yeah, i figured it would come to that lol
Trying to cut costs if i can for the time being, as i have a lot to buy scalewise (25 rigs x 5 cards) and have access to free hp workstation psu's 400w
I was hoping to power gpu's only with the dps1200's i have (8 cards per on 10pci breakout board), it'd mean buying twice as many psu's, breakout boards and cables
figuring that the 400w psu will have just about enough headroom to run 5 risers and its cpu
Just make sure to give some room for server PSUs and don't overload them for 24hr operation. 1100-1150W consumption should be perfect and can serve you for a long time. Moreover, go with a Gold rating or plus ATX PSUs for MOB and other basic components.
So in this configuration with a regular ATX and a server psu, nothing is needed for then to work in conjunction?
like when you use add2psu adapters for dual ATX psus
No, not needed. ATX PSU should power motherboard, CPU Power, SSD (If present), GPU risers whereas Server PSU should be used to power the GPUs only. First, start the server PSU, then switch ON the ATX PSU and then power ON the system.
is there any recommended place to get the dps1200 and breakout board?
