ASUS ROG STRIX 1000W Gold Aura White Edition PSU Review

Efficiency and Voltage Ripple

Voltage Ripple and Efficiency Testing

When reviewing new power supplies at OC3D, we use our dedicated SunMoon PSU Tester, one of the most expensive (if not the most expensive) tools in the company’s arsenal. Here we can see exactly how well a unit functions. We look at both a PSU’s efficiency and power stability. To do this, we utilise bespoke PSU testing equipment to give us an in-depth look at each power supply’s performance. This kind of data collection is not possible when using a PSU with standard PC components.

ROG STRIX Aura White Edition 1000W Efficiency

Efficiency-wise, ASUS’ ROG STRIX 1000W Gold Aura White Edition PSU lands exactly where we expect it. This is an 80+ Gold rated power supply with 80+ Gold levels of efficiency. So far, so standard.

Voltage Ripple

Voltage ripple is often underlooked by consumers, being best described as the stability of specific voltages that the PSU delivers. A PSU with bad ripple will see voltages vary a lot more. In extreme cases, this can can damage components or shorten their lifespans. Voltage ripple stability is one of the many reasons why you should buy a high-quality power supply. That means buying from a reputable brand and avoiding anything that isn’t 80+ certified.

An important thing to note here is that none of the PSUs in this graph are “bad”. Even bottom of the chart units like the original Corsair RM1000 (2014) bring usable within your system without any issues. We used this specific power supply within one of our main workstations for years, and we had no trouble with it. As we said before, only extreme levels of voltage ripple is dangerous.

For ASUS’ new ROG Strix Aura power supply, voltage ripple is at very reasonable levels. At all times, ripple is below 25mV. That’s the level of voltage ripple that we expect to see from a modern PSU, but it is far from the best we have seen.
