Hi everyone, I have a ECM40UT31 power board, replace the old PSU. The install is finished. I've checked the new PSU outputs are +12.44/-12.20 /5.03v when I set the 5.0v ouput up to 5.2v the +12.44 goes up to +12.80v. Is +12.8v output too high? The Wiki says: Plug it back and power-up to test it. The new PSU comes pre-set at 5.0V and Meridian recommend re-setting this to 5.2V, although this doesn't seems critical. Apparently, the adjustment to 5.2V is only possible with the XP power supply. If you have a UMEC power supply - as most M processors older than 2 1/2 years - there is no adjustment.

I doubt it. That's only a few percent out of perfect-spec. When I did mine, it was a bit high as well.

I think it was St Edd who noted a couple of months ago that G series should be 5.0V, it was only the 800 series which needed 5.2V?
Cheers

Thanks to wiki.
i want to say,yourself to replace the power supply is danger,
it can damage the machine,to replace it need professional knowledge.
I don't know now, it set to 5.03v or 5.2v.

I have changed three G-Series power supplies now (not counting the ones I swapped back again after adjusting them). I always set them to around 5.2 to 5.4 V otherwise they show some issues like switching themselves off.
It's not difficult just be careful that all the output pins are the correct orientation.

Agree with Neil, 5.2 makes a difference.

Hi VirusKiller,
Then I try to set 5.1V, but the +12V output goes up, do I not need to consider the influence caused by it?
In my estimation, if set to 5.1V the +12V will be up to +12.62V
Is the output up to +12.62V is too high?

I really don't know Jack - I'd contact Meridian support on this one.
