New Mpegbox Power Supply
Hey All,

Your prayers are about to be answered.


Here your looking at the new DSATX Durawatt power supply from Mpegbox.com

This power supply has the following specs:

8-16 volts in

12V @ 11 Amps
5V @ 11 Amps
3.3V @ 10 Amps
5VSB @ 1.5 Amps
-12V @ 0.15 Amps

I am going to call it a 220 watt DC-DC power supply.

Here it is powering a P4 motherboard and hard drive with an 8 volt input:


Here is the P4 motherboard on the BIOS and my Main PC on the right, it is connected to the power supply with hyper terminal:


Here is what the power supply is currently spitting out of the serial port every 100 ms:


Basically this is as follows
Temp in Degrees C : Input voltage : 12 volt rail : 5Volt rail : 3.3Volt Rail : Pot1 : Pot2 and the YYYN means all the rails are within 5% except for the input which is 7.14 volts (and powering a P4 by the way...)


This power supply is very very efficient, has a very beefy 12 volt rail, and will have by far the best serial port diagnostic and programmable shutdown controller on the market.

Any takers? :-)


-Jeff

damn that thing is tiny! how the hell did you make it that small and 220W? Will it need any active cooling?

If you only use it for 100 watts you don't need a fan or anything. If your going to go over that, a fan is going to be needed. It didn't even get warm powering my 2 gig p4. It was only pulling about 90 watts in idel mode..

It has heatsinking in the board. I am going to design a case for it. That will have a 40mm Fan, it is >95% efficient. None of the parts generate more than 1.5watts of heat.
