I´am interested in EVC2SE

Does this work with RTX 4090? And what else do I need besides the EVC2SE?

btw:

I´m interested in "ElmorLabs PMD-USB (Power Measurement Device with USB)", too

But it only has 3 channels for PCIe how many watts can a PCIe socket handle?

I have the Corsair 12VHPWR cable with 2x PCIe (2x 300W)

Hello,

Differences are:

Headers for I2C1/I2C2/UART changed from 2.54mm pitch pin headers to JST XH headers
Improved I2C1 performance at 400 KHz
Added fine-grain adjustments for SRC1/SRC2 DAC channels (0.01µA steps at Vfb = 0.6V)

Which RTX 4090 model would you like to attach it to? Support is based on which VRM controllers are on the card and if there are suitable soldering points.

Regarding PMD-USB you can use it with this cable: https://elmorlabs.com/product/pmd-12vhpwr-cable/

It supports 600W by using PCIE1+PCIE2 or EPS1+EPS2 channels similar to your Corsair cable.

Yes that looks suitable. MP2888 and uP9512 controllers are both supported and there seems to be easily accessible soldering points.
