Question about Corsair CP-8920331 Adapter cable

I would be careful, even if the connectors are identical. If you know that Cooler Master uses the same connectors on the PSU side as corsair, then you also have to compare the pinout, they could be different, in which case you would have to extract the individual cables from the connector and rearrange them, this works very well with a Molex extraction tool or with two thin objects, e.g. Bostich clamps, but is tricky. The cable itself is very good and I can recommend it :)
