PicoPSU power supply. I'm tired of the giant power supplies the size of cinder blocks. I was thinking of moving towards something in a smaller form factor. I'm using an unmodded makerbot motherboard (RepRap 1.2), so it requires an ATX power supply. I stumbled across this little thing: [www.silentpcreview.com] The PicoPSU is so adorable! But do you guys know if it's powerful enough to run a Mendel? https://reprap.org/forum/read.php?4,42913,42913#msg-42913 Fri, 10 Jul 2026 22:42:29 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,42913,43377#msg-43377 Re: PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,43377#msg-43377
Basically the PicoPSU allows for a drop in replacement of a standard ATX power supply.
There are small ATX alternatives, but i didnt feel they were small enough. It was cheap on ebay and i got the additional transformer for free from a friend, so the price ended up being comparable to buying a standard ATX power supply. (~$30)]]> CidVilas Reprappers Wed, 21 Apr 2010 12:26:40 -0400 https://reprap.org/forum/read.php?4,42913,43368#msg-43368 Re: PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,43368#msg-43368 nophead Reprappers Wed, 21 Apr 2010 10:04:41 -0400 https://reprap.org/forum/read.php?4,42913,43366#msg-43366 Re: PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,43366#msg-43366

Standard ATX power supplies are only "big" because that is the size that IBM used in the old IBM-PC/AT back in the 1980's. If you want a smaller power supply, look for a "Micro ATX" supply. It has the same ATX connector and can be much smaller since they aren't expected to fit the existing holes of an ATX case.]]> JohnWasser Reprappers Mon, 19 Apr 2010 13:31:14 -0400 https://reprap.org/forum/read.php?4,42913,42971#msg-42971 Re: PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,42971#msg-42971
2. Another problem with that would be the need for extension cables and splitters for the power leads.

3. While its quiet and compact, its exposed and pricey.

You would have to buy a regular tranformer on top of the $50 for this distribution block.

As has been said only 12v is used, so its only 12v distribution, the board is effectively a filter for the 12v supply with 5v and 3.3v Vregs.

It can handle the current for a Mendel, but IMO its not worth the expense.]]> annodomini2 Reprappers Mon, 19 Apr 2010 07:04:31 -0400 https://reprap.org/forum/read.php?4,42913,42920#msg-42920 Re: PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,42920#msg-42920 Trevor Reprappers Sun, 18 Apr 2010 23:33:47 -0400 https://reprap.org/forum/read.php?4,42913,42913#msg-42913 PicoPSU power supply. https://reprap.org/forum/read.php?4,42913,42913#msg-42913
