Question 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!
