Fractal Design Integra R2 750W Review

Fractal Design are using a Hong Sheng fan, model number A1225M12S. This is a 120mm fan, rated 12V, 1,900 rpm with maximum noise of 54CFM. This is not a ball bearing fan, but a cheaper sleeve bearing unit.

This Integra R2 750W is made by HEC. This specific design is in place to keep the costs as low as possible. They are using a double forward topology on the primary and the secondary side is using passive rectification.

The transient filtering stage starts at the AC receptacle, with two Y caps and a single X cap. The main PCB has a single DM, two CM chokes, one X cap, two Y caps and an MOV.

The soldering quality is actually very good and we see no issues in this area.

The design incorporates a SITI PS223 which supports OCP for two +12V rails.

The primary capacitor is by Chinese group TEAPO, not one of our favourite manufacturers. It is 400V, 470uF and rated to 105c.

Secondary capacitors are all TEAPO, rated at 105c. They may be using Chinese capacitors in this unit, but at least they are all 105c rated.
