Used to put Nvidia Founders Edition 3090 GPUs (and maybe other with the same 12pin power connector) into a HP ML350p Gen 8 for rendering etc, tested in that exact configuration, with 2 GPUs in 1 ML350, connects from the black GPU aux connector under the fan tray to the 12pin on the GPU.

This WILL not mate with the White HDD connectors under there and I seriously doubt the HDD rail can provide 360W to a GPU!

The cable is approx 430mm long so you can neatly route it away for the cooling fans, it removes the need to use the Nvidia supplied 12 > 2x 9Pin adapter and fits correctly with the air baffle in place as shown.

This *MAY* work in a ML350 G9 but please check the pinning as I have not tried this.

I would also suggest extreme caution before plugging this straight into a modular ATX supply, check the wiring of the 8 pin matches!

As ever postage shown to UK mainland and collection from Guildford, Surrey is welcome.
