Final Thoughts

Pricing

Seasonic’s Platinum Fanless 520W power supply currently sells for $140 in the USA at Amazon and £115 in the UK at Scan Computers. The Seasonic Platinum Fanless 520W comes with a 7 year warranty.

Conclusion

Having already tested this same power supply under a different brand name I think it is fair to say I already knew it was going to be good. Indeed, after re-testing I’ve found this power supply is still excellent and nothing has changed in that regard, there is a bit of variation but nothing significant. The Seasonic Platinum Fanless 520 features some of the best ripple suppression on the market, impressive voltage regulation that easily falls within Seasonic’s +-2% claims and we’ve also got excellent 80 Plus Platinum efficiency and high PFC to complement those things. This power supply is further improved by the fact it has a fully modular design and comes with lovely cables: they are all black and where braiding is used it is decent quality. Furthermore, the overall construction, build quality and use of components is top-tier and that’s all backed up by a 7 year warranty to give you peace of mind. The only possible concern with this power supply is that it is expensive – but find me a fanless 500W+ power supply that isn’t! Especially with this kind of quality and performance. I am a little more inclined to pick Seasonic’s 520 Platinum Fanless PSU over the rebadged versions sold by other vendors because Seasonic offer a longer warranty, a better accessory package and more luxurious packaging.

Pros

Silent operation
Excellent voltage regulation as promised
7 year warranty
Lovely cables and fully modular
Use of high quality components
Pleasing accessory package
Excellent efficiency and PFC

Cons

Is rather expensive for a 520W PSU

“It’s silent, it performs great and it looks fantastic ….so there are no marks for guessing it is made by Seasonic! If you’re in the market for a high quality fanless power supply then Seasonic have got you covered with their Platinum 520. “
