wiring a Long RGB adressable led strip to PSU

[roelversteeg]

I bought a 5m long rgb adressable led strip (60leds/m). It uses about 90W of power when all led's are white.

I want to connect about 2meter of strip to the inside of my case and the rest around my desk.

 

What I want to know is how do i wire this to my psu (Corsair AX860).

Can the wires handle the current (5V at total 18A devided in a strip of about 2m so 7.2A, and a strip of about 3m so 10.8A)

I want to use asus aura to control the lights via a header on the mobo and the power for the strips directly from psu

 

LED specs

WS2812 rgb strip

300 led's total 60/m

5m strip

5V dc

max A per led = 60mA

max A strip = 18A

do you have a degree in electronics? if not, i would strongly suggest you not start modding your PSU.. the power in there might kill you, even if it's unplugged.
you ruin warranty and add a significant fire risk to an  otherwise safe platform.

tl;dr - is RGB worth risking warranties and or your life?

haha you got me wrong there sorry I want to connect my wires from the strips to like a molex cable from the psu not directly inside it or something

ah, well, that's different

unless there is a fixed connector for this (which i assume there is not, hence yuour question) i would rather return the ones you got and use rgb strips that already have molex/sata power connectors included instead of macguyvering something together with the risk of shorting etc..

well I am pretty good at soldering and so on, I have done these kind of things for years. And could not find the right strips for cheap (my current one is from china 15 euros)

There definitely is a way to do this. Just hope someone replies who knows how lol

Asus Aura uses standard RGB and will not work with addressable, they are controlled completely different.  Standard RGB pinout is +12v, Ground, Ground, Ground, addressable is +5v, Data, Ground. 

Unfortunately what you want to do isn't possible.  
You would need to use standard RGB LED strips (not addressable) or use a controller that works with addressable LEDs.

so how can aura control those fancy fans that are controlled individualy (like rainbow rings and stuff) which you can see on their page

for example here it talks about addressable strips https://rog.asus.com/articles/technologies/the-evolution-of-aura-rgb-lighting-leads-to-an-official-sdk/

Interesting, haven't been keeping upto date on this as we are working on new custom parts for cases/hardware, but it seems like they have added support for addressable LEDs on some of their newer boards but fail to mention any sort of spec for compatible addressable leds. They don't mention the voltage (although almost all are 5v) but don't mention if they are 3pin addressable or 4pin addressable, I assume it will be 3pin addressable as 4pin is mainly on the older strip.

Assuming its the 3pin version, you can run the data lead to the motherboard and 5v and ground from a Molex.  Molex can handle up to 11A per pin, if they are high-quality but to be safe I wouldn't use more than 8A.  If its the 4pin version I won't comment as I used them once years ago, we mainly work with the 3pin addressable.

It is a 3 pin version yes. So if i connect my strips to two different molex cables it should be alright 7.2 A for one molex and I will make the other strip somewhat shorter so it is below 10A. The cable I use are the standard cables that come with the AX860 powersupply (they are of good quality).
