Not everyone needs a monstrous 750W+ power supply unit for their everyday home or office PC, but most people would pay for a little extra in order to own a low power, high quality unit. Silverstone hope to address this with the release of the ST35F. The ST35F has a maximum power output of only 350W, more than enough for an average home or office PC which is not designed for heavy gaming or overclocking. Let us have a closer look at it and see if it’s worthy of the extra money over an OEM unit.
