PicoPSU for CPS2

[djpweb]

Hello all,

I'm preparing my todo list to consolized a CPS2 but the Power Supply question is still unclear to me. I was about to get a PicoPSU to power the board :
http://www.mini-box.com/picoPSU-160-XT

But the manual doesn't give any info on the -5V spec (Pins 5/E on jamma)...
On some ATX 1 (20pins) pinout the -5V is clearly identified but it's not that clear for ATX 2 (24pins).

What am I missing ?
Does the CPS2 need the -5V to be connected (it seems not all boards need it) ?
Any recommandation ?

Thanks !

A Pico works great with CPS2, -5V isn't supplied from the Pico nor is it needed for CPS2.

Awesome, thanks !

Just to check: Which picoPSU model are you using? Would a 90 W model work? I'm looking for a portable way (for LAN parties and such) to power my CPS2 setup with a DS multi and CPS2AV via RGB's CPS2IOI.

That will do nicely. It handles up to 6 Amp on the +5V line with a peak of 7 Amp, and has overload protection.

For future reference, I can confirm that the picoPSU-90 works fine with this 12 V/5 A/60 W AC adapter. I'm measuring a stable 5.04 V/11.9 V on the CPS2IOI's JAMMA connector.
