I purchased some sleeved cables for my 750w SuperNOVA, but they don't seem to be responding properly to my psu. I just rebuild my waterloop in a new case...just to find out nothing turns on. After days of building and then trying to find the cause of not booting, I decided to try my default cables starting with only plugging in the 24 pin and what do you know...I get lights.

I decide to leave the default 24 pin, but use the new sleeved cables for the rest of the connections. As soon as I do that, my mobo goes dead again. Obviously, the cables is the problem. After almost 2 weeks of work, I have to tear my loop down yet again to remove the cables properly (mostly the cpu cable that is behind fans and a tube). Very frustrating.

I need to check with the community if I got the wrong cables or just bad cables. The product description said it was compatible with the G3 SuperNOVA though.

Sleeved cables I purchased: https://www.evga.com/prod...aspx?pn=100-ck-1300-b9

My psu:
Part Number: 220-G3-0750-X1
Part Desc: EVGA SuperNOVA 750 G3, 80 Plus Gold 750W, Fully Mo

So try using a 24 pin bridging plug like I am filling the loop/leak testing? I've done that and the water pump turn on still.

Also, in the 24 pin there is a missing metal wire that isn't missing on the default 24 connector.
