    I bet the 450w model and possibly 500w model are group regulated.
    Otherwise Seasonic would use "DC-DC converters!" as a marketing point, noticing how they include "double forward converter design".

    Looks like a different internal design.

    The lack of OTP and OCP is also disappointing. Every power supply should have OCP on atleast the minor rails. This unit probably uses the same old 8-pin HY-510N protection IC.

    At the moment the Corsair CX still looks the better option.
    We'll just have to wait some months for reviews.

    Absolutely does and heard about it but. I'm not too Familiar and they said the DC-DC is better...it's a select handful...everything most of everything is Forward Converter/Group Regulation, most of everything. It is some shady marketing in a way and slang with topology. And we Should Issue and breakout service Schematic's for the user.

    Could absolutely Design Perfection for the User and like he wanted or needed to change a fan and got Curious lol.

    Well it is my Nature the Book and White board stuff. Very much the Technician side...And People feel Comfortable with Professional shit in the Electrical Area. Should have a Schematic for Reference always.

    PSU manufacturers don’t want users opening their units. Let alone replacing fan and caps. Releasing schematics won’t do Seasonic any good.

    They changed the specs, it now says "LLC resonant converter design"

    It also says: "For customers in the EU, the scheduled launch of the S12III series is Q3 2019"

    In the USA it's already available.

    Interesting. I went to the Seasonic website, where they indeed list this as "LLC resonant converter design."

    Someone should inform Newegg. They have it as "Double Forward Converter Design." The 450W costs $49.56, the 650W costs $54.99, and for two more days the 500W costs $44.99 with no shipping cost listed.
    CPU: Core i7 8700k, HT enabled, all 6 cores OC'd to 4.8GHz, Vcore = 1.24v
    Heatsink: Noctua NH-D15 with one NF-A15 1500 RPM PWM fan
    Motherboard: Gigabyte Z370X Aorus Gaming 7
    RAM: 4x16GB (64GB) Corsair Vengeance LPX DDR4 RAM 16-18-18-36@3200MHz, Vdimm = 1.35v
    GPU: MSI GeForce GTX 1080 DirectX 12 with 8GB 256-Bit GDDR5X
    SSD1: Samsung 840 EVO 500GB TLC; SSD2: SAMSUNG 860 EVO 1TB 3-bit MLC

    UCC/NCC make top grade capacitors

    Audio deals with 20 kHz, SMPS go a lot higher

    When I recap I have no problem using Chemicon, Nichicon, Rubycon or Sanyo/Panasonic among others; so long as they are low ESR

    Many do, you just have to pay for it and trust them.
    The thing is that most Japanese Companys are like Mercedes/BMW while the Taiwanese are more like VW:
    one only has the upperclass in their lineup, the others have everything...

    Not too long ago, the lowest car Mercedes had was the C-Class, equal to 3 series BMW, wich was also the lowest end car they had at the time (lets just talk mid 90s stuff here for convenience).
    VW at the time had 2 or even 3 cars below that:
    Polo, Golf and if you want to you can count other cars like the Jetta and Corrado/Scirocco to that bunch...

    Its the same with Caps, the Japanese usually start in the middle of the Taiwanese companys.
    For example Teapo has 2 or 3 series below the KZE Series...

    Some say the Honda Civic is about the cheapest one can get; mine is 20 years old, has over 200,000 mi and is still running just great.

    Anyhow Chemicon is Japanese
