What to do with this cable?

[iglisca]

Hi,

I have a corsair cs550m and would like to connect 2 fans to the PSU. The PSU is semi-modular and I have a couple of cables, one of them with 3 molex female and what seems to be a 4 pin female for fans - but i'm not quite sure how to use it.

It is similar to the cable in this picture(am I allowed to post?) the second from left to right.

Do I still need to buy a molex male adaptor - something like this https://www.amazon.co.uk/15cm-Akasa-Fan-Cable-Fans-x/dp/B001J2YRU2/ref=sr_1_3?ie=UTF8&qid=1484729519&sr=8-3&keywords=molex+3pin+fan to be able to connect both fans to the PSU?

Thanks

Why not connect those fans to the mobo, unless, of course, you've used up those headers?

The cable you refer to would be a way to gain more 3 pin plugs from a molex.

I suspect that the 4 pin you are looking at is for FDDs and is a legacy connection.

Hi, I have a msi h110m with only one fan header. I bought a noctua fan 4pin which i intend to connect to the mobo and i have 2 phanteks fans 3pin (which came with the case) that i want to use as intake connected to psu.

The akasa molex to fan cable will be fine.
