    LEX 12v Dc Power Supply CHEAP but good?

    Hi i just discovered a power supply available from http://linitx.com/shop/ very cheaply only 21 pounds!
    has anyone tried using this before?
    any success?
    would it work well with car voltage?
    could it support 80gig normal hdd and normal dvd drive?
    all feedback would be greatly appreciated.
    cheers!

    can you post a link to the item itself?

    Almost certainly the +12V rail will be unregulated, which means you'll need to post-regulate it, which is not a trivial task if you want to run it with the engine shut off.

    There are 2 recent topics dealing with this exact problem, check out

    If anyone knows where to find cheap DC-DC AT PSUs, speak now

    and scroll down to my last post, you'll see what needs to be done.

    If you mena the ATX module:

    12V DC in (11.4V to 12.6V) to ATX power connector PG/3.3V/+5V/+12V/-12V.


    I'd hazard a guesstimate that it is unlikely to be reg'd o nthe 12V rail, as it's such a narrow input voltage range and the external brick is likely to be pretty well reg'd anyway.

    Exactly, why bother regulating twice when you can regulate the +12V in the brick, and then just do the rest inside the case PSU (since the entire purpose is to make a small case PSU)...

    From what we've seen they are NOT regulated on the +12V rail internally, they expect the input to be regulated already.
