i just got one and i will see how or if it works i am using it to connect my phanteks 350x case argb lights to my asus rog b450 mb rgb header. my guess/hope is as you stated it will just make them glow with the normal rgb colors and effects but as its linked to the mb i should be able to use aura sync to control the case as well as the other 4pin rgb stuff and have them all sync up... fingers crossedI could not get that link to work. Nor could I find anything by searching for "RGB Converter" in Google, on Amazon, or on Deepcool's website. Closest I could get was video converters, not RGB lighting device converters.
AHAH! It turns out the device is called an RGB convertor - NOTE the "or" on the end! Unfortunately the website descriptions for it do not tell us what it can do, they only tell us how to plug things into it. So I can SPECULATE a bit, but I cannot say this is correct.
There are two issues that make the plain RGB and ADDR RGB systems incompatible. One is the power supply is different, and certainly I can see how a box like this could substitute a 5 VDC supply from a SATA power source from the PSU for the 12 VDC supply from a mobo plain RGB header. But the real problem comes from what type of signals are used in each system and what they can make the RGB display do. So start with the INPUT for this box, which is whatever signals are available from a plain RGB header. In that system, there is one common +12 VDC line for a lighting strip, and three separate "Ground" lines, one for each of the three basic LED colours. Along the lighting strip (or line of LED's in a fan frame) all of the Red LED's are connected to the common +12 VDC line and the Red Ground line. Likewise for the Green LED's and the Blue LED's. Simply connecting the correct Ground line for one colour to a real Ground of the power source would turn on those lights full brightness - ALL of the LED's of that colour. Connecting more than one Ground Line to the real Ground would turn on more than one LED colour, again each to full brightness giving you other colours than just the three basics. For even more colour range, the system could make the connection to true Ground not a direct connection, but through a resistance that limits the brightness of that colour. But note that in all cases the entire RGB strip length is always one colour at any one time, until the Ground line signal connections are changed by the controller running the mobo header.
In the ADDR RGB system control is quite different. It has common power supply lines (+5 VDC and true Ground), and a Control Line. Along the strip all LED's (same three basic colours) are grouped in Nodes. Each Node contains one LED of each of the 3 colours plus a Controller chip for that Node only. That chip has its own unique address, and listens to the Control Line for instruction packets coming along with its address. It manipulates only its three LED's according to its own instruction packets. Sending different colour combination codes to different Nodes along a strip can produce multiple colors all along the strip at the same time. But the plain RGB header cannot generate different colour codes at the same time - it can only generate ONE colour code (a particular combination of three Ground connections) at a time. So I can see it possible to have a converter box that takes such a one-colour code and sends it out to ALL of the Nodes on a ADDR RGB strip so that they all generate the same single colour, just as a plain RGB strip would do with that one-colour code from the original mobo 4-pin RGB header. In that sense, you certainly could build a box that substitues the correct power supply voltage for a 3-pin 5 VDC ADDR RGB strip and also converts single-colour code signals from a plain RGB header into identical single-colour code packets for ALL the Nodes in the ADDR RGB strip, and of course change to another colour when the mobo header issues that new instruction set. Then that strip would perform just like a plain RGB strip. It just would not be able to do the extra-fancy displays that a true ADDR RGB strip can do with multiple colours along the strip at the same time.
So, I can imagine how this can work. But has anyone actually got one of these and used it? What colour displays does it generate? My speculation says it WILL make the ADRR RGB strip display many and changing colours, but they will be limited to what the plain RGB (4-pin 12 VDC) system light strips can do - that is, the entire light strip is all the same colour at any one time.
