We would like to thank Seasonic for supplying the review sample.
Seasonic’s name is well-known among informed PSU users. They provide and build most high-end models for companies with a significant presence in the field (e.g. Corsair) and don’t restrict their role to that of an OEM, but also participate as much as they can in the retail market by keeping a full portfolio of products for the end-user. They, on top of that, maintain top notch RMA service. Its emphasis is on the customer's satisfaction instead of keeping RMA approvals at a minimum to lower costs, as most companies nowadays do. As important as the quality of their products is to the company, customers who are in a bind because of a Seasonic product are just as important. Seasonic knows that the word will spread through the social media quickly if they fail to offer good support. Thankfully, more and more companies are starting to realize this fact, but not all of them treat their customers in the same way when they report a problem with the product they bought.
So far, the only Seasonic fanless unit that featured Platinum efficiency and utilized the new KM3 platform is the SS-520FL, which we have already reviewed. It earned an editor's choice award for its overall performance. The lower capacity fanless models with 460 W and 400 W, although top-notch performers, lived in its shadow because they exploited the older KM2 platform with Gold efficiency. Seasonic thought this was unfair and upgraded them to the new platform, boosting their already very good performance. In a snap, the SS-460FL, which we will have the chance to test today, uses a fully modular design and has compact dimensions: It also promises very tight voltage regulation on all rails and extra-high efficiency.
