What's new
I've just got hold of one of these too. Hoping it solves my N2 problems! At the very least I'm hoping for less stress on the Naomi's!

Whilst it hasn't fixed my RAM problems - I am now getting the error much more consistently!

I've adjusted the voltages so it's doing:
3.32
5.01

I have a thermaltake smart series 500w psu, would this work with my naomi 2 with non-net dimm?
 
just opened up my qp-150 and am having difficulty adjusting it. admittedly i am a noob.

best i can do seems to be 5v at 5.45 which results in 3v being 3.25 (without load)

i assume this will drop when connected, but does this sound about right?

otherwise when exactly at 5v without load, i get 3.3v at 3.04
 
It has separate adjustments for +5V (V1) and +3.3V (V2).

Also, don't try to make adjustments without a load connected. Mean Wells do not work correctly without a load.

Gotcha, just didn't want to connect it and have it read high. I can't seem to adjust the +3.3v separately, it will only increase when I increase the 5v. Turning the pot for 3.3v doesn't seem to anything but lower or increase value by 0.01.
 
That's because you don't have a load on the +3.3V rail.
 
X/ ahaha

thanks nem, i will give it a go underload and see how i go. appreciate you taking the time to point that out to me, like i said i am a noob :thumbsup:

This goes for basically all arcade / switch mode power supplies. There is a minimum required load for most supplies like this to operate as you said.

Friend made this. Has all 3 voltages on a different PSU which makes it great for troubleshooting power problems. Also has a place to populate for the gdrom drive power, but I never use that. Costs about $75 to make

Did he make that PCB with the voltage meter (3) and I/O rocker switch?
 
Is he willing to share KICAD/gerber files or modify it?
