There really isnt a min. Fans and a pump dont consume much power at all.

The H series pump runs off your cpu fan power anyway.

Youll be fine

You're really not drawing a lot of juice with your current rig, a 12v pump and a few fans isn't going to be too taxing. 750w would probably be overkill, as TwoCables asked: what are you currently running?

Also, if this is for your sig rig that has just one 9800 GT in it, then you don't need anything more than a quality-made 350-400W power supply.  The H100 doesn't increase power consumption enough to make a difference that's worth noting.

Even with the 7950, you'd still have loads to spare with a good Seasonic smile.gif

Your 620 watts should be enough for both your 7950 and the h100, people run crossfire off of a 750ish watts powersupply so your safe.
