| Conclusions |
 ASUS U-75HA uses a different project from ASUS U-65GA, achieving a better performance. From the three power supplies offered by ASUS, this one is the best. For what its intended target audience – mainstream users – this unit provides a satisfactory performance, with efficiency between 83% and 84% if you pull between 150 W and 450 W from it, dropping to 82% at 600 W and 79.2% at 750 W. Voltage regulation was one of the highlights from ASUS U-75HA, with all voltages within 3% from their nominal values if you pull up to 600 W from it, i.e. closer to their nominal values than required, as the ATX specification allows voltages to be up to 5% from their nominal values. This includes -12 V, an output that usually doesn’t like to stay so close to its nominal value. During our 750 W test the +3.3 V output (and only this one) went outside this tighter range, but was still inside the maximum allowed (5%). Noise and ripple was low all the times. And plus it has its protections working just fine. Of course coming from a brand like ASUS, we’d expected a product with a better performance – and probably that is why ASUS doesn’t offer this product in the United States – but they are clearly targeting more mainstream users on other markets. There are many 750 W power supplies on the market better than this one, but if you are on budget it may be an option. |
