Delivery and Specifications

Delivery
Cable	Length
1 x ATX 20+4 pin	60 cm
1 x EPS/ATX 12V 4+4 pin	65 cm
2 x PCI-E 6+2 pin	75 cm
2 x 3 SATA	64 cm
1 x 4 Molex + 1 Floppy	88 cm

For a power supply that offers 600 Watts of continuous output power the number of connectors is ok. However we would like to see two additional 6+2Pin connectors, since this PSU could already be used for low end SLI setups.

The CX600M has been 80Plus Bronze certified, which means that this PSU is able to reach a maximum efficiency above 82 percent at 20% Load, 85% at 50% Load and 82% at 100% Load. Furthermore this PSU complies with ErP guidelines (Energy Rated Product) and therefore it consumes less than 1 Watt when an attached system is powered off or in standby. Following we show you the feature list:

• 80Plus Bronze
• ErP
• OVP, UVP, OCP, SCP, OPP
• Dimensions (W x H x D): 150 mm x 86 mm x 140 mm
• Warranty: 3 Years
• Price: 75 CHF

Corsair's CX600M is based on a CWT OEM design. The first hint for a high-quality power supply you can get from the transient filtering stage. It is recommended to use two ferrite coils, two ceramic capacitors (Y caps), one metalized polyester cap (X cap), one metal oxide varistor (MOV) and eventually a Fuse. If you have a very low-end PSU in front of you, you'll see that the MOV and the first ferrite coil are missing. A closer look at the CX600M reveals that it has been built according to the recommendations we've just mentioned including the Fuse.

On the primary side you find a GBU1006 rectifier. Right next to the rectifier you can find a PCB housing the CM6800. The CM6800 controls the PFC Booster and the Push-Pull converter. This PSU has a Push-Pull topology using two Mosfets and two Diodes according to the following primary sided principle: link
This is an old school standard topology; simple and proven, but it won't achieve new efficiency records. Because this topology requires hard switching from the Mosfets (Switching Mosfets under voltage and current generates losses) this topology is more and more replaced in the PC PSU market by resonant topologies. The transformer has on the secondary side two coils one for 12V and one for 5V. 3.3V is generated from the 5V Coil. This is the classic old PSU topology.

The APFC Capacitor with 270uF at 400V and 85°C from Panasonic is of much higher quality than the Chinese SAMXON which can be fround in the CX430. The PFC Booster uses a STTH8S06 Ultrafast recovery diode. This is ok for a PSU in this price range; SiC Diodes are still quite expensive. The Push-Pull uses STW14NM50 (550V 320mOhm) Mosfets. For rectifying 12V four PFR40V60CT (2x20A, 60V, 0.51Vdrop) Schottky diodes are used. Regarding the rectificaton of 5V two STPS3045 (2x15A, 45V, 0.63Vdrop) are used. The Output filter Capacitors are from CapXon. 105°C is written on them.

The OCP, UVP, OVP is done by a PS229.
