Should be fine as the atx power supply dying means the mobo is off so no signals are going to the gpus so they essentially get switched off. But they will still have a power supply from the server psu. Just remember that incase you dismantle the rig.

one more question actually, i couldnt find a clear answer searching
will gpu's be fine in the case that the atx power supply fails and the server psu does not?

excellent thanks a lot guys! will post a video of my farm build soon

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?

Each pcie riser can draw 75w and your mobo about 150w (based on the pico rating being 150w) so you can work out a maximum estimated usage of 525w if everything is maxed. If the risers draw their max then thats 375w.

Use a pico psu for the mobo and run it direct from a 6pin pcie connector. Thats how ive got all my rig running from a 1200w HP server psu.

Hey guys, just wondering what measures you guys use to make a server psu power your gpu's while maintaining a standard psu for your motherboard, peripherals and risers?
Ive been trying to find a definitive answer for how to connect these in the safest manner and havent had much luck
Also i cant find great pics or a writeup, but can you run a p106/gtx1060 card and riser off of the same PCI power connection with a 2x 6pin splitter?
thanks guys
