1106 DC to DC ATX PSU 12V 300W Pico ATX Switch PSU 24pin MINI ITX PC Power Supply for Computer

This thing works perfectly. Using it with this power supply (https://www.amazon.com/gp/product/B074GGMD5J) on my media computer for a totally silent build! Working flawlessly for over 4 months now. Updated: I now own 2 of these and they are both working perfectly. One is in my son's i3 for a silent build in his room, one is in an i7 silent build in my bedroom. These things are great! Buying a third to silence the computer in our kitchen. It's liberating to rip out a noisy power supply and put in this tiny thing for blissful silence! Other thoughts: This is a 300 Watt power supply. Be smart and make sure you're tracking your power budget! It easily handles my 95Watt i7 3770k, 100Watt motherboard, 5Watt processor cooler, dual Ethernet (80' runs), and a few low power USBs. And I ask a lot of my system. BUT, I use the onboard Intel Video!!! This is a perfect power supply for a silent build if you use the processor's onboard video, but don't go putting in a video card that pulls 500 Watts! Do a little homework and some simple Math!

The 160 watt PicoPSU I was using was showing signs of failure as I was seeing random rebooting when under load. So I went with this larger but more powerful PSU and it is working great! I found some space to mount it under the hard drives but I needed to drill and mount two stand offs to secure the unit as well as allow some airflow underneath.

How does something this small deliver 300W? By not having to produce the 12v from which most of the computer's power is drawn, so all it has to do is switch it on and off, plus regulate it down for the 5v and 3.3v busses which require much less current. The problem is that the included wiring to the 12v bulk supply isn't robust enough to handle the current at higher power levels without excessive voltage drop. When I tested the supply with a Meanwell bulk supply, there was over a volt of drop from the bulk supply to the motherboard due to the resistance in the wiring and connectors when the computer was running at peak power of about 150W, and that's not good. I replaced the 12v input connector with 12ga soldered-in wires, and the barrel connector with Anderson PowerPole 20A connectors, two pairs in parallel. With the same type of wiring to the bulk supply, the voltage drop was reduced to less than a tenth of a volt at peak power. That said, the modified supply has been running pretty much 24/7 for the last 3+ months without any trouble with the CPU making regular full-power runs.

I am using it for crypto mining, i am currently powering 5 CPU Mining rig using this. One thing I didn’t feel comfortable, the original 12v input wire to the board were too thin, it was getting too hot for my liking, fire hazard. The original wire, copper gauge was 24 AWG (3rd image, 2 red and 2 blk wire connector, is the original) and I upgraded them to 16 AWG (new connector that is on the pico board, red, white, green and black wire). 2-3 wires of the original is equal to one of the 16AWG wire I replaced. Now works perfect. Powering all of them with a Server PSU and a breakout board(SEE VIDEO).

I dabble in CPU mining. My little farm had grown to the point where I had ATX power supplies all over the place and they took up as much room as the motherboard itself. These Pico PSUs run off 12V so there's multiple ways to power them. Using a 1200W server PSU and a breakout board you can power 1 to about 8 CPU mining rigs, depending upon how much wattage you are drawing per rig. In the attached pic you can see I have 8 rigs in a small footprint. I used to have only 4 in this space b/c the ATX PSU took up half a shelf. I recommend these slightly more expensive 300W Pico PSUs over the cheaper 200/250 watt versions. More PSU headroom is always a good idea. Been running these for about a month now, no issues at all. Highly recommended.

Works great with a portable ITX computer I built. Would definitely recommend if you're needing an alternative power source for computer.

well. first off if your buying this most likely u want to run a computer off a battery like I am, 13volt dont work. used a voltage regulator. to keep the volts to 12volt. and mine defective, on and off when u but a load on it and this is the 300watt version. they need to have a regulator built into in. cause u could have a 12 volt power supply from the wall but if its higher voltage or to low for it, it wont do nothing. this thing is to picky and not reliable for a 12volt battery, the other version I have had was the 250 watt that worked for 4 days, but I didn't realized that the battery was charging and the volts was 14v and the thing wouldn't work at that voltage! but I didn't know this so thought it was deflective so I did a return.NO instructions came with it. so I have been learn on my own this this stuff and now a few of you out there. u would think there would be more than 1 manufacture for this type of thing also there would be less waste if they had instructions with it. and a voltage regulator built in and there would be less waste and returns!!

Needed more power for an upcoming video card addition so I picked this up to replace a 19.5v 90 watt unit. Would be nice if this unit also took a 19.5v laptop type bricks because there's not a lot of new options for high amperage 12 volt power bricks. Ordered a used 240 watt Dell DA-2 (google for guide), 5.5mm x 2.5mm barrel adapter, and a 6 pin to dual 8-pin PCIe adapter (barrel to this Pico unit, and 8 pin to the GPU) to rig up a suitable power source. It was around $25 total, but requires some electrical know how. Should be plenty for a 125 watt GPU, and 65 watt CPU (estimates include undervolting, but I expect 100-175 watt loads while gaming). This unit comes nicely packaged in a basic little brown box with power unit, and several sleaved cables. One of the yellow power cables for the legacy hardware (floppy drive I think) was not connected, but I'd never use it. Set up was easy as it slid into the old units spot. The 5.5mm x 2.5mm barrel power receptacle broke off after being mounted, but it still works in testing. Might have to solder a new one on later. The blue LED light is quite bright. Will probably cover that up as you can see it through the mesh side. All in all, it's fine so far. Be aware that you need a 12 volt power adapter with enough power for your usage. Google power consumption for your parts to get exact numbers, and then search how to undervolt your GPU, and CPU if you need get your power requirements lower, and/or just want better temps. Will update after I receive the new video card, and see if this unit can really do around 200 watts.

I bought this unit as a replacement for a less powerful model. It did the trick and the motherboard powered up right away. I have been using it ever since and I have had no complaints. It get a good review from me.

I bought this to put into a mini ITX pfsense build I was doing and it worked great. It's been running for about a year now and I have had zero issues.

I bought this to replace a nano-type PSU which was somehow sending noise (ground loop buzz plus intermittent sputtering) over HDMI and TOSlink. It took drilling for L-brackets to mount it in my Wesena mini-ITX case. Plugged it in, turned it on, hooked it up, and the noise is gone! (Well there's a very low level ground buzz with my ear within an inch or 2 of the speaker: I can live with that.) I don't know if the other PSU board was defective or simply attaching the ground wire on this one did the trick (the nanu didn't have a ground wire) but I wish I'd tried this before spending a lot of money on less effective isolators etc. Giving 4 stars only because it's new and reliability is not confirmed. Great value.

was easy to setup

This PSU should be rated at 125w max not 300 The plug and input wires get uncomfortably hot above 125w I am certain anywhere near 300 watts things will become dramatic. The Input wire size at18ga is grossly undersizsd should be at least 14ga. One star reduced because of cost for 8 pin cpu adapter and undersized input wires that i was forced to replace.
