One or two power supply for 10 computers...

[Rovetto Stefan]

Greetings,
I like to use 10 computers with motherboards only without any case. Now to
plug 10 AC-DC power supply (220V) on this motherboards would be stupid. Does
exist a special "big" AC-DC power supply with 10 "cables" for multiple
computer motherboards?

Thanks in advanced.

Balancing the power to each MB would be precarious at best in my
experience. The other big problem that you will have w/o cases is
cooling. You have to have a good amount of air moving over the
processor(s) in order to pull the heat from the sinks. The most I have
done this with is 5 CPUs, and I had one fan pulling from overhead.

As for power, using a micro supply will power the board(s) and a HD
without too much trouble at 150W. look here
http://www.allelectronics.com/index.html and there are many for cheap.

The cabling to power each MB (and drive) is such a mess, that separate
supplies are the much better way to go.

Depending on what you are tryign to do, you could ditch the regular
desktop motherboards and go with something like a compactPCI chassis or
a "blade" enclosure.

You will pay a little more, but the system will be engineered to work
correctly.

Just my $0.02.

Given how inexpensive PC power supplies are, there's no way you'd be able to
find one 'super' power supply for 10 PCs for less than just buying 10
individuals ones. Even if you could find one (I mean, if you have enough
money, power supplies are very much commodities and someone would be willing
to build them for you), it probably wouldn't be all that much smaller than
the 10 individual ones.

There are at least two serious flaws with this, besides the obvious
distribution impedance problem.
1)A single fault can take down the whole system.
2)Current limits are set to reduce damage from overcurrent.
Your big mother supply will have 10X the current limit.
Anything that goes/gets accidentally shorted will be vaporized
along with much of whatever exists between the short and the power supply.
