Page 4 - Minor Tests and Conclusion
Power supplies are interesting products -- often, reviews of products in this category are conducted and tested in methods that make it difficult to distinguish one power supply from another. Many aspects have to be taken into consideration -- of which certain criteria consists of efficiency, noise, power ripples, and of course the ability to pull out the rated specifications. Because many cannot afford such equipment to obtain results regarding those aspects, articles covering power supplies often come out with less than adequate and acceptable information. As this is a product report -- not a review -- what we are doing is a close examination of the power supply, and the internal hardware and build. But what we can do for you is do some minor testing with the results we can present to you with, and let other review sites with professional equipment show you the actual test results. We're not going to try to BS you by installing the power supply into the latest gaming rig and try to take readings from that, as this is not even remotely the correct way to test power supply units. We understand that many websites do that as a means of load testing, but the results, even if you use an oscilloscope and multimeter at each output location, is not nearly sufficient, nor does it accurately reflect the performance of the power supply.
Using our power supply tester which exerts minimum load on the power supply, the initial power consumption was 13W. This is quite a bit higher in comparison to our recently reported power supplies, such as the Seasonic S12D 850W at the Cooler Master Silent Pro M 1000W, tested at 9W and 8W, respectively. On the other hand, tests by some reputable sources state that the SilverStone Strider Plus series of power supplies does have good voltage regulation, ripple regulation and excellent efficiency as well. It is definitely enough to live up to its 80+ Plus Silver certification.
The voltages with minimal load are generally accurate and within range. A basic requirement of all good PSUs is to deliver the right voltages through the rails at minimal load, or there could be problems when using it in the first place. The PG (Power Good) measurement is also quite good at 280ms, which is about 20ms less than the average.
In the category of the active power line correction, the SilverStone Strider Plus ST75F-P 750W attained 0.97 power factor (97% PF) sustained. The ideal value is 1.00, so you'll want to be as close to that as possible. It was shifting between 0.97 and 0.98, so in this department, it does a commendable job.
Finally, in the noise category, the SilverStone Strider Plus ST75F-P 750 ran very quietly, from my subjective observations. The Young Lin DFB132512H pushed out a lofty amount of air, while being near silent as perceived with regards to motor and turbulence noise. I can hear the faint hum of the Young Lin fan as it was running, but any component in a standard PC is more likely than not going to be louder than this fan -- except maybe our Editor-in-Chief Jonathan Kwan's computer, haha. On a scale from 0 to 10, where 0 is silent and 10 is the loudest, I would rate the SilverStone Strider Plus ST75F-P 750W to be at 2.0/10 under nominal loads. As the fan spins up, the fan gets increasingly louder, as expected. Personally speaking, the SilverStone Strider Plus ST75F-P 750W is already acoustically sound -- no pun intended -- and should prove to be great for most users in this regard.
Special thanks to Tony over at SilverStone for making this review possible.
The SilverStone Strider Plus ST75F-P 750W power supply is a fully modular package with a large single +12V rail and tight voltage regulation. Being 80 Plus Silver certified, it is without doubt, very efficient; with admirable noise emissions.
