What Should I Do if My Molex Fans Don't Connect to My PSU?

I recently got an Antec AX20 case that has fans requiring molex connections. However, my new PSU, a Corsair CX750, doesn't seem to have any molex ports. What can I do to make these fans work?

Honestly, if you're really struggling, you might just want to replace the fans. Molex fans can't be controlled, which means they'll just run at full speed, making them potentially noisy. There are plenty of modern fans that connect directly to the motherboard and can be controlled easily!

Look into some good options on Amazon or Newegg for SATA to molex adapters, theyโ€™re pretty cheap! But just keep in mind, if your fans are not adjustable, they might end up being loud.

The CX750 actually does come with molex connectorsโ€”you might find them labeled as PATA. So, check your cables again before you think about adapters.

You might want to consider getting a SATA to molex adapter. That could solve your issue without needing to replace your whole setup. Just make sure to get the right one that suits your needs!

WiredWizard87: Yeah, you'll need a male molex connector to a female SATA power, just double-check before buying.
