This PSU comes with several extension to plug and unplug from the PSU.
One of this extensions have 3 molex
And the other extension have 3 molex + 1 floppy connector
I cut off the floppy conector from the extension becouse is usless, I left the extension with just the 3 molex connectors;
but when I connect any fan direct to one of the molex in this extension the fan does not work at full rpm; just like a half power.
So... when I plug the fans to the other extension, the one that does not come with floppy
the fans work at full rpm.
I tried to connect this extension (the one that does not deliver all the power to the fans)
to any other plug on the PSU and is the same, the fans just does not work out at full rpm
Is it possible that cutting off the floppy connector affected someway the whole extension ?
I mean it is just a cable, all the other extensions works Ok in any plug of the PSU but is
just this extension the one that does not deliver full power in any plug of the PSU.
I have checked the cable and it is OK, it is reallly really fine.
How else could I check this extension and why does not deliver full power on the molex.
Depending on how it was wired you may well have made that cable useless by shorting it to ground. You could probably repair it with the correct knowledge of how it was wired to maintain continuity, but I don't think that I would suggest it for you as I don't want to have someone that doesn't understand that just cutting wired connections off was a bad idea to be having their half considered home wiring repair sending voltages into a case or well really anything else near a computer.
