I know a lot of us run dual PSU's. I currently don't own any fully modular supply's, but am in the market now for a couple new units. I was specifically looking at the 1300g2 and wonder if anybody has ever run it with just a jumper from the trigger to ground straight on the psu instead of using the 24pin cable and jumping it at the end of that. I only need the pcie cables and don't want to plug anything else in.

hmm explain risky. and the point is to not have that cable connected. do those pcb's actually do anything besides add a relay to connect ground and green when triggered by an external 12v signal? If that's all they do then it is really no different than just a switch on a jumper. If they do something with the 3v and 5 volt rails to help the psu load balance then I might agree with you. Is this what they do?

yes I am aware of those. all that is is a relay to connect trigger and ground when an external 12v is applied. I wont ever be turning this supply off, so no need for a switch or relay. I guess what I am asking is if most of these new power supplies, specifically the supernover 1300g2 needs something on the 5 and 3 volt rails to work long term. the 24 pin cable also connects with 2 plugs into the power supply. I am also wondering why this is and if the green wire is still doing the same thing as the older supplies?
