Specifications and Packaging


FSP 520W Modular PSU Nameplate

Each of the FSP power supply modules are rated for a continuous output power of up to 520 watts at 50°C and incorporate a single +12V output listed at 43.3A (519.6W). Note that the modular power supplies also include a +5VSB output.

FSP Twins 500W PSU Nameplate

When two of these modules are combined into one Twins 500W unit, the combined total output power is listed as 500W. Circuits inside the common frame combine the outputs of the two modular power supplies and also generate the +3.3V, +5V, and -12V outputs. Note we now have three separate +12V outputs (thanks to the onboard current limiters), each rated at 16A.  The PSU includes universal AC line input (100-240 VAC, 50-60 Hz) and active PFC, which makes the unit more environmentally friendly to the local power grid.
