Corsair CS650M Power Supply Review

The 120mm sleeve bearing fan (HA1225L12S-Z) is rated up to 0.33A and 1,500 rpm at 12 VDC. There is a partial clear cover across the fan to direct the air specifically across the heatsinks.


It looks as if Great Wall are the partner for this supply. The build standards are quite good, although we have seen better. There are only a few heatsinks in this unit, but with high Gold efficiency it should be fine. The Diode bridge handles AC/DC rectification of the incoming AC voltage.

Soldering quality on the main PCB is acceptable although there are some rough traces visible.


The modular connector board is clean and the Rev S2 design uses CapXon capacitors.


The Corsair CS650M uses two high grade Nippon Chemi Con primary capacitors rated 400V 270uF, although they are not the higher grade 105C caps, but less expensive 85C variants. Secondary capacitors are all by Chinese manufacturer TEAPO, which is clearly to save some costs.

All cables are protected against the metal chassis by a rubber grommet and then tied into place.
