Our first stop in the innards is a look at the FDB fan, naturally.

Yep, CWT built this one. Looks almost exactly like the RMi units, and the CWT version RM units that came after the Chicony versions were discontinued.

Line filtering begins with two Y caps.

CWT has their off days when it comes to soldering, but this is not one of them. It’s all fantastic today.

In this view, I see four more Y caps (two after the bridges), three more X caps (one after the bridge), and two coils. There’s also a TVS diode and yet another Y cap hiding back behind that rightmost coil and X cap. Line filtering? This one’s got it.

The PFC parts consist of a diode and three F22N60E parts. Main filter caps are Chemi-Con.

Main switchers are two G30N60Es.

Instead of the USB controller present in the RMi units, this one has a simple fan controller here above the WT7502 protection IC.

An ICE2HS01G runs the show in this unit. Being pressed for time, I was unable to pull the switcher heatsink to get a look at the PFC controller, but it’s on this board too.

The 12V output is handled by eight SM4021NAs, four per daughterboard. All secondary side capacitors I can see are Chemi-Con. So y’all no longer have the caps as an excuse to bash the unit. Not that I see it stopping some people.

Here’s a better angle showing you the cap side of the VRM, located all the way to the side of the unit. There really isn’t a whole lot of difference between this and the RMi platform aside from all the extra Corsair Link stuff.

The minor rail VRM is the same one as used in the RMi units, too. An APW7159 controls it, with M3004Ds and M3006Ds providing the outputs for the 3.3V and 5V rails.

The modular connector board is the exact same one used with the RMi units. It’s just all the extra parts are missing.

You can see this here… the connectors and fan test switch are provided for over on the right and just not present. The extra protection ICs are also not present, because they aren’t needed.

Let’s get some scoring done.
