Hi folks,

I am wondering if it would be possible and safe enough to power 2 X RX580 Nitro+ 8GB cards and their risers form 1 GPU slot of the PSU.

This is the GPU

and as everyone knows the RX 580 Nitro+
https://www.sapphiretech.com/en/consumer/nitro-rx-580-8g-g5

Currently, i am powering every GPU and its riser with 1 GPU slot from the PSU - 1 cable that splits and powers the 8 pin connector of the GPU and the riser with 6 pin

I was reading here and there that it should be ok if the power is not exceeding 225 W .

On Phoenix miner it shows that every GPU draws between 90 and 105W (GPUs are bios modded undervolted etc...)

So 2 RX580 Nitro+ 8GB will need 210W max.

Another question is Phoenix miner showing the consumption of the GPU and the riser in total? Or is this only the GPU? As far as i know the risers can draw up to 75W power

Thanks

You think it is not ok to power your card with 1 cable from psu? You think the psu manufacturer give you the chance to burn the psu? 1 Cable with 2x 8 pin can handle over 300w.

And all miner show wattage reading from software, this is not the real power consumption. If you want the real consumption, you must measure it at the wall.
