    True. But even the SF600 Gold (never mind the Platinum) performs better than the EVGA 600W. So only if you're purely looking at wattage and nothing else.....

    Can you derate one so I can run it passively please?

    That's not out of the question.

    Seconded. Passive SFX (not -L) would be incredible.

    You'll need something like a µATX one with two graphics cards and SLI with two high end ones...

    So where would be the point of such a thing?
    A Replacement for normal ATX in "tight situations" like a Cooler Master Elite 130 so that you can use a bigger heatsink...

    PS: If you wanted to you probably could do something like the Silverstone Raven RVZ01 with µATX Board compatibility...
    The SF750 is going to be perfect for HEDT systems in the Cerberus and Cerberus X cases. To be fair, those are boutique SFF cases. Very niche.

    With more SFX PSUs like these, cases such as our upcoming CS381 Micro-ATX case could benefit from having more choices for the users. Unlike other Micro-ATX cases on the market now that can fit ATX PSUs, it was designed to fit only SFX / SFX-L PSUs for size saving.

    Anyway to know what the total capacity is for the SF750, Jon? Ideally the combined output should be over 100W to support up to eight drives that the CS381 can accommodate.

    Total capacity of the minor rails? If so, it can easily handle up to 8x drives.
    I haven't met a PSU so far that can only deliver 100W on the minors even if the paper specs state so. All have much higher OCP triggering points.

    Passive is nice, but open or closed case?

    Come to think of it... that might be hard in SFX. There's very little surface area and the application of SFX in a build is typically into a tightly cramped place with little to no air flow.

    Given the successful direction of power density, I would say that you could take the SF and put it into an ATX housing without a fan. And that would give you enough space around the electronics for passive airflow and enough surface area around the housing for sinking heat, but I think a realistic number for a fanless SFX using today's tech is only about 450W. If we could hit Titanium efficiency, we could see 550W... but the unit would be very expensive. Not impossible. Just expensive.
