SilverStone Extreme 1200R Platinum PSU Review

This unit is cooled by a Globe S1201512HBP-4M FDB fan, running at 12V 0.45A. This fan is rated to a maximum of 36dBa and claimed MTBF of 100,000 hours.

This looks to be an Enhance OEM design to my eye and the overall design is very clean, with some silver heatsinks separating sections of the board. The fan above the PCB does not have any partial plastic cover to direct air flow to a specific area as well. The unit is equipped with OCP, OPP, OVP, SCP and OTP protections.

The unit adopts Japanese capacitors and the primary stage is populated with two high grade Rubycon capacitors rated 400v 470uF each for a total of 940uF. I was quite surprised to see they were the lesser 85C rated capacitors however. In theory this should not be a big deal, even in hotter climates, but it was surprising to note in such an expensive high end Platinum power supply. When we asked Silverstone about this, they said that due to height restrictions, they opted for 85C caps in the primary stage. 105C capacitors are used throughout the secondary stage.

Soldering quality is very good on the PCB and other daughter-cards attached to the main unit.
