Tagan EasyCon XL 700W: A Tagan at Last

The cover pops off to reveal a densely packed PCB with the promised twin transformers in the middle flanked by two black anodized heatsinks. There's not a lot of space for airflow between the various components, and it's easy to believe that heat buildup could be a problem without the side vent shown on the previous page.

Twin transformers in the center.

Although the rear grill is very open, a significant portion of it is blocked by a secondary PCB (probably the PFC circuit) that rises vertically just behind the power socket.

Cable sets are neatly organized and isolated from each other with heat shrink.

The heatsinks are chunky enough, and numerous fins provide plenty of surface area. Our only concern is fin density: The fins are packed tightly and there is little room for air to escape. A low speed fan may not provide enough pressure to force air through the power supply.

A small secondary heatsink provides additional cooling.


Tagan branded, but the model number shows up in Globe Fan's database.

The EasyCon XL is one of a few recent power supplies to use a fan larger than the usual 120mm (or 80mm) size. Its 135mm fan is about as large as it is possible to fit within the confines of a power supply.

The fan is branded with Tagan's logo, but a search for the model number revealed that the fan is manufactured by Globe Fan. It uses ball bearings, and is rated for a noisy 2200 RPM and 46.2 dBA. There's not much hope that it will be quiet at higher speeds, but perhaps the starting voltage will be low enough to keep it quiet when it starts.
