Hi I am looking to add more gpu's to my rig and will need to add another psu, do I need one of these Dual PSU Adapters? will it work without?
The Dual PSU adapter isn't necessary per se, it does however make it seamless and safe. The wires going between the PSU's can come out and fry components. Overall I guess it depends on how 'hands on' you want to be and how safe. We prefer these as they do make it easy and safe.
