Silverstone ST40EF PSU Review: Power Through Efficiency

Cases & PSU/Power Supplies by Berry @ 2006-12-08

Equipped with a new generation of design and components, the Element ST40EF continues SilverStone´s stride toward more efficient power supplies, with higher than 80% efficiency across all loading conditions.

External Looks

Looks

As for most things in life, first judgement is done mainly on the looks. SilverStone wanted to make sure the shipment came over secure, as it was shipped in a 50x50x50cm over box, and wrapped in approx. 50m of foam. Opening the box, the package looks unharmed.

The looks are as one would expect from SilverStone: stylish and to the point

Opening the box, you’ll find the power-supply, accompanied by an 18AWG power cord, the manual, and 4 black screws. First thing you’ll notice when unpacking is the huge weight. With almost 2,2kg it isn’t a light-weight.

As for connectors, there are more than plenty, and with cable lengths of 50 cm for the first connector it is suitable for almost any case. The power supply comes with a 12V ATX connector only, so if you need an EPS connector, you’ll need to do some modding, or apply a special bridge. The supply is cooled by a 12cm temperature controlled fan, and hot air is pushed out the back side.

On the side is the sticker with the tech-specs, and all the other things you’ll want to know, as the CE-brand, US.R. number etc.

Enough about the outside though, time for the Internals ->

Comment from Feargeber @ 2006/12/13
ooh, I read this article about the ST40EF. Very nice.

I think this will be my next PSU for my HTPC case. Sounds very good.
I wanted to kick out my old Noname PSU in any way, as it is getting too loud.

Now I read, that even efficiency is very interesting in new PSU's.
over 80%, thats great, I do not want to know, how less efficiency my noname has......

Thanks for the Review and the informations guys.
