Upon cracking open the VENGEANCE 550M, we find that it utilizes the same Hong Hua HA1225H12S-Z rifle bearing fan that the others used. It’s rated for 12VDC, 0.58A, @ 2200 RPM.

With the case opened, we can see that our CWT based VENGEANCE 550M utilizes roughly the same layout as the VENGEANCE 650M did.

CWT’s been doing better when it comes to the soldering side of things. This sample does look a bit cleaner than the 400W unit I previously looked at.


Behind the AC receptacle, we find the start of the line filtering, two Y caps, and one X cap. On the right, we have the remaining components of the line filtering, three coils, two X caps, two Y caps, and a MOV hiding under the goo…



Here we’re taking a stroll around the VENGEANCE 550M. From this angle that primary cap sure looks a lot smaller than the one used in the VENGEANCE 650M.


Looking at the modular interface PCB, we have several polymer caps from Apaq and NIC. At the lower right, we also have a Weltrend WT7518D protection IC. I’d normally say that the solder side doesn’t look too bad, but this time around it doesn’t look to clean but the actual soldering looks to be solid.

Moving along, we find a GBU1006 bridge rectifier all goo’d up.

Yup, that Nippon Chemi-Con 400v220µF cap looks to be at least a third shorter than the 400v330µF used in the VENGEANCE 650M. At least Corsair is consistent in using the KMR series 105°C rated primary caps in all four of our tested units.


On the left, we have an STTH8S06D recovery diode and a pair of Fuji Electric 20N60S1‘s. On the right, we have a pair of 5R280CE‘s.

We’ve got several smaller Nippon Chemi-Con electrolytic caps spread around the main PCB. Our standby is provided by a CEF04N7G IC that is standing at attention..


Our +12V is handled by three power-transistors located on the middle daughter-board. One is a 028N06NS, and the other two are 039N06NS‘s.


There’s a few more Nippon Chemi-Con’s on the secondary side. We also spot what appears to be a few Nippon Chemi-Con polymers.

Hiding down at the base of the middle daughter-board we have an MBRQ2045CT goo’d to a cap. Is someone at CWT trying to implement an example of “busting a cap in your A$$” with this setup?

We locate our VRM on the daughter-board that’s located on the secondary side. Man, this looks just as bad as the back of the modular interface board did. Anyways, located in the center we find the APW7159C acting as the controller. We also find three M3004D’s and three M3006D’s, which provide our minor rails.


On the left located just behind the coil is our PFC/PWM combo controller, the CM6800TX. Over on the right, we have our protection IC, which is a PS229.
