Happy New Year, readers of mine! Over the seven or so years I've been doing this, I've looked at big and small power supplies alike. Today's unit is on the smaller side of things: the Silverstone ST30SF. This is an 80 Plus Bronze pipsqueak of a unit designed for pipsqueak cases that require an SFX form factor power supply.
Already we find a few interesting features listed on the front that Silverstone hopes will set this unit apart from the crowd. For one, this little guy is somehow rated for full power at fifty degrees, which isn't easy to do in a form factor this size. As if that wasn't enough already, the unit has a semi-fanless mode too!
More marketing is found on the back of the box, as usual, but there's not a lot special about this unit it tells us we didn't already learn from the front of the box. There's a fan curve graph and an efficiency graph, and that's about it. I do find the claim amusing that the fan is supposed to do 18dBA noise minimum. Um... if it's got a fanless mode, you're kind of selling it short there aren't you, Silverstone?
Ah well... how silent can an 80mm fan be, anyway, once it starts spinning?
Elsewhere on the box, we find out that the power supply is black and has dimensions.
We also get a list of connectors with diagrams as to what said connectors look like.
Time to do some unpacking, says I.
In the box we have two manuals, a power supply, a power cord, and a bag full of goodies.
As is typical of Silverstone units, the documentation goes overboard. How many other brands' units do you know of that come with specifications for dielectric strength?
The installation manual, done in multiple languages, leaves nothing up for guesswork. Once again, Silverstone is the absolute master of power supply documentation. And all this data for an SFX unit, too, which is a form factor generally considered an afterthought by most power supply companies.
