The back of the ST75F-P was reminiscent of the ST1500 I reviewed only a few short months ago - no on/off rocker switch! System builders and tweakers know the benefit of having these switches when working inside their computers. Now you must always remember to fully unplug this power supply before tinkering with internal components. Having active power factor correction (A-PFC), you will also notice the lack of an input voltage selector switch on the back too. The input is full range and will automatically adjust between 120V and 220V power sources.

I found the ST75F-P for sale as low as $131CDN. This left me quite impressed because not only was it 750 watts, but this is also an 80PLUS Silver rated power supply. The last 80PLUS Silver power supply I reviewed was the 950W GlacialPower unit a couple of months ago, which was exactly $200 more! Doing a little comparison, this new Silverstone is actually one of the most inexpensive 80PLUS Silver power supplies I could find on the market! I was also surprised to see that Silverstone chose a single +12V rail design for this power supply - that will make it a good low-cost supply to power high-performance systems and peripherals (such as SLI/Crossfire setups).

A variety of protection features are also in place on the ST75F-P, including; over current protection, over temperature protection, over power protection, over voltage protection, under voltage protection, short circuit protection and no-load protection. Despite being only $131CDN, these are the same great features we see on every Silverstone power supply, including the very expensive ST1500 that was reviewed a few months ago.
