Seasonic are using a Hong Hua 135mm fan, Model number HA13525H12F-Z – the same model featured in the PRIME 1000W Platinum. This is a Fluid Dynamic Bearing Fan selected for low noise characteristics. Regular readers may recall that the Seasonic Snow Silent 750W unit shipped with a smaller 120mm fan from the same company so its a good move that Seasonic are adopting larger fans.
Larger fans of similar quality are able to push more air at the same speeds, likely often spinning slower to reduce noise emissions. This fan is rated at around 150,000 hours at 25c.

The overall build quality is very high, as we would expect from Seasonic. Soldering quality is stellar and there are several little heatsinks in key positions, to help deal with heat. Due to the high efficiency rating of this particular unit there really is no need to over populate the internals with an array of heatsinks.
Seasonic are using high grade 105c rated Japanese capacitors in both primary and secondary stages – always reassuring to see, if expected at this price point. The two primary capacitors are rated 400v 470uF, along with a bigger 400v 680uF model from the same family. This gives a total of 1150uF.
It is interesting to note that the 850 watt Titanium PRIME model (reviewed in August 2016 HERE) has actually a greater uF output than the 1000W Platinum model. The Titanium 850W model used a 650uF and a 450uF capacitor in the primary stage for a total output of 1100uF. The Platinum 1000W uses a 400v 450uF and a 400v 560uF capacitor for a total of 1010uF.
Seasonic do tend to greatly over specify their power supplies. We reviewed a Super Flower 1000W gold unit this month for instance and it was equipped with two 470uF capacitors for a total of 940uF.
By comparison the staggeringly expensive Cooler Master MasterWatt Maker 1200W MIJ unit which we recently reviewed (HERE) can deliver a total of 1450uF from both capacitors. One of the highest capacities we have seen.
