Corsair PSU came w/ molex and floppy drive connectors?

Just opened up my Corsair hx750:
It came w/ 4 SATA connectors.

But I believe it came with 2 floppy drive and 4 molex connectors?

What the heck are floppy drive connectors used for? Old school dinosaur floppy drives?
And molex connectors used to be used a while ago before molex correct?
 
Some PCI devices use the floppy power connector. My sound card had one.

Some motherboards will have a molex connector to give more power to the PCIe slots when there are multi GPU configurations installed or other add in cards that need the extra power, but don't need a dedicated power source.

Molex cal also be used for case fans, but it's not advised since you can't adjust the speed on the Molex connection.
 
I actually purchased my Corsair PSU for many reasons, but the inclusion of MOLEX connections was one of them. I have a lot of old hardware, that could easily be used since the MOLEX connections are included, and the case I have has 3 fans that it came with that use MOLEX connectors. It's really more of a convenience feature than anything I would say. It's especially not a bad thing considering that the HX750 is modular, so it isn't like you've got a useless cable sticking around lol.
 
How do you power case fans? Lots of accessories such as fans, older optical drives, fan controllers, etc. use molex connectors. It's not uncommon to find a single floppy connector either, as many use it for legacy devices.
 
I used Molex for my case fans until I got a new case with a fan controller built in.
 
I'm going to laugh if you get a peripheral that has molex on it down the road.

If it's really that big of a deal to you, you can cut off the connectors that you don't use. Just make sure you don't leave any bare wire hanging and tape up any loose ends.

Edit: Oh, even better, it's modular.
Still would be worth keeping them in a box if needed though, just gives you that extra flexibility.

What do you see case fans moving to?

Eh I dunno, most of the controllers pretty exclusively have the three pin header that I've seen. All of the ones I've used recently have just been tied into the 3 or 4 prong header as opposed to the bulkier molex.

And what powers the fan controller? All the ones I've seen are 3/4 pin to the controller, and molex to the PSU.

That depends if the 'controller' is via your mainboard's firmware and powering the fans via onboard headers :p

Since I couldn't find any non-molex fan controllers via Google in a reasonable timeframe, my only rebuttal is now, "Your mother". ;)
