Corsair CS Series Modular 650W Power Supply Review

Manufacturer: Corsair

A Detailed Look

View Full Size

The Corsair CS650M power supply features a scratch-resistant black matte finish and measures 140mm (5.5”) deep so it should fit in virtually any case. The unit incorporates a single 120mm fan for cooling and the cables are a combination of fixed and modular.

The backside panel features an open grill and includes a power receptacle and master On-Off switch.  The honey comb grill allows air to exhaust out of the power supply for cooling the internal components with minimal turbulence and noise.

The CS Series 650W modular power supply uses a 120mm Hong Hua fan (HA1225L12S-Z). The fan incorporates sleeve bearings and is rated for 0.33A at 12 VDC.

In addition to the two fixed cables, the front panel contains five modular receptacles. All of the modular cables are flat, ribbon-style to help minimize air resistance and maximize case airflow. The cables are nice and long, with the two PCI-E cables measuring 29.5” long (750mm) and the 4+4-pin ATX/EPS cable measuring 26” long (650mm).

Under the Hood

Corsair appears to be using a new OEM (Great Wall) for the CS Series Modular power supplies. The PSU uses DC-to-DC converters to create the 3.3V and 5.5V outputs from the +12V rail.

The dual main capacitors (Nippon Chemi-Con) on the primary are rated at 270uF, 400V, and 85°C.  The secondary features a combination of electrolytic and solid polymer caps for filtering.

Does it support the new super-low power states Win 8 is capable of ?
