The Thortech Thunderbolt Plus 1200W uses a Global Fan (model RL4Z B1352512HH-3M). This is a 135mm x 135mm x 25 mm unit with eleven blades. It is a ball bearing design rated at 12v, 0.45A. The image above shows a partial plastic covering which is designed to force air in a specific direction over the components.

This is a modified High Power/Sirfa design. There are many black heatsinks inside which separate the components – it is crammed inside the limited space. The overall design is very clean and soldering quality is good.

The AC receptacle houses the transient filtering stage – there are two Y caps and a X cap here. The main PCB is home to a single X and two Y Caps, two chokes and an MOV. The primary capacitors are supplied by Nippon Chemi Con and are rated at 470µF each, 400V @ 105c.

The secondary side synchronous design is used with two DC-DC converters for the production of the minor rails. Nippon Chemi Con and Rubycon are also responsible for most of the polymer and electrolytic capacitors in the secondary stage.

The daughter card pictured above controls the iPower Meter thanks to a micro controller which can be seen on the right side of the PCB.
