Corsair are using a Ong Hua fan, a 14cm model (HA1425H12B-Z) with 7 blades. The fan is rated to spin at a maximum of 2,800 rpm. We have seen versions of this fan in several OCZ power supplies before.

The CWT design has been well put together and we immediately notice very few heatsinks inside the unit. The more efficient designs can make do with fewer heatsinks.

The Corsair custom CWT PCB is shared between the 750W, 850W and 1050W models. The company have clearly opted to use high grade components, selecting 105C rated Japanese capacitors on both primary and secondary stages. Corsair claim this power supply can deliver a continuous power delivery at a temperature rating of 50c.

The cables are sleeved and tied into the chassis with a protective plastic covering. This will ensure that no fraying can occur over the long term.
