    Shuttle SN68PT PSU problem

    When I try to switch my PC on, nothing happens. I have to disconnect the mains cable, wait for the lights on my USB hub to go out, plug in again - and it starts fine.

    The USB lights bit is just a visual cue. The same happens when the hub is not fitted.

    Latest BIOS is installed.

    It seems to me this is a PSU problem but before I splash out I wondered if anyone else had encountered this problem. It wouldn't be the first time I've had to replace a Shuttle PSU.

    Many thanks.

    THE USB light will go out when the caps in the PSU are discharged. Are you putting the system to standby or shutting it down?

    When system is shut down and I try to restart, it won't. As above, disconnected mains cable from back of case, waited a few seconds, reconnect - and it starts up.

    I've been searching other forums and it seems the PSU may be underpowered and a 300W version solves the problem. If that is the case, it's not a good design.

    Many thanks for replying.

    Oh I was having a problem with my system resuming from standby which was also solved by pulling the plug, turned out to be a Windows issue which still hasn't been patched! Do you have another PSU you could test with?

    Sorry, no spare PSU.

    To cap it all, various suppliers are telling me there is no compatible Shuttle PSU for the now obsolete PC40 (in the PC I have) and the PC50 (which Shuttle say was the PC40 replacement).

    They say the PC60 is meant to replace the PC50, but only in certain Shuttle cases - and not the SN68. Hmmm. No more Shuttles for me I think.

    Yeah that's the problem with proprietary form factors, you're relying on the MFR to continue support for replacements/upgrades etc. You could always move everything to a micro-ATX case, I'm not 100% sure but I think everything (apart from the PSU) would be compatible and you could use a standard ATX PSU then.

    Re: Shuttle SN68PT PSU problem

    The PC40 uses standard ATX connectors so any 1U PSU with the same dimensions should work in theory as long as they have split ATX power connectors. I have used the PC40 to power up a mini ITX motherboard so any similar PSU should be able to power up the Shuttle motherboard in your system IMHO.

    Here are the dimensions of the PC40:

    These units should work AFAIK:

    http://linitx.com/viewproduct.php?prodid=12301

    http://linitx.com/viewproduct.php?prodid=12538

    They both have 20 pin and 4 pin ATX power connectors.

    In theory the PC60 should also work fine as long as it has the same ATX power connectors as the PC40.
