A Look Inside
The be quiet Pure Power 9 is based on a FSP OEM design. A first hint for a solid power supply can be found when looking at the transient filtering stage. Here we find two Y caps and all cables have been nicely isolated.
On the primary side there is a rectifier and next to it FSP puts a PWM controller chip. Apart from that this platform is based on an active clamp SR design. The APFC Capacitor with 390uF at 420V and 85°C is from Teapo. The primary heatsink right behind it, takes care of removing the heat from a 17N80C3, a FQPF3N80C, a diode, a CET19M3Z as well as two 6R190E6. The PFC is being controlled by yet another chip. Looking for the bridge rectifier we find a GBU1506. All DC filtering capacitors are from Teapo. These aren't the most high-end caps available on the market, but they are in-line with the pricing of this unit.
The OCP, UVP, OVP is done by a WT7527.
