Silverstone, the winner in many of our previous efficiency tests, seems to be resting on its laurels. This time around, it lands in last place. Let’s look at the numbers:
Under full load, the Strider’s efficiency is 82.2 percent. At half-load it’s a bit better—Silverstone ends up in the midfield with 86.5 percent. The SST-ST70F truly looks good only at low load, where the power supply outperforms its competitors with 86.7 percent.
This trend continues as the load falls. In our low-power comparison at 35 watts, the Silverstone power supply performs best in the test field with more than 78 percent. But if you’re a low-power user, you’re probably not in the market for a 700 watt power supply, so it’s a bit of a catch 22.
The result for standby is average. At zero load the Strider consumes 1.17 watts; at a load of 2.5 watts it needs 4.57 watts.
The power supply from Silverstone combines high performance with good cable management, long cables, and many plugs.
