As you may have noticed, the model number of the PSU I’m testing has a PF at the end. This means that the PSU have built in power factor correction. Power factor correction improves the efficiency of the power distribution, i.e. when you are distributing electricity you loose a fraction of it when you transport it around the power grid. With PFC, you minimize that loss. The loss you experience is normally lost as heat. There are two types of PFC, Active PFC and Passive PFC. Active PFC uses a circuit to correct the power factor, while passive uses a filter on the incoming AC input. Active PFC is more efficient than passive, but it is also more expensive. The FSP350-PN(PF) uses passive PFC to keep costs down.
..To sum it up, the Fortron Source FSP 350-PN(PF) is a VERY good buy. It offers solid performance with little noise at a very attractive price. There are better PSUs on the market, but they cost a lot more, and the proven reliability of Fortron Source PSUs in the OEM market should be factored into your buying decision as well. I can highly recommend the Fortron Source FSP 350-PN(PF) for anyone that don’t have $100 to spend on a PSU.
