Sorry but it won't be 400W or more, if you find one claiming
it is, it will basically be a lie from the labeler.
A mATX supply is worth about 200W, "maybe" some now are
worth 250-300W if enough of that current is devoted to the
12V rail, but we don't know if you need a lot of 12V current
or not.
With a mATX supply it is more important than ever to buy the
right one, an older system needing more 5V current can't use
a new mATX supply delivering mostly 12V current and
vice-versa, unless the system was very low powered to begin
with, which doesn't seem to be the case since you're asking
about 400W.

Since a decent 400W supply costs closer to $50, and IF a
mATX existed that could do 400W, it would cost even more for
the high spec parts to make that happen, it would cost
closer to $75 perhaps, if all else were equal but all else
isn't equal- such a supply would have a very limited
marketability so the price would go up even more, past $100.
$25 is just unrealistic.
To determine if what you want to do is viable, or what PSU
might meet your needs, it might help to post more info about
what you're trying to power. Generally speaking your best
bet for a mATX is to just buy a know quality brand's
offering, instead of a generic, and then compare it's rated
12V & 5V current against the requirements of your specific
parts. |
