Pros, Cons And Final Verdict
This Titanium-rated platform's most glaring flaw is ripple suppression. Unfortunately, Enhance Electronics cannot match the performance of competing OEMs. And given our experience with Super Flower's amazing Leadex Titanium platform, it's easy to feel disappointment upon measuring more than 100mV of ripple at +12V. This is a great shame for the ST80F-TI since its load regulation is good, it features quiet operation, and its efficiency is high overall (particularly under light loads). More than likely, the effort to minimize the PCB's dimensions hurt ripple performance.
In our opinion, it's time for SilverStone to revisit its priorities. We like that the company offers compact PSUs. However, in this category, performance is what matters the most. If you have to sacrifice performance for a smaller footprint then you're doing it wrong. Ripple and load regulation are two of the most important performance factors, so you have to keep both in mind during the design process. In no case should you allow for such high ripple levels, especially on the +12V rail.
The good aspects of the ST80F-TI are its compact dimensions, modular cabling design, low noise output, long-lasting FDB fan, and high-quality components (like Japanese electrolytic caps).
On the other hand, besides terrible ripple performance, other notable downsides include a very low hold-up time, high inrush current, the lack of a power switch, and that $170 price. Although it's normal compared to other Titanium-class PSUs, SilverStone should lower it in light of the issues we found. In addition, although a five-year warranty is long enough, competing vendors support their hardware with even better protection. For example, EVGA and Corsair offer 10-year warranties.
If SilverStone manages to persuade Enhance to look into this design and vastly improve its ripple performance, the ST80F-TI should stand a better chance against Super Flower's top-notch Titanium platform, which EVGA uses in the SuperNOVA T2 family. That's no easy task, though. It'll likely require a highly modified or entirely new implementation. With the release of Seasonic's new Titanium units (Prime series), the competition in this category will be even tougher. Perhaps it's time for SilverStone to start looking at other OEMs altogether.
