Silver Power SP S460FL 460W Review (Fanless PSU)

The Silver Power SP S460FL 460W is a product that we weren't expecting to review this month. We are glad however that we managed to slot it into the busy review schedule because it is a stellar design by OEM partner Seasonic.

Cosmetically, first impressions were not good, because the box artwork is simply dire. No offense to Silver Power, but first impressions can really matter, especially in a retail store environment. The roaring, angry Gorilla is sending the wrong image to the potential customer.

Inside the box, the bundle is comprehensive and immediately reassuring. The power supply is protected in a heavy felt bag and we particularly like the dual pouch storage container and the high grade modular cabling.

Technically, the design is exceptional. Noise suppression is as good as we have seen, peaking at just 25mV on the +12V rail at full load. The +3.3V and +5V output are just as impressive, peaking at 10mV/15mV respectively.

The fanless operation and pure modular design makes this power supply ideal for a media center build, or high grade, silent office machine. The excellent efficiency performance also ensures that the system can be left on 24/7 without excessively draining power at the socket.

The retail price of this supply is a whopping £109.75 inc vat. It is the most expensive power supply under 500W that we have tested to date. I do feel however that it is a specialist design targeting a small audience who want the ultimate quality, with pure silence.


  • silent.
  • efficient.
  • modular.
  • technically exceptional.


  • Do we really need a roaring Gorilla on the front of the box?

Kitguru says: This came from nowhere, and has grabbed our attention. An excellent power supply, ideal for an efficient media center. Be prepared to pay however.
