Final Thoughts and Conclusions
Seasonic continues to make incremental improvements to their new Platinum 400/460/520 Fanless power supplies, which result in 80Plus Platinum efficiency, extremely tight voltage regulation, and clean DC outputs. Add to that a 7-year warranty and a good assortment of all modular cables and you have one more very good power supply. Fanless power supplies occupy a niche market and won’t appeal to everyone but if you need/want a truly fanless unit, one of the Seasonic Platinum Series Fanless PSUs will be hard to beat!
The Seasonic Platinum Series Fanless 460W power supply is currently selling for $134.99 USD (Newegg.com, February 2013).
Strengths:
• Fanless operation (0dBA)
• Excellent efficiency across a broad range of loads (80Plus Platinum certified)
• Excellent voltage regulation
• Low AC ripple even at 100% load
• Single +12V output can deliver up to 38A/456W
• Two PCI-E connectors (6/8-pin) and one 4+4 pin/8-pin ATX/EPS 12V
• 7-Year warranty
• Active PFC with universal AC input
• All modular, flat ribbon-style cables with gold-plated connectors
• Excellent build quality
Potential Weaknesses:
• Fanless operation still requires good case air flow
• 80Plus Platinum Efficiency + Fanless = Relatively Expensive

Is it really silent? Yes,
Is it really silent? Yes, there is no fan, but it can produce a long pi sound when working under load.
I have heard this that is why it is difficult to decide. I want to have a completely silent computer, but what if this PSU doesn’t work as expected when it arrives? There is a Thermaltake Tt Toughpower DPS G 550W – I am looking for it on hardware.nl or amazon which should be great too – it has a 140mm fan. Well, it makes some sound. So, this is like a lottery, I think…
