RGEEK 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!

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 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.

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

The media could not be loaded. 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).

Cables are stiff and short. I was very worried the pcb would be damaged with the amount of force required to get the 24-pin atx connector ends to go in. The frustration is compounded by the lack of alternative options of higher quality. On the bright side this one has been working well for a year of usage in a low-power mini-itx server. I do wish it had a larger voltage tolerance range so that I could run the unit off DC battery backup but an inline buck-boost converter does the work of stabilizing the power source for me. Overall if you want more versatility and quality go with a pico-box mini-itx PSU but if you're budgeting or already have a 12VDC power brick then this option works.

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.

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