SilverStone Strider Titanium ST60F-TI PSU Review

SilverStone released its first Titanium PSU series, which is made by Enhance Electronics. The smallest Strider Titanium unit will be under our scope today. Besides high efficiency it also offers compact dimensions and a fully modular cable design.

Not only is the hold-up time lower than 17ms, but the power-good signal also lasts much longer. When it drops, the rails are already out of spec. This is a major downside for a PSU, especially a high-end one.

Inrush Current

The inrush current is pretty high, mainly with 115VAC input.

Load Regulation And Efficiency Measurements

The first set of tests reveals the stability of the voltage rails and the PSU's efficiency. The applied load equals (approximately) 10 to 110 percent of the maximum load the supply can handle, in increments of 10 percentage points.

We conducted two additional tests. During the first, we stressed the two minor rails (5V and 3.3V) with a high load, while the load at +12V was only 0.10A. This test reveals whether a PSU is Haswell-ready or not. In the second test, we determined the maximum load the +12V rail could handle with minimal load on the minor rails.

Load regulation at +12V is super tight, especially for a Titanium-rated PSU. Usually, compromises have to be made to enable low energy losses. Regulation is good on the 5V and 5VSB rails as well, while at 3.3V the deviation is within 2.5 percent.

But let's skip to the important part: this PSU's efficiency levels. Under 10 percent load, the 90 percent efficiency mark is passed; the same goes for our 20 percent load test. With 50 percent load, we should measure at least 94 percent efficiency. Instead we get a much lower reading of 92.71 percent, though. Finally, under full load, the PSU approaches 90 percent so we're giving it a pass. Obviously the low reading at 50 percent load has to do with high ambient temperatures compared to the conditions used by the 80 PLUS organization. No doubt this is a highly efficient PSU, though we've seen Titanium-rated units scoring better.

The fan profile becomes aggressive once the PSU's operating temperature exceeds 35 °C. So, only during the first two tests noise is kept at low levels. Under 40 percent load and up, the acoustics worsen. We also noticed an increased fan bearing noise during the 40 and 60 percent tests. Finally, the PF readings are pretty high, even during the first test where the load level is only 60W.
