Corsair are using the NR140HP fan inside this power supply. It is a 140mm unit and rated 12V DC 0.33A. This is a high grade fluid dynamic bearing fan that is quiet at lower speeds. This is the same fan that is in the RM850x. A small plastic strip is angled on the underside of the fan to help concentrate airflow across some of the components inside.
This power supply is produced for Corsair by Channel Well Technology (CWT). Corsair have been working with CWT now for some time and they have produced some very good power supplies over the years. This unit is a modern design implementation – half bridge topology with an APFC converter and an LLC resonant converter on the primary side. The secondary side adopted a synchronous rectification system for the 12V rail and a pair of DC-DC converters for the minor rails. Corsair and CWT adopt several daughter cards to help with horizontal spacing inside the chassis.
Soldering and build quality is high throughout the unit, just like the RM850x I reviewed recently. The two primary capacitors are Nippon Chemi Con from their KMW series. The two caps are rated 400v 470uF and 400v 560uF for a total of 1030uF. The RM850x has two 470uF capacitors, so the bigger single 560uF capacitor has been the upgrade for the 1000 Watt unit.
