Hi,
I have managed to install a Nvidia Tesla K80 into a Fujitsu Esprimo P910 E85+ but at this point I am facing the dilemma of providing 225W of continuous power (300W peak consumption) to that board (it is not a graphics board but a dual GPU accelerator).
Usually changing the ATX PSU is the way to go but this is not feasible with the Fujitsu Desktop case that has its own specific PSU which the screw holes do not fit with any standard I found on the Internet by now. Possibly, I have missed something but at the moment, I did not find any suitable replacement.
My idea is to store an ATX PSU into a dual DVD reader bay and searching for this option, I found that other people like me adopted a solution like this to support a newly installed GPU board in their cases. As we can imagine, people wish to save any effort. For this reason, I think that:
a PSU with the size of a DVD reader that can fit precisely its bay and with an ATX 24-pin adapter that gets the ground on PSU-ON pin (green cable, I think) would be very nice but probably costly considering it would be dedicated for a niche of users. A number of users can appreciate having any 8+8 pin, 6+2 pin and every other combination that a GPU board requires.
a solid plastic frame (that can be prototyped by a 3D printing machine) that allows users to use a standard ATX PSU (dual DVD bay) or FTX or Flex AT in order to fit them into those places. While ATX PSU usually have a standard size, such a standard is not as much as defined for FTX. Therefore, this plastic adapter might be a more sophisticated object than a bare simple plastic frame. Which makes it valuable, after all.
In the second case an adaptor for the ATX 24-pin connector to convey the PSU-ON grounding signal to the extra PSU is still required for a “good job done”.
Do you have any better ideas? Has anyone faced and solved this challenge before?
Best regards, R-
