This thread will serve to post all relative information for the DSATX 220 watt Automotive Power Supply and the Brainstem.
This thread is not to be used for troubleshooting, but rather for FAQ type responses.
If you have a motherboard that expects the -5 volt signal instead of the +5 volt signal, and you build the reverse polarity circuit (cable) as shown here , you may end up with the power supply starting and then stopping a few seconds later. This is caused by the cable you created was plugged in incorrectly. The single wire goes to the MB power On pin which is the pin that is closer to the center of the board. The other cable then plugs into your motherboard.
Ineffigy, glad it worked for you. ;) I tried every combination x 10 and it kept having the boot issue.

less than $8 for parts.
I bought a refurbished DSATX from you guys. I didn't expect to need to build the cables, but apparently you can't get them. The local PC shop, was kind enough to give (gasp - give!) me two burned out ac-power supplies from which I could salvage all the connectors and cables to make my own.
If you are going to build your own cable, it pays to keep a clear head. There are a lot of wires - easy to get confused. I used crimp connectors and heat-shrink tubing.
I installed the DSATX on standoffs in the box of one of the dead ac power supplies the pc dealer gave me. I removed the fan from the box, becaue my 3u case has 3 fans. box is installed in front of case and fans draw all air for system through DSATX power supply box, then over drives and MB, then out the back.
IT WORKS GREAT. I'm using a bit more than 1/2 the amps the inverter and old ac ps used. Typically 65 watts/ compared to 120-130. On our boat,this is critical because old setup was second biggest battery sucker after refrigerator. We have eight 6 volt golf cart batteries wired for 12 volts and we have to run genset to recharge them.

I used the jumper to thwart the board's many options and it turns on and off just like a conventional PC -
what a great product. :)
In the manual it says:
t3 = Time between Computer Shutdown Pulse and +5V Standby OFF. Default = 90s Max, 2s Min
That cant be right, can it?
I cant set the time to 30 mins or above?
Why would you want to wait 30m or longer for your PC to start shutting down?
Not the shutdown delay.
I am talking about the delay until the +5V rail is shut off, aka no more power for the RAM to allow quick resume from sleep. I dont want to use hibernation all the time, especially if I just leave the car for a few mins.
