Seasonic are using an ADDA AD1212HB-A70GL fan in this unit – they are a Chinese brand. This is a 120mm ball bearing fan rated to 75CFM at 42dBa. Fan speeds are rated up to 2,200rpm. As the S12G is a 80 Plus Gold certified power supply we wouldn't expect the fan to spin at these speeds, even under extreme duress.
The build quality is excellent and the overall design is very similar to the G Series units we have tested in the past. Obviously there is no modular PCB on one side of the chassis. Soldering quality on the main PCB is also at a very high standard.
The non modular cables are sleeved into the chassis, and tied down in multiple places to protect them against fraying.
Filter starts with an X cap, four Y caps and a coil. On the main board is a TVS diode, two Y caps, an X cap and two coils.
The daughtercard above holds the PWM controller, which is an ICE2Hs01G.
The primary capacitor is Nippon Chemi Con – a high grade Japanese model rated in this unit – 420v 470uF 105c. All electrolytic secondary side capacitors are Nippon Chemi Con or Rubycon which is reassuring.

Nice review guys. However I always end up thinking that it would make for a much better test&review to go for the middle to low-wattage option of such series. To me it seems those in need of multiple 8-pins EPS and “dozens” of PCIe 8/6pins all to often would go for a modular power supply. Just my 2 cents but maybe something to convey over to the manufacturers supplying the goods?
the only thing working against it is the fact it is not modular – good review, thanks.
£99.99 for a 80 Plus Gold with those specs is impressive, always like seeing nippon chemi con – never had one of those capacitors fail on me in 20 years 🙂
@Kitguru: How would you guys compare this to the Seasonic 80 Platinum series (SS-760XP2, or SS-660XP2)?
just got this and i think ill be very happy with it
