Internals and Electronics
Sirtec (High Power) is the manufacturer of the Hive-series. There are two thin heatsinks and one remarkable yellow capacitor (top right), which are typical components for Sirtec power supplies. The PCB for the modular ports is isolated by a thin plastic sheet since it's very close to the main PCB. The mainboard consists of epoxy resin and laminated paper. This doesn't apply to the small PCB with the PWM/PFC control (CM6800TX). All capacitors are made by Teapo so the main cap is not a Japanse one. For +3.3V and +5V regulation this PSU uses a magamp. A safety IC from SITI (PS223) offers OVP, UVP, and 4-channel OCP. The EMI filtering includes all the important components.
