I has to be quiet

[George Hester]

I'm looking for a Power supply 500W or more. But the thing has to be quiet.
What I am finding is that many Power Supplies seem to be using Marketing
hype such as, "580W-Max Silent ATX Power Supply." What I would like to know
is what is the term that is used for Power Supplies which are quiet? Is it
called Noise Filter? Is that the technical name for it?

OK that is more than I originally had to go on. But see I am looking for
the technical name for Power Supplies of this type. To say a Power Supply
is quiet or silent may not mean much since larger Power Supplies are noisy
and to say a Power Supply is quiet may mean only that it is more quiet than
other Power Supples of this type. So that is why I need the technical term
that is used so than I can be sure that I am getting what I expect. I think
it is called "Noise Killer" or "Noise Filter" not sure. EMC also???

George, are you running some sort of business? Restoring machines for
some reason?

Some guys restore cars.

 

[George Hester]

No Dan. I buy stuff REALLY cheap at eBay and make them work. Then I use
them. It's a hobby I guess. Some day I want to build my own machine from
the bottom up but the only way I am going to learn it is to have lots of
stuff so I know what they are; how they go together; and what the right
stuff should be.

I dont believe there is any 'genuine' tech.name for a quiet pwr supply.
If you visit the web sites of the specialist pwr supply manu. they may have
exact details of 'sound' output

 

[Dan Seur]

George, thanx fror slaking my curiosity about the nature & volume of
your traffic. It's a great hobby.

It strikes me that buying parts REALLY cheap thru ebay may give you a
chance to experience a REALLY wide range of hardware problems!

 

[George Hester]

I know doesn't that sound like fun? Find where the problems are then we
know first hand what to avoid. Almost like some Operating Systems and their
affiliated security updates I know.

Each manufacturer will call their "quiet" power supplies out
differently. Hush, Silent, Quiet, Whisper etc. Search on any of those or
visit a web site for "Silent PC's" and read up on their recommendations.

That'll work thanks Colon.

I like their stuff, but I also recommend http://www.quietpc.com
However, their PSU line stops at about 450 W. The quiet units
from PC-PowerCooling don't go much higher, either.

You might be able to work around this by, for example, moving
some or all of the hard drives and optical drives to a separate
enclosure with its own power supply.

As well, if you have lots of hard drives, using a RAID controller
that staggers the spin-ups of the drives can dramatically reduce
your power requirements. Nothing that says you have to use the
RAID capabilities of the card. Hard drives use a lot more power
when they spin up from rest, so staggering the spin ups can
reduce the power requirements of a 5 drive array by 80 to 120 W.

If you are up to fiddling with the wires a bit, there is also
nothing stopping you from putting two PSUs in one computer. You
could, for example, have one PSU for the drives and one for
everything else.

I was thinking of doing that. Trouble is I can't close up the box if I do.
And I'd have to rest the 2nd PSU on top of the first. So I'll just try some
"Quiet" ones on eBay I saw one for $5.99 said quiet 500W but didn't try it.
I want to make sure I get one that is close to specs which is what I think
the True? ones are.
