Dear watercoolers,

I am a newbie to this space but I am planning a box for 3x5090. After lurking here for a while, I come up with this config. I am planning to power limit the 5090 to 500w each.

1 x Intel w5-3425 12C24T 3.2GHz 270W

1 x Asus Pro WS W790E-SAGE SE

8 x Kingston DDR5-5600 RDIMM 32GB KF556R36RBK8-256

3 x Nvidia 5090 32GB 600W (2-slot water cooled)

1 x Cooler Master HAF 700

1 x SilverStone Hela 2050 Platinum 2050W PSU

1 x MO-RA IV 600

1 x MO-RA IV Tank 275 D5

2 x MO-RA IV Tank D5 Expansion

3 x HEATKILLER D5 PWM Pump

9 x Noctua NF-A20 200mm fan 18.1dB 146.9m^3/h

The water cooling system is going to hook up to the CPU and the three GPU for a total of 1770W. Based on the CFM formula at wikipedia, to dissipate heat to have an effect of -40C will need 1321.5m^3/h. This is about the same as nine Noctua fans’ 1322.1m^3/h. That’s why I picked the MO-RA IV 600 radiator.

Do you think this system is feasible? Am I missing any major components? Thanks a lot in advance.
