Testing

Test Setup

To test power supplies, we believe that creating real-world circumstances and conditions are important to consumers who need to relate to what they would use and experience in a computer system setup. Consequently, our methodology is fairly straightforward, as we assemble power-hungry components that will push a unit to its full capacity. We monitor the results at various loads using a digital multimeter for voltage regulation, and an oscilloscope for ripple measurements.

Voltage Regulation

When examining the voltage regulation results we are looking for the voltage output and any fluctuations that might occur. The current ATX specifications allow for the following fluctuations in voltage outputs, and these represent a 3% variance:

  • 3.3V Rail: 3.135V – 3.465V allowable
  • 5V Rail: 4.75V – 5.25V allowable
  • 12V Rail: 11.4V – 12.6V allowable

Below are the voltage regulation results:

When we look at the voltage regulation results, the i700 does well. There was some of movement across the rails, and the +12V is slightly overvolted, but nothing worrisome or out of specification. Keep in mind the i700 is a budget unit, after all, so we’re not surprised to see results like these.

Ripple

When examining the ripple, or noise, the ATX specifications allow for 50 mV peak-to-peak variations for 3.3V and 5V, and 120 mV p-p for the 12V.

We measured the results at just below full load, and the results are as follows:

Ripple results are also fine and within specification. Certainly not the best we’ve seen, but for the price, you get good performance and stability here.

Noise

One last note here relates to the noise produced by the unit. The Yate Loon fan is quiet at low loads, but does ramp up significantly when pushed at higher loads. It will still be far quieter than a typical CPU or GPU fan, so it’s not a real problem, however, if you plan on using the i700 in an HTPC then you may want to reconsider another model or swapping fans if you’re confident enough to do it yourself.
