Our Testing Method and Test Results
Our load tests utilize a couple of FAST ATE active load testers, and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe, and a power consumption meter. You can read more about our standard testing approach here.
The tests performed are based around six conceivable setups that are out there, and progressively load down the PSU up to the power supply's limits, or 1000W; whichever comes first. Since our test equipment's limits are lower than that of the SilverStone ST75F-GS V2 750W power supply, we can test it to its maximum.
The above tests represent typical loads that we have measured from various systems, and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different, and actual loads can vary greatly, even with similar hardware.
Let's start by taking a look at the voltages, to see how well this unit did during testing. Starting with the 12V rail, we see 2% regulation from start to finish, with a total drop of .22V. The 5V rail managed to stay within 2% of specification, with a total drop of .10V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 2% of specification, with a total voltage drop of .09V.
DC Output quality for the SilverStone ST75F-GS V2 was good, and well within specifications. During Test One, we saw 18mV of noise on our scope at 22% load. When we increased the loads in Test Two, the ripple climbed to 26 mV at around 43% load. Increasing loads even further showed that the noise on the 12V rail climbed to 46mV at 750W.
The SilverStone ST75F-GS V2 is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87% / 90% / 87% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the SilverStone ST75F-GS V2 performed exactly as would be expected to reach these levels of efficiency.
