Well, I'm sorry to say that these cables from CableMod, at least in my case, leave a lot to be desired and have caused me more than one headache.
They look great and can't complain about their "ductiveness" compared to other nylon braided types, but when several of my molex powered devices in my rig started acting or just not starting, I started checking on all connections, only to find three pins had released themselves from the connector, thus the actual terminals where not contacting properly.
To make matters worse, I purchased a fan controller front panel, fed via a molex connector and ended up burning due to an erratic connection; never doubting about the proper power connection or cables, I returned the unit and got a replacement from the shop, free of charge. Convinced that the previous unit was faulty I spent more than three hours connecting the new fan controller (fans, temp sensors, USB, and molex power), only to find it had the same erratic behaviour... Of course, this time I checked one by one all the cables and connections and that is when I found that the molex pins (two of them) had come out of its place and were slightly further back in the CableMod molex connector; pulling back with two fingers the pin came straight out! So, for whoever has purchased this kit, please take a look at all the terminals and specially at the Molex dual cable connectors; make sure they are in the right place and solidly fixed.
I'm not prepared to buy new ones from other manufacturers, so I have purchased a few Instant Loctite Super glue and have put a drop on every connector's backside, hoping they will hold in place.... (if you wonder why I didn't return the cables, it was simply because I bought them from a local vendor who doesn't accept returns).
