SilverStone Uses Another OEM To Upgrade The ST45SF To V3.0

News
By published

SilverStone revamped its mainstream SFX units with newer versions made by another OEM. The ST30SF and ST45SF v.2.0 are now made by Sirfa/High Power instead of FSP. The older models will still remain available, at least for a little while.

Shortly after announcing the new version (v.2.0) of the ST30SF unit, SilverStone revealed that the ST45SF unit has been upgraded to v3.0.

The cable configuration remains exactly the same in the new ST45SF unit, while SilverStone continues to include in the bundle an SFX to ATX bracket, which will be valuable to users who want to install the PSU in a normal ATX case instead of a mini-ITX one.

For most of you, the use of a larger fan with 92mm diameter in the v.3.0 unit is what matters the most because it will operate at lower speeds, restricting the PSU's noise output. Moreover, SilverStone told us that for a period at least both versions of the ST45SF will be available for purchase. This is why it states in the product's page that the v.2.0 has greater 3.3V and 5V output and higher temperature rating of 10℃ ~ 50℃ for NAS/storage focused systems or industrial PCs (IPC), while the v.3.0 has greater +12V output and lower noise for home desktops or gaming PCs. In our opinion the v.3.0 is they way to go, because in addition to the larger fan, it is also better protected and has stronger +12V and 5VSB rails.

    "which will be valuable to users who want to install the PSU in a normal ATX case instead of a mini-ITX one."

    Should read "which will be valuable to users who want to install the SFX PSU on the standard ATX PSU mount found on the majority of PC cases."

    Not many "m-ITX" cases require a SFX PSU. In fact, even Silverstone chose to go with an ATX mount on their SG-13 refresh of the SG-05.

    Yes you got a point there, although personally when I hear m-ITX my mind goes to SFX units since besides small dimensions, also have short cables which are perfect for such small cases.

    I need a power supply unit for my mopping robot that I use for cleaning the home floor. It has recharge dock, but recently it not working fine. In fact, it cannot charge the battery of the robot. Please advise me a suitable power base for the house cleaning robot. <a href="http://www.moppingrobot.com?rel=ugc">Mopping Robot</a>
