I tried one of these (5V) to power a hub with a single stick+fan. With rare exception, couldn't get the stick to mine.
http://www.meanwell.com/mw_search/SP-150/SP-150-spec.pdfWent back to the 3 amp wort that came with the the hub and everything fired up hungrily.
Is there something about this power supply's specs that stand out as to why it 'may be inappropriate' for this purpose?
What specs are on the wall wort?
If it is 3amps. And 12 volts you need a 12 volt psu not a 5.
The hub comes with a 5 volt 3 amp wall wart. Measured no load DC output voltage 5.23.
The meanwell PS is 5 volts 30 amps. Measured no load DC output voltage 5.35.
Seems the hub just doesn't like the power supply. I'll keep playing with it.
Did you use a barrel plug or solder wires to the hub? If you used a plug, could it be the wrong size? Like using a 2.5MM on a 2.1MMplug.
Then again, if the hub has some type of over voltage protection, it may see the 30 amps as being to much over 3 amps and kick in the protection.
