PSU requirements for a fan controller

[TheEak]

Right now I'm running this

foxconn A7GM-S
AMD Athlon X2 600+ @ 3.1 GHz
Radeon 4850
and 2 old IDE drives

off of an Antec Eathwatts 430.

Now my motherboard only supports 1 case fan (I was on a strict budget when I bought it) and my case is getting dangerously hot so I'm planning on getting a fan controller. I'm just not sure If my PSU could handle it.

And if it can, I'm gonna ditch my old drives and replace them with 1 SATA. would the PSU still be able to power everything?

Yes to both of your questions.
