Asus Aura RGB LED control - Beyond 2 meters?

Hello all,

I intend on getting one of the Asus motherboards that have the Aura RGB LED headers that let you add up to 2 meters (vague..) of regular 5050 RGB LED strips to sync up with your motherboard and potentially strix GPU lighting. Cool stuff, right?

However... I wanted to light up my entire desk with LEDs, and I was wondering if theres a way to tap into the computers RGB control, to attach more than 2 meters somehow. Could it be as simple as hooking one of these up to the header? http://ledlightingsave.com/index.php/waterproof-rgb-led-amplifier-extender-for-led-strip.html

All the info you need is here
AURA RGB Strip Headers support standard 5050RGB LED strips with a maximum power rating of 12V/2A, it's best to keep the length within two meters for best brightness. If you're shopping for them online, just search for 5050 RGB LED or 5050 LED strip and there will be more than enough options to choose from.

When you speak of lighting the entire desk, you might want to do some back calculations/illustrations as to the implementation since the wires will be coming out of your case, it will be a bad idea should you move your chassis for some cleaning or in the event you want to just move the system for any decorative reasons.

It would be a good idea to have the LED's for your desk on a separate stand alone controller that isn't connected to the system in any manner.

I have an ASUS MAXIMUMS VIII Hero alpha with the built in RGB header. I was also confused with the "2 meter" rule. I looked into this a lot and realized that as long as the voltage matched, it would work without under-powering the lights. I bought this: https://www.amazon.com/gp/product/B00W3G3HJU/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 and it works greatttt! Look at my Profile Picture, those are the same strips connected to my mobo.

That looks slick, exactly where I wanted to take this thing. ;) You're not running into issues with overcharging the FETs responsible for powering the lights? Howmany feet of it did you end up plugging into the mobo (directly)?

I apologize for the late response, I was on vacation.
I used all of the cable. I accidentally crushed some of the lights so I cut the last 2.5 feet off where I crushed a few lights and just used the strip I cut as a back-light for my monitor. As for overcharging the FET's..I'm not sure what you mean by that, but if you're asking if the headers are overheating or there are any voltage issues with any of the lights or components...there are not. I can run some tests for you, just tell me which tests to run.

So about 14 feet (4.26m) of regular 5050 LED strip is running without any beef at all? Thats good news. :) I'm not sure where the LED drivers are on the motherboard, but "overdriving" them by more than double of the factory specs seems dangerous. Though if 14 feet works just fine for you, why would asus suggest a 2 meter limit.. They should just specify milli-amps IMHO.

FETs or voltage regulators usually look like this (regular):

So nothing is particularly hot near the aura header then?
The plug itself wont get hot.

I think I specified just now that the plug itself isn't the thing that gets hot, though. :p
You don't happen to have a FLIR camera, do you? :3

I meant that nothing around the header is hot either, my bad! I don't have a thermal camera(not sure that I would even ever need one!) I just used my iPhone 6+ camera and made the colors look pretty haha

Since its still a dark picture, there is a lot of noise and not a lot of detail. I don't have a wide angle lens for my dslr to get a good picture of my setup in the dark.
