Under the Hood

Here are a few pictures showing the layout and components inside the new Kingwin STR-500 fanless power supply. Kingwin appears to once again be using SuperFlower as the OEM for the STR-500, the same company that builds their Lazer Series Gold and Lazer Series Platinum PSUs.

Once the large external heatsink is removed, the internal layout looks very similar to Kingwin’s Lazer Series Platinum LZP-550 PSU. The top surfaces of the internal heatsinks are fitted with thermal pads to conduct heat into the external heatsink when attached.

The primary capacitor is made by Nippon Chemi-Con and rated for 470uF, 400V and 105°C with a combination of solid polymer and electrolytic caps also made by Nippon Chemi-Con populating the secondary side.

The overall layout, build quality and component selection looks very good.
