Zotac 3090 power requirement

[bezzy3004]

Hi all just upgraded to a Zotac 3090 from 2080ti. I'm unsure of correct power cables, my 2080ti had just one cable with two 8pin plugs. Can I just use this for the 3090 or do I need to plug just one of the 8 pins in and install a second cable for the other eight pin, I'm assuming the single cable doesn't provide enough power. Many thanks Paul

Definitely use 2 separate 8 pin cables from the power supply and use at least an 850w psu

As I thought thanks for your help

yeah the zotac can pull 350w, you'll get about 60-70w from the pcie connector and the rest split on the PSU cables. You can feel them getting warm on full load

Oddly my Antec HCP 1000 is single cable but each 8 pin goes to a separate 40A rail, so works fine.
