Custom cables for AX1200i


Recommended Posts

Hey guys, some much needed advice required. 

I am having some issues creating an 8 pin pci-e cable that doesn't trip my system. I have created my own cables before with no problems but had to change the length for my new graphics card.

I am using a psu tester before trying them in the system properly and when plugged into the psu, it boots fine but when I plug the gpu end into the tester, it trips the system and a red light shows on the psu. This disappears when I switch off/on. I have been using a diagram for type 3 and type 4 cables (primarily type 4) as the cable compatibility shows that both types will work on my psu. I have the split cable and no pin on psu side at bottom left (when looking at front of connector, as per diagram for type 4), yet the system keeps tripping. I haven't tried type 3 yet as that shows a +12v cable is needed where the type 4 shows no pin and not sure if that means I have to have another split cable for that.

Does this mean my psu is faulty or am I not doing the split properly?

Any advice would be brilliant as I cannot find a diagram for AX1200i that includes 8 pin pci-e, only for 24 pin.

Thanks

on the GPU end, how many 12V and how many grounds do you have? that may be why it trips.

You're supposed to have 3x 12V pins and 5x GND. The split end with 2 pins is only grounds.

That's how I have it. Top and bottom left of gpu end facing back of connecter are ground with a split. Psu end, split goes into top left, facing connector. All 3 +12v on gpu end match psu end. As in diagram for type 4Screenshot_20220802-143820_Chrome.thumb.jpg.fb16dd2f93e951a87a9d9cd8bd31fc51.jpg

In these 2 pics I'm adding, the first shows split cable (black cable) heading towards psu, the second shows black cable as 2 x ground. This is how ive laud it out according to type 420220803_090243.thumb.jpg.df03d8dd5658f3e69cbb8d5446d1ff69.jpg20220803_090300.thumb.jpg.cdbd3c12304c96a59941bcfb26eb5559.jpg

I'll explain better. 1st pic shows top 4 cables Inc split (black cable) which are all GND, going towards PSU. 2nd pic shows 2 black cables and other 3 top cables as GND, heading towards GPU. Other 3 on both ends I didn't mention, are all +12v.
