2 Power Supplys to 6 in 1 - Serial VS Parallel Wiring.
Savannan:
Hello all....
Some of you may know that I'm in the middle of making a Multi-MK arcade system...
http://forum.arcadecontrols.com/index.php?topic=114119.0 <-Scroll Down
I got my 6 in 1 Jamma Switcher..but when I use those cheap ass Jamma Extenders from the 6 in 1 to the PCB I have issues.
I checked out this thread on classic MK (and posted my findings)

The Jap Jamma Extenders will not carry the current to any of my PCB's So I turned up the voltage on my stock MK2 power supply. I'm still having problems with current using the auxillary sound board on MK2. Once the game played anykind of sound, the PCB resets. So I figure it's still not getting enuff power to the PCB/Sound Board.
Im goin to buy a 600w P/S.

Will this P/S be enough for what I need?
If not....What about this senerio....
Purchase 2 Power Supply's...wiring up each power supply to MAIN jamma harness...and connect it to the 6 in 1.
Will this still be 12v, 5v, -5v but with more current or will it be 24v, 10v, -10v ???? Kinda like jumpstarting a car...
I know the longer/thinner the wire the more of a current drop you have.
Any help would be appriciative...

If you put the power in series you will blow your boards. You cannot put 10V where 5V is the voltage etc etc. If your extenders are giving you a problem then you maybe able to improve on them by increasing the size of the wires carrying the 5V 12V and GND. A better way to increase the amperage of your PS is to buy a higher rated supply. 2 switching power supplies put in parallel stand a good chance of fighting each other.
Savannan:
Hi,
Ohh no..I know putting 10v in a 5v situation will blow something....
Just wondered how I could increase the current to the PCB's. I thought that by adding another power supply would increase the current. I did put larger gauge wire on the power/ground pinouts on the extender already...I did this before I even got my 6 in 1...so the problem still exists...
By buying that P/S that I listed above....Is that a better choice all around than my stock MK2 one?]

BobA:
A 600 W ps will provide alot more current then your existing MK2 supply.
Savannan:
Thanks Bob. I'll give that a go. :applaud:
