Commander Pro Power Limits

Good day, readers.

 

I'm gearing up for a new PC build that will include the following components of interest:

  • Hydro X Series XC7 RGB CPU Water Block (115X/AM4)
  • Hydro X Series XG7 RGB 20-SERIES GPU Water Block (2080 TI FE)
  • Hydro X Series XD5 RGB Pump/Reservoir Combo
  • ML120 PRO RGB LED 120MM PWM Fan - 3 Fan Pack with Lighting Node PRO
  • ML120 PRO RGB LED 120MM PWM Fan - 3 Fan Pack with Lighting Node PRO
  • ML120 PRO RGB LED 120MM PWM Fan - 3 Fan Pack with Lighting Node PRO
  • ML120 PRO RGB LED 120MM PWM Fan - 1 Pack

 

In short, I need to drive LED's for two water blocks, a reservoir, and 10 fans. I also need to drive the PWM signal and power for all 10 fans.

 

I would like to do this with a single Commander Pro!

 

Here is my plan for a single Commander Pro to tackle the task:

 

(Starting CoPro supported power output - 4.5A minus MCU)

 

  • CoPro Fan Ports 1 through 5


    • 2-way fan splitter with 2 ML120 Pro RGB fans on each fan port

    • 0.219A per fan * 2 fans per port = 0.438A per port * 5 ports = 2.19A total

    • Possibly less power draw if the LED's are included in the 0.219A rating for each fan, which will be handled by lighting node pro explained below.

    [*]CoPro Fan Port 6

    • Pump PWM cable

    • 0.0A power draw since pump is self-powered.

(Remaining CoPro supported power output 4.5A - 2.19A = 2.31A minus MCU)

 

  • CoPro LED Channel 1


    • Reservoir LED cable direct to CoPro channel.

    • GPU LED cable to reservoir daisy-chain connector.

    • CPU LED cable to GPU daisy-chain connector.


  • (I cannot seem to find the power draw for all LED's in the CPU block, GPU block, and reservoir. Therefore, I cannot determine a power draw to add to the 2.19A total fan draw.)
     
     
  • CoPro LED Channel 2


    • Lighting Node Pro


      • LED Fan Hub on Lighting Node Pro Channel 1

      • 5 ML120 Pro RGB fans connected to LED Fan Hub 1

      • LED Fan Hub on Lighting Node Pro Channel 2

      • 5 ML120 Pro RGB fans connected to LED Fan Hub 2

 

(Remaining CoPro supported power output - 2.31A minus MCU and unknown GPU+CPU+Res LED power requirement = ??)

 

Allllllll that just to ask, would this shake out as I plan it to? Am I overloading the CoPro unit considering it can provide up to 4.5A including MCU, 2.19A fan draw, and unknown water block + reservoir power draw?

 

I appreciate any feedback!
