HP workstations are spected to run with several drives/memory/pci-e cards installed
i'm not sure if your model has a higher wattage supply that is used when running high power cpu's and a fully decked out system (all drive bays/memory/pci-e slots filled) however if the card(s) have power connectors, then you need to determine what each card draws and see if it exceeds the existing supply
what i can say is that your hp service manual will list the supply(s) wattage and how much can be drawn from the supply
with the above said, i will point out that the pci-e slot delivers 75 watts per slot and the stock power supply is designed to work without issues with all spci-e / ram slots filled so for your use a video card with no aux power connector is well within the allowed power spects, no other changes need to be done
next, HP uses a sustom power supply/connector. the pinouts can again be found in the HP service manual
the person who told you to connect a generic 24/20 pin adapter will possibly cause you to damage the pwr supply or motherboard or both since the system does not use a axt style supply it is a micro ATX supply as i recall

Has anyone had success at installing a psu into the z240? I ordered an adaptor from www.moddiy.com, and it did not operate. I’m currently working with them to either get a replacement adaport to a refund. Will update the post to let everyone how the company is at returns.

I have not gotten the PSU to work. The adaptor from Moddiy.com didn't work. After emailing with them several times, the company sent another adaptor to try, but it didn't work. I also ordered an adaptor from ayagroup.com, very similar adaptor, and it did not work. I tried a new PSU but got the same results. I changed the pins around the 6 pin connector, followed all the schematics I found on the web, but still no luck. I am waiting to hear back from the Tech Support with ayagroup. If I figure it out I will post. Anyone have any luck getting an ATX PSU to work in a Z240?
