SilverStone Extreme 1200R Platinum PSU Review

Looking for a high-end but compact SFX-L power supply? This could be just the thing


  1. My friend has an older version and its silent too. great for a silent system build. rather costly though and hard to get here. (import needed)

  2. While it looks bad on some of the test, most people wouldn’t even notice the technical things mentioned in this review. looks like a great supply and almost silent. id buy it. I have an old OCZ PSU and it drives me nuts. Only negative is the 125 asking price. £90 would be acceptable IMO. time to trawl the net.

  3. I bought some of their fans for my media server months ago. forget Noctua, these are the best out there.

  4. the plastic casing is bizarre. seems over elaborate for a PSU in places. especially the plastic hooks to lock them into place.

  5. Very expensive for what you get.
