FSP Technology offers a handy selection of desktop power supplies in their FSP-120AxxN3 series. The part numbering on these products often trip customers up however, as the different part number variations on this product resemble revision codes to many buyers. How can you tell what you’re going to get?
Refer to this chart in Page 2 of the series datasheet for a breakdown of the product variations. In short: the “xx” in FSP120AxxN3 indicates different output voltages and connector configurations. They are not revision codes, they are entirely different product variations and they are not interchangeable with each other. Make sure you select the specific product variation your application requires prior to ordering.
