Under the Hood
Here are a few pictures showing the layout and components inside the Nexus RX-5300 – 530W power supply. Nexus appears to be using ATNG Power Co., Ltd as the OEM for this unit and the overall build quality appears to be very good.
The main capacitor on the primary is made by Teapo and is rated at 270uF, 400V, and 85°C. The main bridge rectifier is located to the right of the large choke coil.
