SilverStone Strider Titanium ST80F-TI PSU Review

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the ST80F-TI's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).

The ripple suppression we measured is bad. In a flagship offering like this one, we expect much better results. Enhance isn't known for its performance in this discipline, but here it doesn't even seem to try improving.

During our full load test, the +12V rail registers over 100mV ripple, while strangely the minor rails remain at fairly safe levels. However, the 5V rail fails in the 80% and 90% load tests. And, in general, ripple on all of the minor rails increases notably during those load levels. This is something that Enhance should investigate and fix. It is unacceptable to see a Titanium-class PSU failing to keep its ripple levels within the ATX spec's very loose ranges.

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
