FSP Group, one of the leading manufacturers of power supplies for computer as well as for other household, industrial and even medical equipment, is better known to people who are assembling computers. This company is just mostly turning out OEM products, shipping them without colorful boxes, long user guides and enticing ads that off-the-shelf products from better-promoted brands come with.
Anyway, the excellent reputation of power supplies from FSP Group (also known as Sparkle Power or SPI Inc.) compels me to write a review about them. Because if you are looking for a good and solid power supply without those freakish Christmas-tree-like lights, then such products may be just what you need.
The units from FSP covered here can be divided into three categories by different versions of the ATX standard (as you remember, these versions differ mainly in the distribution of the load across the PSU’s power rails and, starting from version 2.0, in the replacement of the older 20-pin mainboard power connector with a 24-pin one).
First, we’ve got two inexpensive models of the ATX12V 1.2 standard that can be referred to as the “GTF series” (by the suffix in the model names). Despite the declared wattages of 300 and 350W, their allowable load currents correspond to the standard’s requirements to 250 and 300W units, respectively. Besides the main label, there was also a sticker with the text “+12V/18A MAX” on the 300W model, so I thought it proper to put two load currents into the table above. I will dwell upon this point in more detail below.
The next three units are a step above the previous two – they comply with the ATX12V 1.3 standard that features a higher load capacity of the +12V rail. By the way, don’t be surprised to see the Zalman ZM400B-APS here. This power supply is actually manufactured by FSP Group and is fully analogous to the FSP400-60PFN model. The three models all exceed a little the requirements of the standard (I put the requirements to the 300W unit into the table for the sake of reference since this version of the standard doesn’t describe units of a higher wattage).
The last three PSU models belong to the latest version of the standard, ATX12V 2.0. So, they have two +12V outputs, and there are two numbers in the corresponding column of the table, the maximum load capacity of a unit on the +12V rail equaling their sum. To be exact, the top model, FSP460-60PFN, formally belongs to the server standard EPS12V and is targeted at entry-level servers. But from the home user’s point of view it doesn’t differ from an ATX12V 2.0 power supply: it has the same two +12V outputs and a 24-pin connector for the mainboard, too. These three units all fully comply with the requirements of the standard.
