Anyone with custom cable knowledge.

Hey guys, In a bit of a pickle.

I recently done a full system upgrade and am wanting to redo all the main cables for it (24 pin, 8 pin pcie & 8 pin EPS).

I did make all cables for my previous build so I have some knowledge.

Mu psu is the Corsair AX1200i and the issue I'm having right now is with the 8 pin pci-e, specifically the split cable. I have made 3 sets of dual 8 pin cables for my gpu but they keep tripping thr psu out when using a psu tester. I have 2 different diagrams I am following for the correct locations of each cable and am ensuring that the 3 +12v cables meet the correct points on the psu side, leaving no pin on the bottom left (facing the connector). When the cable is plugged into the psu it turns on with no problem but when I connect it to the psu tester, it sparks, trips and shuts off. I can only think there's something wrong with the split I make. I use a large female molex crimp to hold them together and then solder it.

If anyone could provide me with some help or even a correct pinout diagram, I would greatly appreciate it.

Which PSU tester are you using? Because only the Thermaltake Dr Power II has an 8-pin PCIe connector to test, everything else I've seen only has a 6-pin PCIe. You're not trying to put the 8 pin PCIe into the 8 pin EPS, are you? That will do nasty things as they're wired completely differently.

The PSU should be compatible with Type 4 modular cables, and the pinout is easy, but since the PSU will use 8-pin EPS on the PSU side to serve both EPS and PCIe cables, you need to be 100% sure you're wired up correctly (same deal with my SF600 Platinum so there was lots of triple-checking).

I'd strongly suggest investing in a multimeter and testing pins manually. Those PSU testers only report if something is wired correctly, not what the load voltages are.
