50% or higher efficiency with 100 mA of load, 60% or higher with 250 mA of load, and 70% or higher with 1 A or more of load.

We will take four measurements: one at 100, 250, and 1000 mA, each, and one with the full load the 5VSB rail can handle.


The 5VSB rail starts with good efficiency readings but fails to keep its performance up in the last two tests. Also, as you can see from the table above, efficiency drops during the last test, so the 2.5 A on this rail are very close to the maximum amperage the rail can handle.

Power Consumption in Idle & Standby

In the table below, you will find the power consumption and the voltage values of all rails (except -12V) when the PSU is in idle mode (powered on but without any load on its rails) and the power consumption when the PSU is in standby mode (without any load at 5VSB).


This PSU only needs 0.12 W in standby mode, making its compliance with ErP Lot 6 2013 requirements a breeze.

Delta Temperature & Output Noise

A chart that shows the delta difference between input and output temperature and the output noise follows. We measure the fan's noise from 1 meter away, inside a small custom-made anechoic chamber whose internals are completely covered in specialized soundproofing material (Be Quiet! Noise Absorber Kit). The background noise inside the anechoic chamber was below 30 dBA during testing and the results were obtained with the PSU operating at 38°C-46°C ambient.



The following graph illustrates the fan's output noise throughout the entire operating range of the PSU. The same conditions of the above graph apply to our measurements, but the ambient in this case was between 28°C and 30°C.



Hand's down one of the noisiest PSU's we have ever tested, noise haters better avoid this PSU at any cost.
