pcie 6 pin to molex

pyr0_m4n · Jun 19, 2013

Is this possible? I want to attach some fans, but my psu doesn't have molex and I don't want to use the sata connectors at the moment.

Since there are molex-to-6pin adapters available (see Amazon, etc.), I don't see why not the opposite.
What's the worst that can happen?

PSU doesn't have MOLEX? I haven't seen one like that yet.

There are lots of the opposite but I've never heard of PCIe to Molex; my google search isn't turning up anything but Molex to PCIe.

Molex connectors provide a +12 volt rail (yellow), a +5 volt rail (red) and two reference grounds (black). 6 pin PCIe connectors provide 3 +12 volt rails (yellow) and 3 reference grounds (black). Since PCIe connectors don't provide a 5 volt rail it's not possible to convert them back into a full Molex connector. However, since fans only utilize the 12 volt rail, it's possible to tap some fan connectors or a partial Molex connector from it, but I'm not aware of any adapters that do so.

PCI-E to anything isn't likely, there are adapters to PCI-E because they are fairly rare connectors, you wouldn't want to waste one of them to create a couple of auxilary power cables, but you can take a SATA power cable and turn it into a pair of molex cables, there are SATA and molex multiplier cables out there two that can turn one connection into two or three if you start running short.
