SilverStone Strider Platinum 750W Power Supply Review

Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1500 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.

Load Regulation Charts

Efficiency Chart

As you can see from the graph above, the ST75F-PT has a very wide operating range with over 90 percent efficiency. This is why you pay a premium for 80 PLUS Platinum-rated power supplies.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

Temperatures inside the PSU approached 55 °C during our full load test, and some parts got even hotter, measuring 70 to 80 °C. Compact dimensions and a slow-spinning 120mm fan doesn't facilitate better cooling under such difficult conditions.

    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?
