SilverStone Strider Platinum 750W Power Supply Review

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels measured from SilverStone's ST75F-PT. According to the ATX specification, the limits are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).

Ripple suppression on the +12V rail is excellent. The same goes for the 5VSB rail. At 5V, ripple is quite low, and only the 3.3V rail holds this PSU back. Good thing it's only used lightly in contemporary systems. Of course, the most important rail is +12V, and that one's ripple-proof.

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.

    When you talk about the Teapo capacitors, you mention they have a 3,000-hour lifetime. That's like 125 days? That can't be right, or somehow the lifetime actually has to be applied differently?

    With capacitors, the lifespan is measured at the maximum rated temperature, which in the case of these capacitors is 105 degrees Celsius. But as the temperature that the capacitors is exposed to drops, the lifetime increases, so for example, the lifespan of those capacitors at say 50 degrees might well be 75,000 hours

    I am not very familiar with PSU standards. What exactly is the second EPS connector used for? Is it only some X99 boards? Or are also some Z170 boards affected? Planned to get a Asus Z170 Pro Gaming but that one seems to be fine, if I am correct.

    Also I planned to potentially use 2 GTX 980 Phantom Cards - but if I am correct the Power supply wouldn't be able to support 2 cards, as one of these already requires 1X 8Pin and 1X 6Pin Connection.

    Can anyone tell me if I am correct, and give me a suggestion of an alternative, equally priced and silent PSU if possible?
