Corsair ditched their usual fan supplier, Yate Loon, for a San Ace 120mm fan from Sanyo Denki. The dual ball bearing fan is very reliable and with a very wide operating range (5V to 13.8V), capable of reaching a maximum speed of 2200RPM. If you ask us, it is ironic to be using such a powerful cooling fan inside a unit which will even run fanless.

And here is the moment of truth; the AX760 is nothing alike the digital models, where Flextronics were the OEM behind them. The AX760 is based on a Seasonic KM3 design and obviously Seasonic is the OEM behind its manufacturing as well. Quality wise, this was not a bad choice since Seasonic always does a great job with high performance units, with the AX760 being no exception to that rule; we could not find a single blemish inside this power supply, be it a weak structural point or a bad soldering spot.

Behind the shielded A/C receptacle the input filtering stage starts, with more parts on the main PCB. The filtering stage is very healthy as we counted six Y-type capacitors, three X-type capacitors and filtering coils, as well as a surge suppressing MOV. Next to the filtering stage we can see the two input rectifying bridges, both attached to a small dedicated heatsink before the APFC circuit starts.

The larger heatsink of this power supply holds the active components of the APFC circuit and is located near the edge of the unit. Two Nippon Chemi-Con KMR 420V/330μF 105°C capacitors and one average coil are the large passive components of the APFC, right before the primary inversion stage. The four primary stage transistors form a full bridge topology and are all attached on the relatively small heatsink before the main transformer.

Many capacitors can be found on the secondary side of this power supply, with the electrolytic ones supplied by Nippon Chemi-Con and the solid state ones supplied by Enesol, making this product an all-Japanese affair. As the large transformer generates only the 12V line, we expected to see DC to DC circuits for the 5V and 3.3V lines; however, Corsair (or Seasonic) moved the DC to DC and VRM circuits up to the PCB which holds the modular cable connectors, merging regulation and distribution.
