    does anyone have any experience of what can be done to quieten one of these?

    Does anyone know if a 'picoPSU-160-XT 12v 160W' will fit, and would be enough to power a few HDs and DVD writer?

    Or which 120mm fan spins fast enough to keep the bios happy but remains as quiet as possible?

    Or whether the vented PCI plates will fit?

    thanks

    The standard PSU is only 150W and can power a fully configured one (In reality the fully loaded power draw should only be 75W or so), so in terms of wattage a 160W will be fine. You'll need to ensure there's enough clearance for the extra PCB and cables that come attached to a Pico PSU though. You'll also have to consider the implications of connecting 4 hard disks and an optical drive from a single molex and single SATA connection. You'll also need to find a spot where you can connect the power socket for the Pico PSU but with the standard PSU removed there should be plenty of space - could probably even put it in a PCI bracket if they're wide enough.

    It's not a proper server so the BIOS is no more intelligent than a desktop PC so you shouldn't have an issue. If you have the server already you could also check the BIOS to see if there's options for disabling fan failure warnings.

    You'll need to get low profile vented PCI plates (if there is such a thing), but they won't make a huge difference.

    thanks for the reply

    there's a suggestion on other articles elsewhere that the Pico PSU should fit but those are lower wattage ones - do they differ in size dependent on wattage?
    apparently "primary cooling fan is a 4-pin PWM type with a pin-pattern that is non-standard" which causes difficulties and apparently the fan speed is monitored and the BIOS prevents booting if insufficient speed. A "Scythe fan at 550 RPM" is apparently fine


    thanks

    You could always bypass the motherboard and just jack it directly into the PSU, though as before you'll need to be aware that you've only got a single molex on a PicoPSU.

    I've no idea whether the wattage alters the size of the PSU, it's going to be a case of getting the thing and checking how much space is over the 24-pin socket on the motherboard and then I'm sure Kustom will be able to tell you how big the PSU you're looking at is.
