Default Server power supplies, any good for audio?

Hi Guys,

I got involved with these things when needing a strong PS for running hi amp battery chargers. I couldn't help but wonder if they would have a use in audio. They are relatively inexpensive for the amount of power they produce so I thought I would ask. I'll list this one as an example, but there are several that are similar. This one I am familiar with an it puts out 47A at 12.6VDC.

So what are the pros and cons of using such a power supply for audio?

Thanks, Terry

I've got a bunch of server supplies that LOOK like they'd work really well. Problem is getting them to turn on... The pinouts and ways to set them to operate seem to be a deep, dark secret.

Go to this thread and see if your PS is in there. They have a lot of Server power supplies covered with instructions of how to turn them on. it is actually full of links to threads about each given PS.

Hope this helps.

I've got two SUN BLADE 2000 power supplies made by Sony Japan and I bet they are real good. (Sun / 300-1357 / Sony 670 Watt Power Supply for Sun Blade 1000, Sun Blade 2000 and Sun Ultra 80 -- Sun Parts). I surprised when open this PSU: very thick cable, all see very high quality.
Just wonder if it is good for audio application? Anyone got any suggestion?

Thanks for the thread.

Searching... So far, I mostly find the computer PSU is for powering car amp in home usage or for sub.

They put out Regulated DC and pretty good current. There is also a voltage share pin so they will match each other. I know they are only 12.6V but at 50 amps they should be able to drive a healthy load. I'm interested to hear if anyone has tried them for audio amp usage.

They appear to be ideal for powering 12V car amps at home. That would be the most sensible way to use them.

I knew they would do that. I wondered about using them as a replacement for the normal transformer/CRC setup. I have a few that are set up for 24V, 47A power to run high powered battery chargers. It could easily be split at a +/- 12.6V 600W power supply.

The voltages just don't seem useful unless you happen to be driving very low impedances, like an array of speakers or, perhaps a servo motor. Stacking a bunch of them would be OK for the test bench, but not an elegant way to power amps in the living room if it takes 8 to 12 of them.

What's the ripple like?
