220-W High Efficiency Power Supply

We don’t want to forget one of the most important components we used for this reviews : Fortron’s FSP220 high efficiency power supply. As you can tell by the model number, this product was designed for a maximum output of 220 W, which is more than enough for our low-power systems. The reason we used it is the increased efficiency—PSUs will reach their highest efficiency only when operated within the output wattage range for which they were designed. Some PSUs are most efficient for low loads, while others are better for high loads. However, if you use an 800 W PSU and only use 28-50 W, the efficiency will certainly not be in an ideal range. This is why we used the FSP220—it guarantees that the PSU runs within an efficient load corridor.

We used SYSmark 2004 instead of the newer SYSmark 2007 Preview, because the latter would not finish on the test systems reliably. It also does not make a lot of sense to execute rather high-end applications on these low-end low-power systems.
