I just bought a Pico power supply to power my mother board. But I am unsure what kind of adapter I need that will plug into the wall. I would like to find a cheaper alternative then the ones listed on their site. The 8.5A adapter is selling for $35. I see plenty of 19V ones on ebay that sell for cheap. But the pico power supply needs a 12V input source. Would the power supply be able to reduce to 19V to only 12V to the motherboard?

Would something like this work? Ebay link

  • 19V will probably kill your power supply. – W5VO Jul 24 '12 at 01:33

  • The downvote was probably due to the fact that this is not really an electronics design problem, more a item specific "technical support" question. To answer the question though: if it says it needs 12V, then 19V won't do - use 12V. – Oli Glaser Jul 24 '12 at 03:41

The manual says:

Input Requirements: 12V regulated, min=2A, max=10A (load dependent). Over-voltage shutdown will occur at ~13-13.5V.

So 19 V may not kill it, but if not will shut the power supply down. Use a 12 V regulated input as required.
