The models differ from the classic ATX-format power supplies in compact dimensions: the height of such a power supply is usually limited to 63-64 mm, the depth does not exceed 125 mm, and the diameter of the turntable is 92 mm. The power connectors are almost completely similar to the original ATX, which simplifies the installation and disassembly of the system when moving to a new housing.


Unlike other small-sized SFX power supplies, which are designed for economical and small-sized systems with low power consumption, Corsair SF models are not much inferior to their older counterparts. Efficiency in the region of 92%, a quality certificate of 80+ Gold and a power reserve of up to 600 watts hint to the audience that the size can be deceptive, and this crumb will playfully knock out some famous heavyweight.

And this is never an exaggeration, because despite the compact dimensions inside, these are pure high-end power supplies, which are drawn to comparison with other "golden" models of the company from the RMx and RMi series. The hardware platform of SF models built on the basis of a resonant LLC converter, Japanese capacitors and DC-DC converters and a synchronous rectifier. Such circuitry ensures the stability of all input voltages and a high load capacity of the main line +12V (100% of the nominal value).

In the model range of the SF family, it is the "golden" variations with a 7-year warranty that prevail, however, updated SF power supplies with redesigned circuitry and a "platinum" quality certificate loom on the horizon.
