Good thoughts again, though I am not quite convinced this time ;-) Thanks for all your help anyway!!!
Regarding the looks of a separate psu outside I do not mind that at all. All I care for is that it works reliable.
The whole machine lives and works under my table & I am the only person using it.
For resale its not an issue either, detach the external PSU, replace the 1080ies with the current Quadro & sell.
If someone wants the whole system with the extra cards that would be no hinderance either.
The ATX connection will make sure the external PSU starts up automatically once the internal PSU is on. Thats the point why this ATX "power good" signal connection is important (apart from that an external PSU should not be run without load.)
I heard of the separate psu units for the hard drive bays, still they are typically low power and give the heat off INSIDE the machine. Not good in my eyes.
Regarding the extremly expensive higher powered HP psu, they have no good reputation when it comes to reliability and, they do not have the right connectors & power for the higher powered cards.
If I find out how to pass on the "Power good" signal I will test the external psu solution with the exsisting Quadro. If it works I can get the 1080(ies). The external psu costs 65€ while the internal HP upgrade would cost 8x as much.
For the same cost I can almost get the second 1080....
Regarding Ti or not Ti, Vray's lead developer stated that the Ti performs 35% faster in his tests with the software.
Still regarding the price I consider dual 1080 vs 1080Ti.
Of course the Ti speed would be best used later, after a machine upgrade with faster PCI bus.
Undecided yet betweenTi or not Ti.
On to find the solution for the "power good signal".
Thanks, Pretty
