Endorfy are using a Fluid Dynamic Bearing (FDB) fan in this unit, one we have seen before in 2023 – in the Supremo FM5 Gold 1000W PSU. This fan is rated at 1,400 rpm, 12V, 0.15A. Its a 120mm fan with a speed range between 600 and 1,400 rpm.
The MTBF (mean time before failure) is rated at 100,000 hours, which is a pretty standardised rating. This is a good fan and based on previous experience it does run fairly quiet if the fan profile is configured properly. There is no partial plastic panel on this to direct airflow over specific components which is a little unusual.
We can see that Endorfy are using SAMA as the OEM for the design, with clearly some design decisions in place by Endorfy themselves. The PCB soldering is very clean as you can see by the images above when we disassembled it and Endorfy are using some quality components throughout.
The primary stage adopts a high quality 105c rated Nichicon capacitor, rated 1000uF, 400V. Nichicon are quality capacitors, and we always like seeing them as well as other Japanese brands such as Nippon Chemi Con and Rubycon.
This is a APFC, full bridge & LLC Resonant converter design with Synchronous Rectification and DC-DC Convertors to generate the secondary rails. Filtering capacitors are from companies such as Nippon Chemi Con and Rubycon across the design. Transient filtering is 6 x Y caps, 3x X caps, 2 x CM chokes and a single MOV.
This power supply offers OVP, UVP, OCP, SCP, OPP, SIP and OTP protections.
