24pin DC ATX PSU 12V DC Input DC 12V 150 watt Pico PSU ATX High Mini-ITX Power Supply with Adapter Board ATX Switch PSU Car Auto for Computer Mainboard and car/Motorcycle

If you're like me and need to test motherboards that don't require a lot of power draw, this is an excellent power supply for your workbench. This will power most motherboards with a few peripherals. It's small, has extremely clean and accurate power delivery and can be powered from my bench power supply or from a wall adapter. Personally, I power it from my bench power supply. This was a great purchase that I've recommended to friends.

I purchased this to build a new power-supply for my 31 year-old Macintosh LC III. I specifically selected this unit because it has no electrolytic capacitors, whereas several other Pico supplies do. You see, the very reason I had to purchase this power supply is because, after 31 years, the electrolytic capacitors in my Mac's old one had exploded and leaked electrolyte all over the place. To the extent possible, I want to limit my antique electronics to use tantalum capacitors, so they will outlive me, and last a lifetime, as they almost already have.

Great so far BUT the input wires cause a lot of voltage drop. I was seeing 10.3v at the motherboard running prime95 with a 65w cpu and the wires were hot after only a couple minutes. I replaced the 16-18awg wires with true 14awg by soldering and heat shrinking to the original connectors. With this mod its perfect, maintaining 11.8v, well within ATX specs. Engineer by trade.

Seems decently built but has a major flaw I didnt notice until after in-hand. The power and motherboard cables connect to back side of the pcb and point towards RAM on typical ITX motherboard with two RAM slots to the right of the socket. This means that any heatsinked ram is almost certainly too tall for cables to clear without pinching. Even with bare modules the power cable is slightly pinched up by the memory. Ive had a few different model of picos in the past and this seems to be on the higher end of build quailty. If you have a board with memory slots flanking the socket or something with so-dimm this could be a good option. Or if you arent concerned with slight pinching bare ram could work. I'll probably hold on to it at this price and have it if I ever need it.

Its working so far, I am using it with this itx motherboard that is really low powered, the power supply I am using it a 6 amp and it seems to feed the base clock on the processor. CPU doesn't boost up to its max and I believe is due to the power brick so I bought a new power brick , 10 amps since that would be more than enough for this low powered board. I happy with this ATX psu let see how long does it last.. The build is being used as Opnsense Firewall.. Regards!
