    Default Did Seasonic use the Focus Plus platform for their new lower wattage Prime Ultra's?

    As the title stated. Did Seasonic just use Focus Plus Gold and Platinum power supplies for their new Prime Ultra Gold and Platinum 550W till 750W?

    Because if you look at Seasonic's site, it just looks like the same PSU internally if you look through the back of the PSU.

    New Prime Ultra Gold:
    https://seasonic.com/product/prime-ultra-550-w-gold/
    https://seasonic.com/product/prime-ultra-650-w-gold/
    https://seasonic.com/product/prime-ultra-750-w-gold/

    New Prime Ultra Platinum:
    https://seasonic.com/product/prime-ultra-550-platinum/
    https://seasonic.com/product/prime-ultra-650-platinum/
    https://seasonic.com/product/prime-u...50-w-platinum/

    Seasonic Focus Plus Gold:
    https://seasonic.com/product/focus-plus-550-gold/
    https://seasonic.com/product/focus-plus-650-gold/
    https://seasonic.com/product/focus-plus-750-gold/

    Seasonic Focus Plus Platinum:
    https://seasonic.com/product/focus-plus-550-platinum/
    https://seasonic.com/product/focus-plus-650-platinum/
    https://seasonic.com/product/focus-plus-750-platinum/

    Looks the same to me, especially if you compare it with higher wattages Prime Ultra and the older Prime units.

    Seasonic Prime Gold:
    https://seasonic.com/product/prime-650-w-gold/
    https://seasonic.com/product/prime-750-w-gold/

    Seasonic Prime Platinum:
    https://seasonic.com/product/prime-650-platinum/
    https://seasonic.com/product/prime-750-w-platinum/

    Higher wattage Prime Ultra:
    https://seasonic.com/product/prime-ultra-850-w-gold/
    https://seasonic.com/product/prime-u...50-w-platinum/

    And then there is the of course the 80PLUS certificate which is identical...

    Did Seasonic just become the first manufacturer to sell the same power supplies under different names and for different prices to let you pay for the 2 years longer warranty?

    I don't think so. But we can't be sure about the Prime Ultra until we spot some reviews.
    I just bought a Prime Gold 650w and inside it looks like the platinum one like here
    It has the same layout, but the APFC coil is like in the pictures below. The capacitors, the radiators between main transformer and modular board are the same with Platinum one not like in the Focus one. I'm wondering what's with that difference of the efficiency between Platinum and Gold since apparently share the same platform. I think is the lower quality MOSFETS on the Gold one.
    Sorry for the quality.

    tbh, I trust the Focus a bit more than the prime because the first has the +5VSB far away from +12V rectifiers, the Prime has it close to each other like its predecessors.

    Still, from "behind" Focus and Prime look very similar. And it is also possible that they used mockup samples for the photo shoot...

    But is strange enough the 550w model from the Ultra series. At the older Primes the 650W was the minimum. And the efficiency numbers from ecova. But with that numbers is a little question. It's all perfect until the last digit, like someone was make copy-paste. I think it should be a little difference if were made other tests with the new platform of Ultra and if has a different platform and not the Focus one..

    Yeah, I think you're right. Those photos are clearly original (as opposed to just photoshopping different labels on the same PSU across multiple series), and yet they indeed show same input filter there.

    There's also a table I took from some documents about Seasonic's rebranding:



    Notice how PSUs with same power and platform are grouped together, and Seasonic Focus Plus Gold (SSR-550FX) is on the same row as Prime Ultra Gold (SSR-550GD2). Also as a side note, there are units made for LDLC, Phanteks, Antec and XFX in there too. (And what brand could "HK750-x" be, where x can be 90PP or 92PP?

    It is surprising because I thought Prime Ultra were just Prime with minor changes. Maybe Seasonic Rep can chime in and say that maybe only the low wattage Prime Ultras use the Focus Plus platform (like you say), or something similar.

    Notice the chassis size. The PRIME Gold 650W has a deeper chassis than the PRIME Ultra Gold and the Focus+ Gold, which have the same size.

    Yes, it seems that the platforms are the same.

    That can't be a coincidence...

    That's how Huntkey names some of their power supplies.

    That's what they said, but I guess that's only true for some.

    Never assume about identical PCBs from safety docs. They do not always reflect reality.

    Worst example: Tagan, their CE doc (singular!) was like this:

    TG-0000XYZ - so any PSU from them ran under the same CE doc ....................

    Well I said it before, somewhere

    Even if it's the same platform (that much is evident, or Sea Sonic cheats with certification), that doesn't mean it's the exact same PSU.

    Also HEC did this a while back with Cougar and HEC-branded PSU based on the same platform.

    And what would be so bad about it? Focus has top notch performance. If they increase build quality to make it worth the higher price, why not? If it's identical for anything other than the housing, well then that stinks. Even though it's a lot sexier than the Focus.

    You can go buy tomatoes, but don't throw them before we see reviews.

    Seasonic Rep said that about the Titaniums, I guess it's also true for the Gold and Platinum 850W+. He wouldn't answer any query about the "Prime Focus" units.
    I hope by now he has clearance to do so, as they start showing up in stores.

    Just look at the case depth of the lower wattage Prime Ultra units. With 140 mm it's identical to the Focus Plus.

    You don't just shrink the Prime platform within a few months to be able to fit it in a 140 mm chassis. So don't expect them to be as silent as the predecessors.
