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

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.

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!

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.

The power supply on my (14 year) old mini ITX case was starting to randomly power itself off. This power supply has been running fine for a month now in my system. The system is small and only draws 30W, so I'm not stressing the power supply much. The power supply appears to be made with quality components, has clean solder joints, is very clean, and should last a long time. I'm very happy.

I've run these in different rigs for months or years now, they just work.

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.Processor Core i7-7700Graphics GeForce GT 1030

Working fine on system with average draw 50W, peak 150W. Docked a star for the 12v input connector which looks only good enough for maybe 50W. I replaced it with a 4 pin molex that is working fine.

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!!
