Thanks all
I have a rig that is waiting for gpus to arrive
Currently I have installed one 650w EVGA PSU supernova GS
Which is plugged into the mobo (asrock h81 pro btc)
Also plugged into the PSU right now is one VGA to 4 SATA and one VGA to 2 SATA which then plug into the PCIe riser boards
https://www.ebay.co.uk/itm/222451407125 I was then thinking that just one 650w PSU isn't going to cut the mustard on power delivery in total, nor in the number of power ports it has to power each of the gpus
So I was thinking of buying a second 650w PSU to mount into the rig along with the first, connected together which one of those "dual PSU split cable" thingys and then plug all the gpus power supplies into the second PSU
So the rig would in total have 1300W
Thoughts very much appreciated
Thankyou
