The fan used in this power supply is the Fluctus 10-1037. It is rated at 1,400 rpm, 12V, 0.15A. It's a 120mm fan, with a speed range of between 600 and 1,400 rpm. This has a Fluid Dynamic Bearing and has a 100,000 hour mean time before failure.
SAMA are the OEM partner for this power supply, a company that has not featured in any review sample we have tested for a very long time. We remember way back in 2016 they released a Titanium range of units under their own brand name. They are an OEM that have tended to focus on affordable units in the past. Endorfy pointed out to us that the FM5 series is based on the custom cooling ANP920 platform. ANP920 has been designed in cooperation with Synergy Cooling.
Additionally, they are keen to highlight that due to the DC-DC conversion they can maintain stable voltage on each line separately.
The supply looks reasonably well put together and PCB soldering seems ok. It is a bit surprising to see only one capacitor in the primary stage for a 1000W unit. It is a high grade Japanese 105C rated Nichicon capacitor @ 820uF, 400V. The last Corsair 1000W PSU we reviewed (the RM1000X 80+ Gold) had two Nippon Chemi Con caps from the KMW series, rated 400V 680uF and 470UF for a total of 1150uF. There is only one large heatsink in the design as well, which is a little unusual for a high output, yet modest 80 Plus Gold rated unit.
The Endorfy Supremo has OVP, UVP, OCP, SCP, OPP, SIP and OTP protections in place.
