SilverStone Strider Titanium ST80F-TI PSU 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 25,000 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

This is what you get when you invest in a Titanium-rated PSU, mainly very high efficiency (>90%) through most of its operational range. As you can see from the graph above, efficiency falls within 90-95% between 70W and 740W.

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).

The temperatures inside the PSU during full load output for a prolonged period are normal. The hottest parts look to be the pair of bridge rectifiers, which went up to 82.5 °C. That's nothing to worry about though, since these specific bridge rectifiers operate properly at up to 150 °C.

    Tier-3 and I think I am being generous. I never thought I would see a Titanium rated unit with such poor performance. I base my decision on the 12V ripple and hold up time.

    I'm not surprised that silverstone opted not to supply an on-off switch. In fact, I can see no reason why this brand keeps getting the high ratings it enjoys.
    I bought one 3 years ago to replace a defective PC Power and cooling PSU.
    the Silverstone 80 Plus gold (Strider S series) lasted just 9 months before it started to produce erratic voltage levels. Sent back for a replacement and that one lasted 15 months. I now have that unit's replacement but it is now a spare to my Corsir RX750.
    At least they honored their warranty...twice.

    they say ripple on 12 volt spec is 120mv so they don't even say themselves that its going to have a ripple under 100 which the writer of this article was expecting. why expect something that the manufacture of this psu didn't say it would do

    Too little Elco and Solid Capacitors on secondary side cause poor ripple and hol up time. Must set new standart, Platinum and Titanium Level should not exceed 50mV on all output rail.
