EZDIY-FAB 12V to 5V RGB Converter, 3-Way Splitter, SATA Connector, 50 Color Modes, 100x 5V LEDs

Helped me with the problem of older motherboard 12v argb headers. Didn't have to purchase any additional equipment, all necessary wires included. Easy installation.

It's very simple to set it up with no fuss at all. It's been running great so far. I have my liquid cooler running full speed.

My motherboard only has one 12v RGB header (4-pin). I purchased the wrong fans - 5v (3-pin). This controller/adapter saved the day. I was able to connect all 3 fans and connected the 4-pin output to motherboard. Although I later noticed that there isn't any benefit of connecting them to the motherboard because the controller has a nice option of using your case's Reset button to control the lights. You won't have the power reset option anymore (when do you really use it?) but you can control the RGB lights by pressing the reset button. On the other hand, when you connect the controller to the RGB header on the motherboard, after every shut down, the colors revert to the color you have set in BIOS. So it's actually preferable to omit the motherboard connection as far as the lights go. Overall, I'm very happy with it.

UPDATE: Several months later...the unit fried itself about a week ago.No idea what, probably just cheap circuitry. Apparently, 12v to 5v step down was more than this thing could handle long-term.I decided to go with a different device from another manufacturer, which uses the USB ports on the MB for the control functions, and draws the 5v power from a SATA connector. (I had considered this originally, but it was more expensive, and required (for my PC) a USB splitter (adding to the cost). We'll see how this goes.Old review:Okay, so I have built several machines in the last 18 months now, sort of a renovation of sorts as the purpose built PCs I have were getting long in the tooth--read that as old as dirt--in some cases.Anyway, Built a Gaming PC last summer (2020) and for the first time I was going to put some RGB stuff into it (two LED strips and RGB fans). Okay, that was the second time...sort of. 20 years ago, when LED stuff was first coming into consumer use, I put some LED fans and I think it was called "electro-wire" or something like that...basically it was molex connector wires that had tiny LEDs in them. NOTHING like today's RGB stuff--no sync software or control, ONE color only, it just lit up when power was applied.Anyway, the board I bought last July was a current board, and it had the 5v RGB headers ASUS started putting onto the more recent boards...Fast forward to May of this year (2021). My now 8 year old production PC, the one that Office and my emails and all that stuff was installed on was showing it's age. (i7 3rd generation chip.) So I decided to start gathering parts and planning a new PC that would replace that old Dell XPS.I ended up doing a Ryzen 5 chip, with plenty of memory, yada yada yada, and changed it all around at least once. In the end I built it into a Phanteks Enthoo Pro 2, with space for 15 fans AND up to 4 radiators, two of which **could** be 480mm rads. The other two would have to be 360mm. And even then, you would have to be VERY careful what order you put it together in, because certain parts wouldn't fit if you did "B" before "A".This PC would be future-proofed, in that I can still double the memory, without taking any out. LOTS of space for more drives, if I want them. Space for vertical GPU mount (which I did). And water cooled, with two 360mm rads.And those fans? I have 14 RGB fans six of which are in the 2 rads, and eight are intake fans. Fans run slower, and therefore quiet. That, plus the idea that it's water cooled, meant that when I closed up the case, I can't even hear the pump. And I have excellent hearing.My one fatal (well not really) mistake was the ASUS system board only had the 12v RGB header--I saw an RGB header, and didn't pay attention to the voltage.I searched long and hard for SOMETHING to fix the problem (12v vs 5v RGB). I really liked the fans from my gaming PC, and they're inexpensive for what you get, and so I had wanted to buy more for this PC. But the RGB for them is 5v.I found that I could have done the RGB through a USB-c connection in a box that would sit inside the case. But it was $50. That was a no-go. (See update above)This little box does the job ALMOST perfectly.My only caveat is that it takes about a minute after the Windows Desktop appear and the PC is ready to rock and roll, before the RGB syncs and recalls the last setting, and does it's thing.Before that, Rainbow Puke mode everywhere.Not 100% sure if it's the box waiting for a signal to sync everything, or just the motherboard treating the RGB as a low-priority, but if you can stand the rainbow crap for a bit, it's great after that. I don't go in for the shifting, rippling and swirling colors some like with RGB. One or two static colors is fine by me. And this does that A+.

The media could not be loaded. Works pretty good not perfect on the sync but dose sync to alot of the motherboard setting. Over all I'm very happy with the results and it beats buying all new fans.

So it took a little bit to get this thing working, but once I did I'm very happy with it actually.I have an MSI x470 Gaming Plus, which only has 12v 4pin RGB headers on it. I connected the power to a SATA cable, connected the other to my motherboard RGB header and then connected my aRGB devices (Phanteks Halos Luxe Digital) to the 3pin splitter. Voila, it works!However, here's where I think a lot of people may find this review useful. I wanted to use one of the preset lighting effects of the RGB converter and it kept just defaulting to my motherboard's lighting. I opened my glass panel, pressed the button and it switched to the desired effect. Then when I rebooted, it would be back to motherboard settings. I was NOT going to do this every time I booted up, so I opened MysticLight and tried playing around with the settings. MysticLight for my motherboard only had basic lighting settings so I couldn't do any lighting effects except solid color with a breathing, flashing, etc effect on it. The RGB hub does not do "breathing" effects well. When it breathes, it just kinda flickers and shuts off, then comes back on again.So I had a thought... if this adapter has preset lighting effects and I only want to use those, why do I need to connect it to my RGB header at all? I disconnected the 4pin rgb cable from the header (but obviously kept the SATA power connected) and the hub finally would remember the effect that I wanted.The reason I gave this 3 stars is because there's really no way to attach the hub to your computer. Many of the other hubs have a magnetic back or something, but this I had to zip tie to the bottom of my case (I have the product circled in my image). I also found that the 3 pin connectors on the splitter were really flimsy and bend/detach easily. After I connected the RGBs to the hub, I actually put electrical tape around the connector because the male and female connectors ripped apart from one another and bent one of the pins when I was trying to do some cable management. Other than that, it works as intended!TLDR:- When connected to motherboard, it defaults to motherboard lighting settings- Using MysticLight, there aren't any cool effects, and the "breathing" effect does not work properly- IF YOU WANT TO USE THE HUB'S BUILT IN PRESETS... DO NOT connect the 12v 4pin to your motherboard RGB header- I recommend electrical taping the connections together from the 3pin splitter to your RGB devices, as it is flimsy and doesn't stay together well.Hope this helps someone else looking for RGB/aRGB solutions for their PC!
