Hello. I'm looking to add a second power supply to my rig. I currently have 1 psu powering everything (mobo, ssd, cpu, 3 gpus, 3 risers). I just got a 4th gpu and looking to connect it to second psu (first psu doesn't have enough connectors). I will also need Add2psu to turn on/off both psu at the same time

So do you think it's ok to just connect a gpu and a riser only on second power supply?
