Silverstone ST45SF

SilverStone ST45SF

This week, a very small package came was dropped off on my doorstep by FedEx. At first I thought it was more Gloria Jean's coffee for the Keurig coffee maker, but it turns out that SilverStone's latest SFX power supply was inside of this package. SFX power supplies are used in MicroATX and FlexATX chassis. They're considerably smaller in size than ATX power supplies and because of this they tend to be lower power. Typically SFX power supplies are around 300W. This SilverStone, on the other hand, is a 450W unit. Looking at the specs on the side of the box, we can see that SilverStone opted for the lead-free black paint on this particular unit. That's good as I have a tendency to suck on power supply housings and really can't afford any further drain bamage. We also see how small this unit is before we actually open the box. 125mm x 63.5mm x 100mm. That equates to 4.92" x 2.5" x 3.93" for those lead paint eating individuals that haven't evolved to the metric system yet. The DC output capability table is also located on this side of the box. Let's put that up on an easy to read table: SilverStone ST45SF +3.3V +5V +12V -12V +5VSB 21A 22A 36A 0.5A 2.5A Max Power 120W 432W 6W 12.5W 450W This unit has a whopping 432W of power available on the +12V rail.
