    Default Streacom ZF240 passive Flex ATX PSU Product Announcement

    Streacom is pleased to announce the ZF240 (ZeroFlex), a 240W, no fan, no noise, internal PSU that is based on the Flex form factor.

    The challenge has always been to supply high power, not only in a small package but also without any active cooling. To overcome this we have used extremely high quality components and developed an innovative power circuit that is more that 93% efficient. 240W may not seem a lot, but to put things into perspective, if this PSU had active cooling, it could easily run at 450W, and its still less than half the size of a standard ATX PSU.

    Even with the high levels of efficiency, heat is inevitable, which is why we have the unique ‘L’ bracket which connects the PSU directly to the case heatsink, and is designed to dissipate the heat outside the chassis. The AC socket is also mounted on a cable instead of being fixed to the body of the PSU, allowing for flexible positioning and more innovative future case designs.

    The ZF240 is compatible with the Streacom FC5 Evo, FC9 and FC10 and will remove the need for an external power supply whilst increasing the maximum power available to components.

    Full specification and pictures can be see on the ZF240 product page

    I have heard of PicoPSUs which can put out similar amounts of power :X
    Eh, 168W on 12V rail. I'm smelling some kind of improved double forward

    Well, PicoPSUs aren't SMPS. They're DC to DC, so they can be smaller. Also, this is impressive if you consider the current 240W notebook adapters out there (Dell and Alienware). Those only have one DC output cable. This thing has the full gamut of DC outputs to make it ATX compatible, a complete harness of cables AND is smaller.

    Correction: PicoPSUs are SMPS. The only alternative would be a linear regulator, which they are most definitely not. The difference is they are DC-DC, rather than isolated AC-DC.

    Might be an alternative for the Sea Sonic 300W. the sea sonic gets loud as soon as the fan is up and running.

    There is one Pico Combo I know which is not an SMPS. It's a HD Plex.

    Full gamut of DC outputs? I see 1 sata and 1 molex +1 floppy. That's it.
    Some PicoPSUs do come with an extra plug that has molex and sata.

    FSP350-701UH

    There are two types of HDPlex PSUs. But at 100W it's easy to make a fanless PSU.
    One of them is a big massive power hungry linear PSU and the other is a picopsu. The third type is an open frame power supply, I just got an authentic delta open frame PSU the other day and despite being 100W the components used are rather small

    What I mean is taking AC and converting it into +12VDC in addition to +3.3V, +5V, -12V.....

    PicoPSUs regulate +10V~+19V into other DC voltages, but by not having to convert from AC you're taking half the hardware out of the equation.

    Not with 240W capability. I've yet to see a 240W brick this small. Thinner, yes. But total area?
