Silverstone Strider 850w ST85F PSU

Looking Inside

Its fair to say that I’ve opened up quite a few Silverstone Strider units over the past year, and barring a few upgraded capacitors and transformers not much has ever changed. Will this be the case for the ST85F, or does it have something new up its sleve for me to talk about?

In comparision with the ST75F internals (seen here) the ST85F does look somewhat less crowded. One of the most noticable changes is the downgrade from two +12v transformers to just one – most likely owing to the reduction from four +12v rails down to two. We can also see that the main capacitor has been downsized and several of the smaller wire-wound coils are no longer present. This minimalistic approach may sound worrying, but as we’ve seen many times in the past, it’s not always the bulkiest power supplies that are the best performers.
Silverstone ST85F Fan
The Strider makes use of a standard 135mm brushless fan manufactured by Young Lin Tech. I was unable to find any definite figures for this fan, but as the Silverstone specs suggest, the fan is rated at 22dbA when running at top speed.
