ARGB to PSU?

[NorKris]

If ur planing to run more amps than MB / controller provides.  Can you run  5v and ground from PSU directly and the signal wire from MB / controller?

 

any1 try'd this? 

[manikyath]

with aRGB stuff, i assume that the header itself just has the 5v and gnd pins go straight to the nearest power rails.. i'd have to measure a motherboard to test this, and i'm not about to disassemble my pc to probe stuff.. but i assume there's no reason why you couldnt...

 

also, isnt aRGB limited by number of LEDs, rather than current draw?

[NorKris]

the limit in LEDs is on current-level

no it just repeats its self.

mb header is max 3 amps

you can pull power form the psu and the data and ground from the mb

 

rgb on the other hand is a bit different as you need to get a repeater then get power form the psu to the repeater just like injecting power in long strips in rooms.

power and ground from the psu right?

 

Yesterday i actually found a pic of this config that you posted, and i wanted to ask you about that. put then  Crazy Joe pres 45 was speaking  and i fell asleep

I tested it now with almost 5A in ARGB's. That Sata connector gets HOT 

5v and ground from SataPower and the signal wire from the CM ARGB controller

you have 5 amp of strips? or argb devices? maybe split them up in to two sets with 2 sata power.

 

i think some one said sata connector should do like 20ish amps and i dont no about the wire gauge coming off of it. should do 5amps thow i would think.

oh looks like its only 4.5 amps of sata and more for molex my bad. good to no.

im at 4,56 in my test setup!

 

judging from the heat, the "bottleneck" is at the SataConnector not at the thin ARGB wires.. they cool and good

i would do 2 sets to be safe. or 1 molex

Just a test, in my plans for the next PC upgrade when(IF) a 3080 lands, im only doing 3,7a.  but even that is more than what CM H500m controller / MB can handle

another interesting find: it only gets hot when the LED's are white

ya solid white or red i think is the most demanding. i guess white because it uses all 3 colors. ya ill have to update my guide on the different of sata and molex.
