SilverStone Strider Titanium ST80F-TI PSU Review

Performance, Performance Per Dollar, Noise and Efficiency Ratings

Performance Rating

The following graph shows the PSU's total performance rating, comparing it to other units we have tested. To be more specific, the ST80F-TI is shown as 100 percent, and every other unit's performance is shown relative to it.

Because of its ripple issues, especially at +12V, the ST80-FI cannot claim a higher place in this chart. If Enhance could pull ripple down closer to 40mV on the +12V rail, it would definitely land a more desirable position, surpassing many similar-capacity offerings.

Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the unit's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.  

The combination of a high price and a mediocre relative performance score sets the ST80F-TI's ceiling here.

Noise Rating

The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 28 °C and 30 °C (82 °F to 86 °F).

This is a quiet unit if you keep its operating temperature below 40 °C. More than likely, that'll be the case in side of a chassis with decent airflow.

Efficiency Rating

The following graph shows the average efficiency of the PSU through its operating range, with an ambient temperature between 28 °C and 30 °C.

Overall efficiency is pretty high, though it's still significantly behind EVGA's 850 T2 based on one of the best Titanium-class platforms available. EVGA's biggest issue is that its offering costs so much.

    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.
