Hello, followers of the MO-RA Church.

I thought buying a MO-RA IV 400 would be simple: connect some fans, connect the pumps, and enjoy ridiculous cooling.

Turns out, figuring out how to power and control the damn thing is the real challenge.

I'm building a MO-RA IV 400 about 1–2 m away from my PC and have already purchased most of the setup.

My current MO-RA setup (Yet to be built)

• WATERCOOL MO-RA IV 400 — Black
• MO-RA IV Tank 200 D5
• MO-RA IV Tank D5 Expansion
• MO-RA IV 200/400 Wall Mount — Black
• MO-RA IV 400 Fan Frame — 140 mm
• MO-RA IV 400 Fan Grill — Black
• 2 × HEATKILLER D5 PWM pumps
• 9 × Arctic P14 Pro fans
• Aqua Computer QUADRO
• Coolant temperature sensor
• Flow sensor — considering/looking to add
• 2 × WATERCOOL Pump 290 Cables — Connect the D5 pumps - not purchased yet
• MO-RA IV Passive Control — not purchased yet
• PCI-slot pass-through — not purchased yet

The PC is an ASUS X870E-E system with a 1250 W PSU.

What I'm trying to figure out

I'm currently considering four options:

1. Passive Control + MO-RA LINK
   The official/clean solution, but importing the Passive Control, pump cables and pass-through to India gets expensive.

2. QUADRO + direct PSU power connection
   Run a properly rated power cable from the PC PSU through a PCI-slot pass-through, take it 1–2 m to the MO-RA, and distribute the power locally to the QUADRO and two pumps.

3. Separate PSU at the MO-RA
   Power the QUADRO/pumps locally and simply turn the MO-RA PSU on before starting the PC.

4. Some other solution
   If there's a better/cleaner way that experienced MO-RA users are using, I'm all ears.

What I'm particularly interested in

If using the Passive Control, is this basically how the QUADRO interfaces with it?

PC
 ├── PSU ─────────► Passive Control
 │
 └── QUADRO
      ├── PWM ────► Fan control
      └── PWM ────► Pump control
                       │
                    MO-RA LINK
                       │
                       ▼
                    MO-RA IV
                   ├── 9 fans
                   └── 2 D5

Alternatively, can I simply use the X870E-E's T_SENSOR + PWM headers with the Passive Control and skip the QUADRO?

I already have the QUADRO, so I'm not against using it. I'm just trying to avoid spending another €100–150+ importing Watercool-specific parts if there is a clean alternative.

MO-RA veterans — what would you recommend? Particularly interested in real-world setups, photos/diagrams, and how you're handling the PC-to-MO-RA power and control connection.
