Hello,
Did anybody tried to open-up this Sony APS-172 power supply? I do not succeed to do open it as I am afraid of breaking something if I force too much. It seems to me this device was designed not to be opended at all!!!
I want to extract the fan cables in order to install an external speed variator. So if someones if knows how to open and dismantle this beast, some guidance would be most welcomed.
Thanks
Regards
Peter

Ah, forget what the expert forum members like notfuzzy and quint say over and over. You'll totally get 2880W out of the 12V rail. Hook it all up and go! (away)... 
Actually, it's worse than that - I worked for Qualidyne as a production tech for a while, building and testing high-amperage supplies for IBM Mainframes (this was back in the 1980s, when a 5 VDC 100 amp or thereabouts switching power supply was almost the same size as many current ATX mini-tower cases and the bloody output supply rails on the thing were ballpark 1 inch wide quarter-inch or so thick BUS BARS)....

In that case i can use power 12v to peek up 2800w, like that yes or no sir 
How many ways do we have to say "Not only no, but HELL NO"?
The +12V output is NOT rated for 2800 watts, it's rated for 1335 watts MAX and THAT IS ALL YOU CAN PULL OUT OF IT ON +12V.
So From all commend get i think , i can use "APs-172" 12v full to 2800w ??
For the 3rd time - NO!The nameplate states maximum power available for 12V out of that supply is 1,335W and that is all it will provide @12vdc. No higher peak allowed. PERIOD.
Not by itself. After 20% margin, you'll have a little more than 1kW to use on 12V.
The bulk of the rest of the power would be on the 50V rail, which you'll need DC/DC converters to turn into another 12V rail. And then you might as well just buy another 12V PSU.
A 50V (or 48V) PSU is very useful for DIY audio projects. A high powered audio amplifier and a Bitcoin miner in the same box would be an odd idea, though. A gaming PC with a built in high powered audio amplifier, however, would make sense. Because it is a -50V rail, you'll have some issues with level shifting (hint: S/PDIF fiber would work nicely with the least chance of breaking stuff), but then you'll have the option of powering the amplifier from 62V to get a bit more power.
If you already have the PSU and aren't looking to do that kind of project, you'll probably be best off selling it to someone who is, then buying PSUs that actually fit your uses better.

50V is what PoE (Power over Ethernet) runs at for enterprise use. One common standard is 0.35A per port, so that PSU can be used in a switch with 80 powered ports.
That, unfortunately, is not very useful for miners. (It would be very useful for building a nice gaming PC with a super nice audio amplifier built in, but that's another story...) You could use a DC/DC converter to turn it into another 12V rail, but that's yet another added cost. Cheaper to just buy PSUs that are designed to run 12V only loads.

-50 volts at 28 amps is 1400 watts, or almost half the TOTAL rated power output of that power supply.
That's NOT a standard computer power supply - like NotFuzzyWarm I'm inclined to believe it was intended for use in landline telecom equipment.

You misunderstand.
TOTAL power including the 3.3V @12.1A and -50V @28A outputs is 2880W but as stated on the nameplate the 12V output is only good for 1,335W. Just because you do not use the 3.3 and -50V outputs does not mean you can pull more from the 12V rails.
With that high current negative 50V output I assume the supply was originally for telecom systems. This is why the IBM server PSU's are so popular - their main power output is only 12vdc and nothing else.

Hi everybody, I need to know about the power output this "sony APS-172"
I use 12v for bitcoin mining, but's the plate detail 12v /113.3a =1335w
Isn't get up 2800w?, or i misunderstand
Expand me please
Thank you sir
