I have a TX2540 M1 with the 800w PSU and I would like to put in a power hungry GPU.
I noticed that the PSU has two additional 6pin connectors (but I don't have additional cables) that might provide power for the GPU (which requires two 8pin connectors).
With a little help from Google I found the "GFX | GPU cable kit" which, however, only was marketed for the M5. I ordered it anyway to have at least a look. There are quite a few cables in the box but one looks particularly promising: A3C40204168,C / A3C40204169,C / T26139-Y3946-V706 (it consists of two bunches of wires that have been tied together). On one side each of the two bunches ends in a 6pin connector

(named P1 and P3) and on the other side one bunch ends in an 8pin connector

So this could actually be what I am looking for. What concerns me, however, is that the color of the individual wires seems to switch between the connectors that seem to belong to the same bunch of wires: P1 and P3 have the yellow wires below and the black wires on top but P2 and P4 have the yellow wires on top and the black wires below. This makes me afraid that I might fry my GPU, if I put this in.
And there is yet another cable (A3C40229511,A / A3C40229512,A / T26139-Y4041-V16) which looks quite similar but with the difference that P2 branches off into a 6pin connector (P6) and P4 branches off into two 6pin connectors (P4 and P7). Here, the yellow and black wires do not seem to switch positions (the black wires are on top in all connectors) but in the 8pin connectors the "additional +2 pins" are just connected to each other via a wire loop and not with anything else. So while this looks lees prone to frying my card, it also looks a bit less capable of delivering the required power. Nevertheless, I am also hesitant to try this one because I just don't know enough about these cables and the GPU is just too expensive to risk.
Is there anyone who has successfully employed one of these cables (ideally in the same type of server) who can confirm that one of them is the right cable?
Thanks for your help!
